Colombia shows a high density and variety of bird species, making it one of the most diverse avian territories globally. Antioquia ranks among the top four provinces with the greatest variety of bird species, underscoring the importance of research efforts on the local bird fauna. Therefore, this study aimed to identify bacterial agents in the blood of wild birds from the municipality of Jardín (Antioquia, Colombia) by 16S qPCR sequencing. A descriptive cross-sectional study was conducted using non-probabilistic convenience sampling. Wild birds were captured using mist nets and blood samples were collected from each animal via puncture using sterile lancets in the brachial vein, and a drop of blood was collected on filter paper for qPCR analysis. The 16S gene in bacterial genomes was found in 13 out of 46 wild birds of the Passeriform and quasi-Passeriform orders, captured at three different locations within the study municipality at altitudes ranging from 1,665 to 2,034 m.a.s.l. Seven different bird species were recorded and four different haemobacteria were identified (i.e. Exiguobacterium spp., Escherichia coli, Stenotrophomonas spp., and Stenotrophomonas maltophilia). This study contributes to the knowledge in Colombia by identifying four different hemobacteria in wild birds. Further research is required on the health status of these birds and the attributable impacts on their populations and other related factors, including humans. [ABSTRACT FROM AUTHOR]

Veal calf welfare is of critical concern, as various management practices can contribute significantly to negative effects on health and welfare outcomes. The present review aimed to systematically collect and analyze the available evidence regarding the management strategies affecting the well-being of male calves worldwide, according to the five domains model. A systematic search was conducted for studies published until March 31, 2023, in five electronic databases (i.e., OVID®/MEDLINE, PubMed®, SciELO, Redalyc, Web of Science™). Only articles published in peer-reviewed journals were considered, and inclusion and exclusion criteria were established a priori and maintained throughout the systematic process. Thirty-six articles underwent the final inclusion criteria. All were published in English, in 15 journals, and between 1997 and 2023. The relevant articles reported management practices according to each of the five domains. Management strategies with a negative effect on calf welfare included inadequate feeding of high-optimal colostrum within a few hours of birth, lack of a colostrum management program, dehorning/castration without local anesthesia or analgesia, and long transportation of <14-day-old calves. Opportunities to improve male calf welfare included management practices such as ad libitum feeding, early provision of solid feed, socially grouped housing, adequate hutch space, and pain management during routine productive procedures. None of the studies were directly related to domain 5 (mental status). In general, there has been an increase in the number of studies on male calf welfare over time. Several management strategies can be considered or improved around new policies and management programs in male calf populations in consideration of the five domain approach. [ABSTRACT FROM AUTHOR]

Background: Rabies virus (RABV) is the etiologic agent of rabies, a fatal brain disease in mammals. Rabies circulation has historically involved the dog has the main source of human rabies worldwide. Nevertheless, in Colombia, cats (Felis catus) have become a relevant species in the epidemiology of rabies. Aims: To characterize rabies cases in humans in Colombia in the last three decades in the context of the epidemiology of the aggressor animal. Materials and Methods: We conducted a retrospective longitudinal epidemiological study of human rabies caused by cats' aggression, collecting primary and secondary information. Variables considered included the demography of the patient, symptoms, information about the aggressor animal as the source of infection and the viral variant identified. Results: We found that the distribution of rabies incidence over the years has been constant in Colombia. Nevertheless, between 2003 and 2012 a peak of cases occurred in rural Colombia where cats were the most frequent aggressor animal reported. Most cats involved in aggression were unvaccinated against rabies. Cat's clinical signs at the time of the report of the human cases included hypersalivation and changes in behaviour. Human patients were mostly children and female and the exposure primarily corresponded to bite and puncture lacerations in hands. The RABV lineage detected in most cases corresponded to variant 3, linked to the common vampire bat (Desmodus rotundus). The geographical presentation of cat borne RABV in humans occurred along the Andes mountains, epidemiologically known as the rabies red Andean corridor. Discussion: By finding cats as the primary source of rabies spillover transmission in Colombia, this report highlights the importance of revising national rabies control and prevention protocol in countries in the Andes region. Conclusion: Our results demonstrate that rabies vaccination for outdoor cats needs to prioritize to reduce the number of rabies‐related human deaths. [ABSTRACT FROM AUTHOR]

Control strategy, Dairy cattle, Eradication, Johne’s disease - Abstract
Background: Mycobacterium avium subsp. paratuberculosis is the causative agent of paratuberculosis (PTB), incurable enterocolitis, affecting domestic and wild ruminants. Economic losses, impacts on animal health and welfare, and public health concerns justify its herd-level control.Aim: To systematically collect information to answer: What are the control and eradication strategies of PTB in dairy cattle worldwide?Methods: The search procedure was carried out on October 2nd, 2019, and updated on August 3rd, 2021, using OVID®, SciELO, and Redalyc databases, and the registers from the International Colloquium on Paratuberculosis (1991–2018). The inclusion criteria considered articles published in English, Portuguese, and Spanish and in peerreviewed journals. The exclusion criteria included irrelevant topics, species other-than bovines, and not original articles. Definitive studies were obtained through the consensus of the authors on eligibility and quality. Data extraction was performed, considering bibliographic information, control and outcome strategies, follow-up time, and results.Results: Twenty-six relevant studies were found, reporting the use of three grouped control strategies: hygiene and management strategy (HMS), test-and-cull strategy (TCS), and vaccination strategy (VS). The HMS was the most common one (20/26), followed by TCS (17/26) and VS (7/26). Combined control strategies such as TCS-HMS (12/26), TCS-VS (1/26), and HMS-VS (1/26) were also described, and the consideration of the three control strategies (TCSHMS-VS) was reported in two articles. The HMS included practices such as neonates/juvenile livestock hygiene, biosecurity, prevention of infection introduction into the herd, and environmental management. Within HMS, the most frequent practices were to remove calves from their dams as soon as possible after birth and to keep the minimal exposure of calves and heifers to adult cattle. As limitations, within the HMS, it is considered that some strategies cannot be included due to lack of compliance, or the application of the same strategy among one study and another may have a different degree of interpretation; publication bias was not controlled since the results of the control programs in endemic countries may be not available.Conclusion: The main PTB control strategies in dairy cattle worldwide are HMS, TCS, and VS. The use of one or several combined strategies has been found to succeed in controlling the disease at the herd-level.

Mouth-related neoplastic and non-neoplastic lesions are commonly found in dogs and cats, and their diagnosis and classification are important for treatment planning and prognosis. This retrospective study analyzed mouth-related lesions in dogs and cats between 2000-2019 from the animal pathology laboratory of the Universidad de Antioquia, Medellín, Colombia. A total of 640 mouth-related lesions affecting 572 dogs (89.4%) and 68 cats (10.6%) were reviewed. Lesions were classified as neoplastic or non-neoplastic. The average age for neoplastic lesions was 8.6 years in dogs and 6.4 years in cats, while for non-neoplastic lesions the average age was 7.7 years for dogs and 5 years for cats. Data was analyzed using descriptive statistical methods according to year and source of report, demographic information for the animal, location of the lesion, and diagnosis. Tissue origin and behavior were variables considered for neoplastic lesions. Melanoma was the most common neoplasia in dogs and squamous cell carcinoma was most common in cats. The most frequent non-neoplastic lesion in dogs was gingival hyperplasia, while in cats the inflammatory lesions showed a wide range of morphological diagnoses. This study described many pathological lesions affecting the oral cavity for both dogs and cats and provides useful epidemiological data for both pathologists and clinicians. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The results from automated equipment and peripheral blood smears allow correlating clinical data with cellular blood counts (CBC), generating information on pathologies of hematological and non-hematological origin in dogs. Objective: To describe qualitative and quantitative magnitudes of CBC in healthy donor dogs of a blood- bank in Medellín (Colombia). Methods: A descriptive-prospective study was carried out from 146 records of CBC results from a blood-bank. The samples were processed by automated equipment, and trained personnel performed the observation of peripheral blood smears to collect qualitative information. Variables such as age, sex, breed, quantitative results, and observations of the peripheral blood smears were considered. For the definition of biological intervals (BIs), the mean and two standard deviations were used for the data with a normal distribution. Otherwise, the 2.5th and 97.5th percentiles were used. Results: The size, granularity, and cytoplasmic vacuoles in monocytes and polymorphonuclear eosinophils, as well as the presence of Barr chromatin and occasional circulating erythroblasts, were remarkable findings to the peripheral blood smear. With the standardization of data obtained from dogs of large and giant breeds, the present work provides BIs for some of the CBC data in the studied population. Conclusion: The findings of the present study allow approximations to the definition of alterations in blood cells and their counts, which can guide the veterinarian towards an early diagnosis in dogs., Antecedentes: As informações obtidas de equipamentos automatizados e esfregaços de sangue periférico permitem correlacionar os resultados clínicos e de hemogramas, gerando informações interessantes sobre patologias de origem hematológica e não hematológica em cães. Objetivo: Descrever as magnitudes qualitativa e quantitativa do hemograma em cães saudáveis, doadores de um banco de sangue em Medellín (Colômbia). Métodos: Foi realizado um estudo descritivo-prospectivo a partir de 146 registros de resultados de hemograma encaminhados por um banco de sangue. As amostras foram processadas por uma equipe automatizada e pessoal treinado observou o esfregaço de sangue periférico para a coleta de informações qualitativas. Foram consideradas variáveis como idade, sexo, raça, resultados quantitativos das amostras e observações do esfregaço de sangue periférico. Para a definição de intervalos biológicos (IBs), foram utilizados a média e dois desvios-padrão para os dados com distribuição normal. Caso contrário, foram utilizados os percentis 2,5 e 97,5. Resultados: O tamanho, a granularidade e os vacúolos citoplasmáticos dos monócitos e das células polimorfonucleares dos eosinófilos, bem como a presença da cromatina de Barr e ocasionais eritroblastos circulantes foram achados marcantes na disseminação do sangue periférico. Com a normalização dos dados para cães de raças grandes e gigantes, o presente trabalho fornece IBs para alguns dos dados de hemograma na população estudada. Conclusão: Os achados do presente estudo permitem aproximações à definição de alterações nas células sanguíneas e suas contagens, o que pode orientar o médico veterinário responsável pelo diagnóstico precoce em cães., Antecedentes: Los datos obtenidos de equipos automatizados y extendidos de sangre periférica permiten correlacionar la clínica y los resultados del hemograma, generando información de interés sobre patologías de origen hematológico y no hematológico en perros. Objetivo: Describir las magnitudes cualitativas y cuantitativas del hemograma en perros sanos, donantes de un banco de sangre en Medellín (Colombia). Métodos: Se realizó un estudio descriptivo-prospectivo a partir de 146 registros de resultados de hemograma remitidos por un banco de sangre. Las muestras fueron procesadas por un equipo automatizado y personal entrenado realizó la observación del extendido de sangre periférica para la colección de información de corte cualitativo. Variables como edad, sexo, raza, resultados cuantitativos de las muestras y observaciones al extendido de sangre periférica fueron consideradas. Para la definición de intervalos biológicos (IBs) se utilizaron la media y dos desviaciones estándar para los datos con distribución normal. De lo contrario, se utilizaron los percentiles 2,5 y 97,5. Resultados: El tamaño, granularidad y vacuolas citoplasmáticas en monocitos y polimorfonucleares eosinófilos, así como la presencia de Cromatina de Barr y eritroblastos circulantes ocasionales fueron hallazgos llamativos al extendido de sangre periférica. Con la normalización de los datos para caninos de razas grandes y gigantes, el presente trabajo aporta IBs para algunos de los datos del hemograma en la población estudiada. Conclusión: Los hallazgos del presente estudio permiten aproximaciones a la definición de alteraciones en las células hemáticas y sus conteos, que pueden orientar al médico veterinario hacia un diagnóstico temprano en perros.

Eye-related neoplasms in dogs have a significant impact on visual ability, comfort, and longevity. Therapeutic alternatives and prognosis vary according to type of neoplasm and its anatomical location. Objective: To describe the frequency and distribution of eye-related neoplasms affecting dogs in the Aburrá valley (Antioquia province, Colombia). Methods: A retrospective collection of eye-related neoplasms in dogs, diagnosed at the Animal Pathology Laboratory of Universidad de Antioquia (Colombia), was conducted. Data spanning from years 2005 to 2017 were used. Records included age, sex, breed, neoplasm type and location, and cellular origin of neoplasm. A total of 250 eye-related-neoplasm reports affecting 246 dogs were analyzed -one report per animal, with the exception of four animals with both eyes simultaneously affected by the same type of neoplasm. Results: Animals between 8 and 11 years of age were more frequently affected by eye-related neoplasms (43.9%). Labrador retriever (19.1%), mixed breed dogs (13.4%), and Poodle (12.2%) were the most frequently affected breeds. Neoplasms affected the eyelid in 76.8% of cases. Meibomian gland adenoma was the most frequent neoplasm (22.8%), followed by Meibomian gland epithelioma (20.0%), squamous cell carcinoma (8.8%), and melanocytoma (7.2%). The cellular origin of neoplasms was epithelial in 73.6% of the cases. Conclusion: Meibomian gland adenoma was the most common eye-related neoplasm. To our knowledge, this is the first retrospective report aimed to eye-related neoplasms in dogs published in Colombia. RESUMEN: Antecedentes.

- Abstract
The regional mastectomy in canines is considered as an intense-pain degree surgical procedure in bitches, which requires an effective post-sur-gical analgesic therapy for the well-being of patients. The conventional systemic analgesic pharmacological management in oncological patients is deficient and is mainly based on non-steroidal anti-inflammatory drugs (NSAIDs) and/or low potency opioids. The present report aimed to describe post-mastectomy analgesic management in two bitches, using lidocaine as a drug-therapeutic option administered through a perilesional anal- gesic diffusion catheter (MILA®). Both patients were subjected to regional mastectomy. After removing the breast mass for each case, a perilesional catheter was placed and the lidocaine was administered at 2 mg/kg/hour intralesionally, by constant diffusion through a catheter and a perfusion syringe. Measurements of physiological and pain variables were collected using the University of Melbourne Scale (UMPS) in both patients every 2 hours (T0-T12) for 24 hours. Both patients showed a decrease in UMPS score during the post-surgical observation period and there were no sig- nificant changes in the measurements of the physiological variables. The intralesional infusion of lidocaine applied in the two patients subjected to mastectomy on this report achieved an effective post-surgical analgesia state., Resumo A mastectomía regional em caninos é considerada um procedimento cirúrgico comgrau de dor intenso, que requer uma terapia analgésica pós-cirúrgica efetiva que atue em o bem-estar dos pacientes. A terapia farmacológica sistémica analgésico convencional nestes pacientes de características oncológicas é mau e baseada principalmente na antinflamatorios não esteroide (AINE) e/ou de opioides baixa potência. O objetivo deste trabalho é descrever a terapia analgésica pós-mastectomía dois cães fêmeas, através da utilização de lidocaína como opção terapêutico medicamentoso administrado o fármaco através de um cateter de difusão perilesional analgésico (MILA®). Duas cadelas foram submetidas a mastectomía regional. Após a remoção da massa mamária para cada caso, um cateter perilesional foi colocado e lidocaína foi administrada a 2 mg/kg/hora por via intralesional, por difusão constante através de cateter e seringa de perfusão. Medidas de variáveis fisiológicas e de dor foram feitas usando a escala da Universidade de Melbourne (UMPS) em ambos os pacientes a cada 2 horas (T0-T12) por 24 horas. Ambos pacientes mostraram uma diminuição no escore de dor de UMPS durante o período de observação pós-cirúrgica e não houve mudanças significativas nas medidas das variáveis fisiológicas. A infusão intralesional de lidocaína aplicada nas duas cadelas submetidos à mastectomía deste relato alcançou um estado analgésico pós-operatório eficaz., Resumen La mastectomía regional en caninos se considera un procedimiento quirúrgico con un grado de dolor intenso, por lo que exige una terapéutica analgésica posquirúrgica efectiva que actúe a favor del bienestar de los pacientes. El manejo farmacológico analgésico sistémico convencional en pacientes de carácter oncológico es deficiente y está fundamentado principalmente en antinflamatorios no esteroidales (AINEs) u opioides de baja potencia. El objetivo del presente reporte es describir el manejo analgésico posmastectomía en dos hembras caninas, mediante el uso de lidocaína como opción fármaco-terapéutica administrada a través de un catéter de difusión analgésica perilesional (MILA ®). Ambos pacientes fueron sometidos a mastectomía regional. Luego de retirar la masa mamaria para cada caso, se instauró un catéter perilesional y se administró lidocaína a 2 mg/kg/ hora de forma intralesional, mediante difusión constante por medio de un catéter y una jeringa perfusora. Se realizaron mediciones de variables fisiológicas y de dolor mediante la escala de la Universidad de Melbourne (UMPS) en ambos pacientes cada 2 horas (T0-T12) durante 24 horas. Ambos pacientes mostraron un descenso en el score de la UMPS durante el periodo de observación posquirúrgica y no hubo cambios significativos en las mediciones de las variables fisiológicas. La infusión intralesional de lidocaína aplicada en los dos pacientes sometidos a mastectomía del presente reporte logró un estado de analgesia posquirúrgico efectivo.

- Abstract
Conventional therapies for oxygen supply used in the veterinary clinic may be inefficient when offering a satisfactory recovery to post-surgical patients under chest surgical procedures with hypoxemic respiratory failure, de- manding strategies to improve oxygenation indicators. The present work describes the use of high-flow nasal cannulas in two patients submitted to chest surgeries and under general anesthesia. Patient #1 was submitted to a subphrenic pericardiectomy by thoracoscopy, and patient #2 was submitted to a percutaneous rib fracture reduction by a chest tube. Both patients were recovered with a high-flow oxygen therapy in the post-surgical phase at flow rates of 600 and 1,071 mL/kg/minute, respectively. The oxygen was delivered using a commercial device of active humidification, non-condensable suction with heating system and bilateral nasal cannula, offering an air temperature of 37 ºC, humidity of 98% and inspired fraction of oxygen of 50%. A percutaneous gasometry was performed (dorsal metatarsal artery) after 15 minutes of extubating of the patient, and a second arterial sample was collected 60 minutes after the installation of the high-flow device. An increase in the partial pressure of oxygen (PaO2) was observed without an increase in the partial pressure of carbon dioxide (PaCO2). Additionally, both patients reported satisfactory tolerance to the device. High-flow nasal cannulas should be considered within non-invasive ventilatory support strategies during post-extubating in patients submitted to chest surgeries., Resumo As terapias convencionais para oxigênio usado na clínica veterinária podem ser ineficientes quando oferecendo uma recuperação satisfatória dos pacientes pós qirúrgicos sob procedimentos peito insuficiência respiratória hipoxêmica exigindo estratégias para melhorar os indicadores de oxigenação. O presente trabalho des- creve o uso de cânulas nasais de alto fluxo em dois pacientes submetidos a cirur- gias torácicas sob anestesia geral. Paciente #1 foi submetida a pericardiectomia subfrênica por toracoscopia e paciente #2 foi submetida a uma redução percutânea da fratura de costela com tubo torácico. Ambos os pacientes foram recuperados no pós-operatório com oxigeno terapia de alta vazão nas vazões de 600 e 1.071 mL/kg/ minuto, respectivamente. O oxigênio foi entregue através de um dispositivo comercial de umidificação ativa, tubuladura não condensável com sistema de aquecimento e cânula nasal bilateral, oferecendo temperatura do ar de 37 ºC, umidade de 98% e fração inspirada de oxigênio de 50%. A análise gasométrica percutânea (artéria metatarsal dorsal) foi realizada 15 minutos após a extubação do paciente e uma segunda amostra arterial foi coletada 60 minutos após a instalação do dispositivo de alto fluxo. Um aumento na pressão parcial de oxigênio (PaO2) foi observado sem alterações na pressão parcial de dióxido de carbono (PaCO2). Além disso, tolerancia satisfatória ao dispositivo foi relatada por ambos os pacientes. Cânulas de alto fluxo devem ser consideradas dentro das estratégias de suporte ventilatório não invasivo durante a pós-extubação em pacientes submetidos a cirurgias torácicas., Resumen Las terapias convencionales para el aporte de oxígeno usadas en la clínica veterinaria pueden ser ineficientes al momento de ofrecer una recupe- ración satisfactoria de los pacientes posquirúrgicos bajo procedimientos a tórax con falla respiratoria hipoxémica, requiriendo estrategias que mejoren los indicadores de oxigenación. El presente trabajo describe el uso de cánulas nasales de alto flujo en dos pacientes sometidos a cirugías de tórax bajo anestesia general. El paciente #1 fue sometido a pericardiectomía subfrénica por toracoscopía y el paciente #2 fue sometido a una reducción percutánea de fractura de costillas con tubo a tórax. Ambos pacientes fueron recuperados en el posquirúrgico con oxigenoterapia de alto flujo a caudales de 600 y 1.071 mL/kg/minuto, respectivamente. El oxígeno fue en- tregado a través de un dispositivo comercial de humidificación activa, tubuladura no condensable con sistema de calefacción y cánula nasal bilateral, ofreciendo una temperatura del aire de 37 ºC, humedad del 98% y fracción inspirada de oxígeno de 50%. Se realizó gasometría percutánea (arteria dorsal metatarsiana) tras 15 minutos de ser extubado el paciente y una segunda muestra arterial fue colectada 60 minutos luego de la instalación del dispositivo de alto flujo. Se observó un aumento de la presión parcial de oxígeno (PaO2) sin cambios en la presión parcial de dióxido de car- bono (PaCO2). Adicionalmente, se reportó tolerancia satisfactoria al dispositivo por parte de ambos pacientes. Las cánulas de alto flujo deben ser consideradas dentro de las estrategias de soporte ventilatorio no invasivo durante la posextubación en pacientes sometidos a cirugías de tórax.

- Abstract
Background: Eye-related neoplasms in dogs have a significant impact on visual ability, comfort, and longevity. Therapeutic alternatives and prognosis vary according to type of neoplasm and its anatomical location. Objective: To describe the frequency and distribution of eye-related neoplasms affecting dogs in Aburrá valley (Antioquia province, Colombia). Methods: A retrospective collection of eye-related neoplasms in dogs, diagnosed at the Animal Pathology Laboratory of Universidad de Antioquia (Colombia), was conducted. Data spanning from years 2005 to 2017 were used. Records included age, sex, breed, neoplasm type and location, and cellular origin of neoplasm. A total of 250 eye-related-neoplasm reports affecting 246 dogs were analyzed -one report per animal, with the exception of four animals with both eyes simultaneously affected by the same type of neoplasm. Results: Animals between 8 and 11 years of age were more frequently affected by eye-related neoplasms (43.9%). Labrador retriever (19.1%), mixed-breed dogs (13.4%), and Poodle (12.2%) were the most frequently affected breeds. Neoplasms affected the eyelid in 76.8% of cases. Meibomian gland adenoma was the most frequent neoplasm (22.8%), followed by Meibomian gland epithelioma (20.0%), squamous cell carcinoma (8.8%), and melanocytoma (7.2%).

- Abstract
Mycobacterium avium subsp. paratuberculosis (MAP) is an acid-fast, gram-positive bacillus. MAP is the causal agent of paratuberculosis (PTB) or Johne’s disease, an infectious disease affecting domestic ruminants and some wild species. Its importance as a potentially zoonotic agent due to its relation to Crohn’s disease (CD) in humans is still under debate and investigation. The aim of the present systematic review is to summarize original studies on MAP carried out in Colombia since 1924, as well as to establish strengths, weaknesses, and future research opportunities in the country with emphasis on diagnosis and epidemiology. The initial search for existing publications reporting original studies on MAP, PTB, and the relationship between MAP and CD was carried out in the available databases and national libraries. After compilation of the available studies (n = 20), the relevant data was extracted (year, province of report, species studied, diagnostic tests used, study design, summary of results, and authors). Recommendations for future research opportunities on MAP in Colombia are made., Resumo Mycobacterium avium subsp. paratuberculosis (MAP) é um ácido forte, bacilo gram-positivo. O MAP é o agente causador da paratuberculosis (PTB) ou doença de Johne, uma doença infecciosa que afecta os ruminantes domésticos e algumas espécies selvagens. Sua importância como um agente zoonótico por causa de sua relação com a doença de Crohn (CD) em humanos ainda está em discussão e sob investigação. O objetivo desta revisão é apresentar a estudos mapa original realizado na Colômbia desde 1924, e estabelecer pontos fortes, pontos fracos e oportunidades para futuras pesquisas no país com ênfase no diagnóstico e epidemiológico pontos de vista. A busca inicial da literatura sobre estudos originais sobre MAP, PTB e a relação MAP e CD foi feita nas bases de dados disponíveis e bibliotecas nacionais. Após a compilação dos estudos disponíveis (n = 20), os dados relevantes foram extraídos (ano, relatório província, espécies estudadas, teste de diagnóstico utilizado, desenho do estudo, os resultados resumo e autores). Foram feitas recomendações sobre futuras oportunidades de pesquisa em MAP em Colômbia., Resumen Mycobacterium avium subsp. paratuberculosis (MAP) es un bacilo ácido resistente, gram-positivo. MAP es el agente causal de la paratuberculosis (PTB) o enfermedad de Johne, una enfermedad infecciosa que afecta rumiantes domésticos y algunas especies salvajes. Su importancia como agente zoonótico, debido a su relación con la enfermedad de Crohn (CD) en humanos, está aún en debate y bajo investigación. El objetivo de la presente revisión es exponer los estudios originales sobre MAP llevados a cabo en Colombia desde 1924, así como establecer sus fortalezas, debilidades y oportunidades de investigación futura, con énfasis en los puntos de vista diagnóstico y epidemiológico.

Background: paratuberculosis is a slow-developing infectious disease, characterized by chronic granulomatous enterocolitis. This disease has a variable incubation period from 6 months to over 15 years, and is caused by Mycobacterium avium subsp. paratuberculosis (MAP). Its detection by direct and indirect diagnostic techniques has been of special interest. Objective: to report the diagnosis and detection of MAP using several diagnostic tests in a herd of the Northern region of Antioquia, Colombia. Methods: serum samples from the study herd were analyzed, using a commercial ELISA (enzyme-linked immunosorbent assay) kit. Fecal samples were cultured by duplicate using Herrold´s egg yolk medium (HEYM), and analyzed by an end- point IS900-specific nested PCR protocol, and a commercial F57-real-time PCR kit. Results: eight out of 27 serum samples in the study herd resulted ELISA-positive. None of fecal samples resulted positive to HEYM culture by duplicate and none were found to be positive by F57-real-time PCR. Seven of the 27 fecal samples were found to be positive by end-point IS900-specific nested PCR. Agreement was found between ELISA and end-point IS900-specific nested PCR in one of the animals. Conclusion: the present study gives information about the agreement between direct and indirect MAP-detection techniques, using different matrixes from animals under the same husbandry conditions. Resumen Antecedentes: la paratuberculosis es una enfermedad infecciosa de desarrollo lento, caracterizada por una enterocolitis granulomatosa crónica. Esta enfermedad tiene un periodo de incubación que varía entre los 6 meses hasta por más de 15 años, y es causada por Mycobacterium avium subsp. paratuberculosis (MAP). Su detección por técnicas diagnósticas directas e indirectas ha sido de interés especial. Objetivo: reportar el diagnóstico y detección de MAP utilizando varias técnicas diagnósticas en un hato de la región norte de Antioquia, Colombia. Métodos: se analizaron las muestras de suero del hato de estudio utilizando un kit comercial de ELISA (enzyme-linked immunosorbent assay). Las muestras de materia fecal fueron cultivadas por duplicado en Herrold´s egg yolk medium (HEYM), y analizadas mediante un protocolo de PCR anidado específico de IS900 y un kit comercial de PCR en tiempo real para F57. Resultados: ocho de las 27 muestras de suero resultaron positivas por ELISA. Ninguna de las muestras de materia fecal resultó positiva al cultivo en HEYM por duplicado ni por PCR en tiempo real para F57. Siete de las 27 muestras de materia fecal resultaron positivas a PCR anidado específico de IS900. Se encontró concordancia entre el resultado de ELISA y de PCR anidado específico de IS900 en uno de los animales. Conclusión: el presente estudio brinda información acerca de la concordancia entre técnicas directas e indirectas de detección de MAP, utilizando diferentes matrices a partir de animales bajo las mismas condiciones de manejo. Resumo Antecedentes: a paratuberculosis é uma doença infecciosa de evolução lenta, caracterizada por uma enterocolite granulomatosa crônica. Esta doença tem um período de incubação que varia de 6 meses a 15 anos e é causada pelo Mycobacterium avium subsp. paratuberculosis (MAP). Sua detecção por técnicas de diagnóstico diretos e indiretos tem sido de especial interesse. Objetivo: reportar o diagnóstico e a detecção de MAP utilizando várias técnicas de diagnóstico em um rebanho na região norte de Antióquia, Colômbia. Métodos: foram analisadas amostras de soro do rebanho utilizando um kit comercial de ELISA (enzyme- linked immunosorbent assay). As amostras de fezes foram cultivadas em duplicado em Herrold´s egg yolk medium (HEYM) e analisadas utilizando um protocolo de PCR aninhada específico de IS900 e um kit de PCR em tempo real comercial para F57. Resultados: oito das 27 amostras de soro foram positivas para ELISA. Nenhuma das amostras testadas na cultura de fezes HEYM duplicado foram positivas ou na PCR em tempo real para F57. Sete das 27 amostras de fezes foram positivas na PCR aninhada específica para IS900. Foi encontrada concordância entre o resultado de ELISA e PCR aninhada específica para IS900 em um animal. Conclusão: este estudo fornece informações sobre a correlação entre técnicas de detecção direta e indireta do MAP, utilizando diferentes matrizes de animais sob as mesmas condições de condução.

Summary Background: Johne´s disease (JD) is a severe enteritis that affects ruminants and has been diagnosed in cattle and sheep in Colombia. However, epidemiological information on the disease in this country is scarce. Objective: to identify factors associated with the JD serum enzyme-linked immunosorbent assay (ELISA) status of dairy cows. Methods: a cross-sectional study was carried out in 307 asymptomatic adult Holstein dairy cows from 14 herds in nine districts of Belmira and San Pedro de los Milagros municipalities during November, 2007. From 19 to 25 cows, ≥ 2 years of age were randomly selected and blood sampled from every herd. A commercial ELISA kit was used to analyze sera. Information regarding cow related factors (age, farm-born, parity, and daily milk yield) and herd management practices (i.e. herd size, herd average milk production, current presence of symptomatic animals, cattle purchase, own animals grazing in foreign pastures, feeding of calves before weaning, manure spread on pastures, and sighting of birds in feed storing areas) was collected using questionnaires.

Descriptive statistics were computed for all variables and a multivariable logistic regression model was constructed (p<0.05). Results: ten percent (31/307; 95% CI: 7.0-14.0%) of the animals were positive by ELISA. In 70% (10/14) of the herds, ELISA detected at least one positive animal. Cow and herd factors “parity” and “feeding of calves before weaning” showed weak and strong associations with ELISA positive results, respectively. The odds ratio (OR) for JD seropositivity increased 20% (OR = 1.20; 95% CI: 0.98-1.47; p = 0.067) in cows with > 1 parity. The OR was 0.74 times lower (OR = 0.26; 95% CI: 0.096-0.70; p<0.01) in herds feeding calves with pooled colostrum from several cows, compared to herds feeding calves with colostrum from their own dams.

Resultados: oito das 27 amostras de soro foram positivas para ELISA. Nenhuma das amostras testadas na cultura de fezes HEYM duplicado foram positivas ou na PCR em tempo real para F57. Sete das 27 amostras de fezes foram positivas na PCR aninhada específica para IS900. Foi encontrada concordância entre o resultado de ELISA e PCR aninhada específica para IS900 em um animal. Conclusão: este estudo fornece informações sobre a correlação entre técnicas de detecção direta e indireta do MAP, utilizando diferentes matrizes de animais sob as mesmas condições de condução., Resumen Antecedentes: la paratuberculosis es una enfermedad infecciosa de desarrollo lento, caracterizada por una enterocolitis granulomatosa crónica. Esta enfermedad tiene un periodo de incubación que varía entre los 6 meses hasta por más de 15 años, y es causada por Mycobacterium avium subsp. paratuberculosis (MAP). Su detección por técnicas diagnósticas directas e indirectas ha sido de interés especial. Objetivo: reportar el diagnóstico y detección de MAP utilizando varias técnicas diagnósticas en un hato de la región norte de Antioquia, Colombia. Métodos: se analizaron las muestras de suero del hato de estudio utilizando un kit comercial de ELISA (enzyme-linked immunosorbent assay). Las muestras de materia fecal fueron cultivadas por duplicado en Herrold´s egg yolk medium (HEYM), y analizadas mediante un protocolo de PCR anidado específico de IS900 y un kit comercial de PCR en tiempo real para F57. Resultados: ocho de las 27 muestras de suero resultaron positivas por ELISA. Ninguna de las muestras de materia fecal resultó positiva al cultivo en HEYM por duplicado ni por PCR en tiempo real para F57. Siete de las 27 muestras de materia fecal resultaron positivas a PCR anidado específico de IS900. Se encontró concordancia entre el resultado de ELISA y de PCR anidado específico de IS900 en uno de los animales. Conclusión: el presente estudio brinda información acerca de la concordancia entre técnicas directas e indirectas de detección de MAP, utilizando diferentes matrices a partir de animales bajo las mismas condiciones de manejo.

Background: paratuberculosis is a slow-developing infectious disease, characterized by chronic granulomatous enterocolitis. This disease has a variable incubation period from 6 months to over 15 years, and is caused by Mycobacterium avium subsp. paratuberculosis (MAP). Its detection by direct and indirect diagnostic techniques has been of special interest. Objective: to report the diagnosis and detection of MAP using several diagnostic tests in a herd of the Northern region of Antioquia, Colombia. Methods: serum samples from the study herd were analyzed, using a commercial ELISA (enzyme-linked immunosorbent assay) kit. Fecal samples were cultured by duplicate using Herrold's egg yolk medium (HEYM), and analyzed by an endpoint IS900-specific nested PCR protocol, and a commercial F57-real-time PCR kit. Results: eight out of 27 serum samples in the study herd resulted ELISA-positive. None of fecal samples resulted positive to HEYM culture by duplicate and none were found to be positive by F57-real-time PCR. Seven of the 27 fecal samples were found to be positive by end-point IS900-specific nested PCR. Agreement was found between ELISA and end-point IS900-specific nested PCR in one of the animals. Conclusion: the present study gives information about the agreement between direct and indirect MAP-detection techniques, using different matrixes from animals under the same husbandry conditions.

- Abstract
Introduction: Rabies virus infection can cause fatal brain disease in mammals. Any species is susceptible to infection. Any effort aimed at recognizing infected animals and performing first actions in the event of transmission is mandatory., Objective: To determine knowledge, attitudes, and practice profiles regarding rabies, or hydrophobia, in a municipality of Colombia, using a multiple correspondence analysis., Materials and Methods: A descriptive observational study involving 71 pet owners was carried out in the municipality of Ibagué (Tolima). A questionnaire-based survey collected data on rabies knowledge, attitudes, practices, and demographic information. The survey was conducted between October and November 2021, and the data analysis involved descriptive statistics and multiple correspondence analysis., Results: The study revealed a commendable level of rabies awareness among the urban residents in the study municipality. However, there are causes of concern as they allow stray animals to enter their homes and are not aware of the importance of notifying dead animals. The respondents demonstrated a humane approach to bite management and emphasized the importance of wound cleaning. Additionally, they expressed a strong desire for more information to enhance their knowledge and awareness of the disease., Conclusion: The findings of this study provide valuable insights for improving rabies prevention efforts and promoting public health. Health education, evidence-based strategies, and community participation are essential for successful disease control and educational gaps addressing related to sociocultural factors.
