Considerada um agravo a saúde por se tratar de uma zoonose e de grande importância na rotina clínica médica de pequenos animais, a Erliquiose Monocítica Canina pode causar febre e diarreia, além de desordens no sistema neurológico e renal. Sendo assim, tendo em vista a relevância clínica da patologia, objetivou-se identificar o números de casos ocorridos na cidade de Barreiras, Oeste da Bahia, durante o período de Janeiro a Dezembro de 2018, relacionando-os a condições climáticas presentes em determinados intervalos, raças em que a incidência de casos se manifestou de uma forma mais eminente, além do sexo e idade dos cães acometidos, estabelecendo assim, diferentes causas. Foi constatado a partir de um estudo epidemiológico, mais de 140 diagnósticos, com superior acometimento durante o período chuvoso, de fêmeas sem raça definida, entre 1 a 5 anos de idade. É imprescindível nos atentarmos ao que diz respeito a profilaxia, visando diminuir o número de casos e intensificar o bem-estar animal.

A agenesia da veia cava caudal é uma malformação que ocorre ainda no período da embriogênese, tendo como característica a ausência parcial ou total do órgão. Por se tratar de uma anormalidade às vezes assintomática, são achados raros encontrados em exames de imagem, podendo ser desde uma simples ultrassonografia, a uma tomografia computadorizada, sendo os mesmos os principais métodos para a detecção e fechamento do diagnóstico. Este trabalho tem como objetivo relatar um caso de um cão da raça Scott Terrier, de 8 anos e 4 meses, atendido em um hospital veterinário na cidade de Salvador-BA, que após a realização de ultrassom e tomografia, confirmou-se a agenesia da veia cava caudal.

Background Phylogenetic studies indicate bats as original hosts of SARS-CoV-2. However, it remains unclear whether other animals, including pets, are crucial in the spread and maintenance of COVID-19 worldwide. Methods In this study, we analyzed the first fatal case of a SARS-CoV-2 and FeLV co-infection in an eight-year-old male cat. We carried out a clinical evaluation and several laboratory analyses. Results As main results, we observed an animal presenting severe acute respiratory syndrome and lesions in several organs, which led to the animal’s death. RT-qPCR analysis showed a SARS-CoV-2 as the causative agent. The virus was detected in several organs, indicating a multisystemic infection. The virus was found in a high load in the trachea, suggesting that the animal may have contribute to the transmission of the virus. The whole-genome sequencing revealed an infection by SARS-CoV-2 Gamma VOC (P.1), and any mutations indicating host adaptation were observed. Conclusion Our data show that FeLV-positive cats are susceptible to SARS-CoV-2 infection and raise questions about the potential of immunocompromised FeLV-positive cats to act as a reservoir for SARS-CoV-2 new variants.

Background: Coronaviruses are recognized for their ability to cross the species barrier and infect new hosts. The coronavirus disease 2019 (COVID-19) is caused by the new coronavirus SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2). It remains unclear whether other animals, including pets, are crucial in the spread and maintenance of COVID-19 worldwide. Methods: In this study, we analysed the first fatal case of a SARS-CoV-2 and FeLV (Feline leukemia virus) co-infection of an eight-year-old male cat. We carried out a clinical evaluation, pathological analysis, and viral genomic analysis. Results: As main results, we observed an animal presenting severe acute respiratory syndrome and lesions in several organs, which led to animal’s death. The causative agent was confirmed to be SARS-CoV-2, variant of concern P.1 (Gamma). The virus presented a pattern of mutations potentially associated with feline infection. In addition, the virus was detected by RT-qPCR in the spleen, liver, heart, lungs, trachea, intestines and kidneys, indicating a multisystemic viral infection. The virus was found in a high load in the trachea, suggesting a capacity of transmitting the virus. Conclusion: Our data show that felines, such as FeLV-positive cats, are susceptible to SARS-CoV-2 infection, and may be intermediate hosts in this pandemic.

Therefore, sixteen piglets weighing 16±1.1kg, were randomly divided into two groups: GI (Isoflurane and FIO2 of 0.5) and GP (Propofol and FIO2 of 0.5). Heart rate (HR), systolic, diastolic and mean arterial pressure (SAP, DAP and MAP), central venous pressure (CVP), cardiac output (CO), mean pulmonary arterial pressure (mPAP) and mean capillary pulmonary pressure (mCPP) were assessed 40 minutes after anesthetic induction (T0), followed by 15 minutes intervals (from T15 to T60). The variables cardiac index (CI), stroke volume (SV), stroke index (SI), total peripheral resistance (TPR), total peripheral resistance index (TPRI), pulmonary vascular resistance (PVR), and pulmonary vascular resistance index (PVRI) were calculated. SAP and TPRI were significantly different between groups at T30 and T60 (P< 0.05) with higher GP values being recorded. There were no differences in the other variables, however, GP presented mean closer to normality on most of the analyzed variables. Therefore, we conclude that total intravenous anesthesia with propofol presented greater stability of the hemodynamic variables evaluated.

The effects of different concentrations of oxygen and nitrous oxide on blood gas parameters in pigs maintained under spontaneous or pressure-controlled ventilation, with or without positive end-expiratory pressure (PEEP), were compared. Forty-eight pigs were randomly divided into six groups, submitted to different concentrations of compressed air or N2O, associated with different fractions of inspired oxygen (FiO2). The group subject to 30% of compressed air (GA30) showed the closest proximity to the physiological range of partial pressure (PaO2) expected for the species. For oxygen saturation (SaO2), the values obtained were below the lower physiological limit in the group administered 30% N2O (GN30). Use of PEEP positively interfered in PaCO2 independent of FiO2, however, its effectiveness can be compromised when complemented by N2O-based anesthesia. For SaO2, only GN30 showed values lower than adequate for maintaining tissue oxygenation. The pH, base deficit and bicarbonate in arterial blood were influenced by FiO2 and N2O. In conclusion, the use of compressed air maintains blood gas parameters at their most stable, especially GA30 and PEEP, which seemed to positively influence the experimental groups, with some interference from FiO2 and N2O. RESUMO Compararam-se os efeitos de diferentes concentrações do óxido nitroso ou oxigênio sobre variáveis hemogasométricas, em suínos mantidos em ventilação espontânea ou controlada à pressão, associada ou não à pressão expiratória final positiva (PEEP). Foram utilizados 48 porcos, distribuídos em seis grupos. Administraram-se diferentes concentrações de ar comprimido ou N2O, associadas a diversas frações de oxigênio inspirado (FiO2). O grupo sujeito a 30% de ar comprimido (GA30) mostrou maior proximidade do intervalo fisiológico da pressão parcial de oxigênio (PaO2). Para a saturação de oxigênio (SaO2), observaram-se valores aquém do limite inferior fisiológico no grupo administrado com 30% de N2O (GN30). A utilização da PEEP é capaz de interferir positivamente na PaCO2, independentemente da FiO2, porém tem a efetividade comprometida quando há complemento da anestesia com o N2O. Para a SaO2, apenas o GN30 esboçou valores inferiores aos adequados para manutenção da oxigenação tecidual. O pH, o déficit base e o bicarbonato no sangue arterial foram influenciados pela FiO2 e pelo N2O. Concluiu-se que o uso do ar comprimido mantém os parâmetros hemogasométricos mais estáveis, com destaque para o GA30 e a PEEP, o que parece influenciar positivamente os grupos experimentais, mas com interferência da FiO2 e do N2O.

Avaliaram-se os efeitos nos parâmetros ventilometricos e hemogasometricos em cadelas submetidas a ovariohisterectomia (OHE), pre-medicadas com tramadol ou morfina e anestesiadas com isofluorano. Utilizaram-se 12 cadelas sem raca definida (SRD), divididas em dois grupos (n= 6 para cada grupo), todas com inducao anestesica com propofol e manutencao com isofluorano em O 2 a 100%, sendo que a diferenca entre os grupos se deu pela pre-medicacao com tramadol (GT – 4mg/Kg IM) ou morfina (GM – 0,4 mg/Kg IM). As observacoes das variaveis iniciaram-se 30 minutos apos a administracao do bolus de propofol (M0). As demais colheitas dos dados foram realizadas em intervalos de 15 minutos, por um periodo de 60 minutos (M15, M30, M45 e M60, respectivamente). Nao foram encontradas diferencas significativas entre os grupos ou momentos para as variaveis hemogasometricas, entretanto os medias de pH, deficit de base (DB) e pressao parcial de dioxido de carbono no sangue arterial (PaCO 2 ) ficaram fora da faixa normal para a especie canina. Foram encontradas diferencas significativas para as variaveis: volume corrente (GM > GT de M0 a M60), pico de fluxo inspiratorio e expiratorio (GM > GT) e pressao de pico inspiratorio, sendo que GM foi maior que GT em M0. Concluiu-se que ambos os opioides sao seguros, nao causando alteracoes importantes na ventilometria quando utilizados na pre-medicacao em cadelas anestesiadas com isofluorano e submetidas a OHE, porem, a anestesia inalatoria com isofluorano deve ser utilizada com cautela em animais com propensao a acidemia.

Distribuíram-se 28 coelhos nos grupos: GIVC (isofluorano e ventilação controlada a volume), GIVE (isofluorano e ventilação espontânea), GSVC (sevofluorano e ventilação controlada a volume) e GSVE (sevofluorano e ventilação espontânea). Induziu-se por máscara, com isofluorano (GIVE e GIVC) ou sevofluorano (GSVE e GSVC) a 1,5 CAM, em oxigênio a 100%. Para manutenção anestésica, reajustou-se para 1 CAM. No GIVC e no GSVC, administrou-se rocurônio, na dose de 0,6mg/kg, seguida de infusão contínua na mesma dose de 0,6mg/kg/h. No GIVE e no GSVE, foi administrado NaCl 0,9% em vez de rocurônio. Iniciou-se a ventilação controlada ajustando-a de maneira a obter capnometria entre 35 e 45mmHg. Mensuraram-se os parâmetros 60 minutos após a indução anestésica (M0), 15 minutos após o bolus de rocurônio ou NaCl 0,9% (M15) e a cada 15 minutos (M30, M45 e M60). Evidenciou-se hipercapnia e acidose em GIVC, GSVC e GSVE. Concluiu-se que a ventilação mecânica controlada a volume não foi capaz de manter a normocapnia em coelhos, gerando acidose, principalmente quando se utilizou sevofluorano. O uso do isofluorano demonstrou maior estabilidade anestésica que o sevofluorano nesta. The volume-controlled mechanical ventilation and spontaneous ventilation, through haemogasometric, cardiovascular and spirometry variables were evaluated. Twenty-eight rabbits were distributed into two groups: GIVC (isoflurane and volume-controlled ventilation), GIVE (isoflurane and spontaneous ventilation), GSVC (sevoflurane and volume-controlled ventilation) and GSVE (sevoflurane and spontaneous ventilation). Induction was performed by mask with isoflurane (GIVE and GIVC) or sevoflurane (GSVE and GSVC) at 1.5 MAC in 100% oxygen. To maintain anesthesia, MAC was reset to 1. In GIVC and GSVC groups, rocuronium was administered at a dose of 0.6 mg/kg followed by its continuous infusion (0.6 mg/kg/h). In GSVE and GIVE, 0.9% NaCl was administered instead of rocuronium. Controlled ventilation was started by adjusting the capnometry in order to obtain values between 35 and 45 mmHg. Parameters were measured 60 minutes after induction of anesthesia (M0), 15 minutes after the bolus of rocuronium or 0.9% NaCl (M15) and every fifteen minutes (M30, M45 and M60). Hypercapnia and acidosis was evident in GIVC, GSVC and GSVE. We concluded that the volume-controlled mechanical ventilation was not able to maintain normocapnia in rabbits, producing acidosis in them, especially when using sevoflurane. The use of isoflurane showed greater stability than the sevoflurane anesthetic in the species studied.

Odontogenics tumors are uncommon in the dog. Ameloblastoma is considered a benign, aggressive and non-inductive odontogenic neoplasia commonly located in the incisor teeth. Its conclusive diagnosis is obtained by histopathological examination. Due to the expansive nature of this neoplasia, its resection needs to have an adequate surgical margin so it will have excellent prognostics. A canine, male, Pekingese, 8 years old had an increased volume in the rostral region of the mandible, adhered, consistency moderately firm. Radiography revealed extensive mandibular bone lysis caused by the neoplasia. Biopsy identified the tumor as ameloblastoma. Combining data from the clinical, radiographic and histopatological study and after explain to the owner regarding the postoperative esthetic it was held a bilateral rostral mandibulectomy. The fragment removed was assessed radiographically and histopathologically for evidence of tumor at its edges. The patient is active and healthy without evidence of metastasis or recurrence. The radiographic and histopathologic evaluation of edges of the fragment showed no tumor evidence. The patient is active and healthy without evidence of metastasis or recurrence since January 2010 when mandibulectomy was performed.Os tumores odontogênicos são alterações incomuns no cão. O ameloblastoma é considerado uma neoplasia odontogênica benigna, agressiva e não indutiva, comumente localizada na região dos dentes incisivos. Seu diagnóstico conclusivo é obtido através do histopatológico. Devido ao caráter expansivo desta neoplasia uma ressecção com margem cirúrgica adequada é necessária para que se tenha um excelente prognóstico. Um canino, macho, Pequinês de oito anos apresentou um aumento de volume na região rostral da mandíbula, aderido e de consistência moderadamente firme. A radiografia mandibular demonstrou a extensão da lise óssea causada pela neoplasia. O estudo histopatológico identificou a alteração como ameloblastoma. Conciliando dados do exame clínico, estudo radiográfico e histopatológico e após o esclarecimento do proprietário a respeito da estética pós-operatória, foi realizada uma mandibulectomia rostral bilateral. A avaliação radiografica e histopatológica das bordas do fragmento não demonstraram indícios tumorais. O paciente se encontra ativo e saudável sem indícios de metástase ou recidiva desde janeiro de 2010, quando foi realizada a mandibulectomia.

Although injury to the metacarpophalangeal joint frequently occurs in this sport, there is limited information describing the nature of these injuries. The aim of this study was to determine the most common radiographic abnormalities in barrel racing horses with lameness referable to the metacarpophalangeal joint. lameness examinations were performed on 63 barrel racing horses. Those found to be lame were subjected to radiographic examination. Lameness at trot was scored on a scale of 0-5 (0 = sound; 5 = inability to move). Data were analyzed using descriptive statistical analysis. of horses examined, 30 (47.6%) were lame with scores ranging from 1 to 4. Half of the lame horses (15 of 30) had grade 2 lameness of the right forelimb. Abnormal radiographic findings were more often present on the left forelimb and included signs of sesamoiditis (70%), villonodular synovitis (56.6%), osteoarthritis (36.6%), osteochondritis dissecans (13.3%), capsulitis (13.3%), and soft-tissue swelling (6.6%). Radiographic abnormalities indicated that sesamoiditis, villonodular synovitis, and osteoarthritis may be associated to mild-to-moderate lameness in barrel racing horses. Complementary sonographic evaluation is recommended to better characterize soft-tissue abnormalities. (C) 2012 Elsevier B.V. All rights reserved.

La hipotermia transoperatoria es una complicación común en pacientes sometidos a anestesia general para procedimientos quirúrgicos. En este trabajo se evalúa el uso de un colchón térmico eléctrico como método de control de temperatura en 18 hembras caninas de aproximadamente seis meses de edad, sometidas a ovario-histerectomía (OVH) electiva, bajo anestesia general. Fueron evaluadas las constantes fisiológicas y los tiempos de recuperación, comparando tres grupos distribuidos aleatoriamente: G1, control, sin control de temperatura; G2, uso de colchón térmico a 38 °C durante el periodo trans y posoperatorio, y G3, control de temperatura de la misma manera pero solo en el periodo posoperatorio. El colchón térmico es una medida efectiva y segura para el control de la hipotermia perioperatoria mostrando mejores resultados cuando es usado en todos los momentos y no solo en el posoperatorio.

Foram usados 12 eqüinos adultos, clinicamente sadios e distribuídos aleatoriamente em dois grupos que receberam diferentes doses de colagenase. O grupo 1 (G1) recebeu 1,25mg e o grupo 2 (G2) recebeu 2,5mg de colagenase. Com a agulha posicionada no centro dos tendões flexores digitais superficiais dos membros torácicos, as diferentes doses de colagenase foram aplicadas conforme o grupo experimental. O acompanhamento das lesões tendíneas baseou-se em exames físicos e ultra-sonográficos, realizados a cada sete dias até o período de 28 dias pós-indução. Nas imagens ultra-sonográficas, foram avaliados os parâmetros ecogenicidade, percentual de área lesada, grau de redução e severidade das lesões do tendão flexor digital superficial. O parâmetro mais fiel em resposta às diferentes doses de colagenase administradas foi o percentual de área lesada no interior do tendão. O G2 apresentou uma melhor resposta ultra-sonográfica da tendinite do flexor digital superficial para a realização de estudos experimentais. In this study, tendinous injuries were induced experimentally in horses, through the administration of different doses of collagenase. Twelve horses, clinically healthy, were distributed into two groups that received different doses of collagenase. Group 1 (G1) received 1.25mg and Group 2 (G2) received 2.5mg of collagenase. With the needle positioned at the center of the superficial digital flexor tendon in the equine forelimbs, different doses of collagenase were applied in agreement the experimental group. The monitoring of colagenase-induced tendonitis was based on physical and ultrasonographic exams, carried out every seven days until the period of 28 days post-induction. In the images of ultrasound were evaluated the echogenicity, the percentage of injured area, degree of reduction and severity of injuries of colagenase-induced tendonitis. The most accurate parameter in response to different doses of collagenase administered was the percentage of area injured in the interior of the tendon. The G2 presented one better ultrasonographic reply of the tendonitis of the superficial digital flexor for the accomplishment of experimental studies.

A gastroduodenite ulcerativa crônica e os espasmos prolongados foram as supostas causas da hipertrofia da musculatura circular do piloro, causando a estenose. O tratamento com substâncias antiulcerativas é paliativo e o acesso cirúrgico ao piloro no animal adulto é complexo, sendo o prognóstico duvidoso. A case of hypertrophic pyloric stenosis diagnosed by gastroscopy was reported in a 4-years-old Quarter Horse gelding, with signs of inappetence, chronic weight loss, colic, bruxism and sialorrhea. Gastroduodenal ulceration and spasms were supposed as causes of pyloric muscular hypertrophy and stenosis. Antiulcerative medications are merely palliative and the complex surgical approach to the site of stenosis makes the prognostic to be doubtful.

Con el objetivo de evaluar las variaciones de la glucemia en caninos sometidos a hipotermia moderada se utilizaron ocho canes adultos, anestesiados con etomidato e isofluorano y sometidos a tres franjas de temperatura: 32-33 °C, 34-35 °C y normotermia 38,5 ± 1 °C, durante 150 min. La glucosa sérica de estos animales fue evaluada en el periodo basal y cada 30 min durante el periodo experimental. La glucemia fue mayor durante los 60, 90 y 120 min, comparada con las concentraciones basales; fue similar en las franjas de temperatura estudiadas y se mantuvo siempre dentro de los rangos para la especie. La aplicación de hipotermia moderada no altera las concentraciones de glucosa, lo que se constituye en un aspecto relevante en la neuroprotección.
