Algunos años atrás, luego de una revisión taxonómica, se demostró que el género Isospora representa a aquellas especies cercanas a Eimeriidae (Barta et al., 2005). Las especies que afectan a perros y gatos se incluyen desde entonces en el género Cystoisospora. Éstas son especies parásitas de carnívoros y se relacionan con otros géneros —Hammondia, Toxoplasma, Besnoitia y Sarcocystis—presentando ooquistes esporulados similares, y utilizando a los carnívoros y omnívoros como hospedadores definitivos. Sin embargo, en este capítulo se mantendrá el nombre tradicional (Isospora) para todas las especies de coccidios intestinales que afectan a los pequeños animales (Cordero del Campillo et al., 1999; Melnhorn, 2008)., Facultad de Ciencias Veterinarias, Facultad de Ciencias Naturales y Museo

INTRODUCCIÓN: Los roedores sinantrópicos, representados por el ratón doméstico (Mus musculus), la rata parda (Rattus norvegicus) y la rata negra (Rattus rattus), representan un riesgo importante para la salud. En Sudamérica, la fragmentación socioeconómica se refleja en marcadas diferencias entre centros urbanos y áreas periféricas, y se asocia a un registro heterogéneo. El objetivo fue relevar datos por encuestas a los habitantes de dos barrios del Gran La Plata con características contrastantes para explorar, describir y evaluar la percepción en relación con la presencia de roedores en domicilio, peridomicilio y barrio como vehículos de transmisión de enfermedades. MÉTODOS: A partir de un diseño descriptivo exploratorio, se confeccionaron y realizaron encuestas siguiendo la técnica de muestreo estratificado. Se consideraron las variables género y grupo, de tal manera que la muestra tuviese la misma distribución. La información se transfirió a una base de datos y se analizó a través de IBM SPSS Statistics V25. RESULTADOS: Existe una preocupación común respecto al rol de los roedores urbanos como reservorios y fuentes de infección de patologías zoonóticas. En el barrio más vulnerable, la presencia de roedores fue más frecuente que en el centro de la ciudad. DISCUSIÓN: Este estudio provee un abordaje diferente en relación con roedores y patologías asociadas, considerando la percepción social y revelando su importancia para los programas de manejo y control., INTRODUCTION: Synanthropic rodents, which are represented by house mouse (Mus musculus), Norway rat (Rattus norvegicus) and black rat (Rattus rattus), pose a high health risk. In South America, socioeconomic fragmentation generates marked differences between urban centers and peripheral areas and are associated with a heterogeneous record. The objective was to gather data by surveying inhabitants of two neighborhoods with contrasting features in Greater La Plata, province of Buenos Aires, in order to explore, describe and evaluate the perception on the presence of rodents in domicile, peridomicile and neighborhood as vehicles of disease transmission. METHODS: An exploratory descriptive design was used to make and conduct surveys following the technique of stratified sampling. The variables gender and group were considered to have the same distribution in the sample. The information was transferred to a database and analyzed through IBM SPSS Statistics V25. RESULTS: There is a common concern related to the role played by urban rodents as reservoirs and source of infection of zoonotic pathologies. The presence of rodents in the most vulnerable neighborhood was higher than in the center of the city. DISCUSSION: This study provides a different perspective related to rodents and pathologies associated, considering social perception and showing its importance for management and control programs., Centro de Estudios Parasitológicos y de Vectores

Big cities of Argentina are characterized by a strong social and economic fragmentation. This context enables the presence of urban rodents in close contact to the human population, mostly in the peripheral areas of the cities. Urban rodents can harbor a large variety of zoonotic pathogens. The aim of this study was to molecularly characterize Leptospira spp. and Bartonella spp. in urban rodents from the area of Gran La Plata, Buenos Aires province, Argentina. The species of urban rodents captured and tested were Rattus norvegicus, Rattus rattus, and Mus musculus. Leptospira interrogans and L. borgpetersenii were detected in R. norvegicus and M. musculus respectively. Bartonella spp. DNA was not detected in any of the kidney samples tested. No significant differences were observed between the prevalence of bacteria and rodent and environmental variables such as host sex, presence of stream and season by Generalized Linear Model analysis. These results confirm the role of urban rodents as infection sources of Leptospira spp., suggesting the need to implement public health measures to prevent the transmission of Leptospira spp. and other zoonotic pathogens from rodents to humans. Bartonella was not detected in this set of samples. [ABSTRACT FROM AUTHOR]

Toxoplasma gondii and Neospora caninum are closely related coccidian parasites (phylum Apicomplexa). This is the first study from urban synanthropic rodent species that involved serological and molecular diagnosis of T. gondii and N. caninum infection, and genotyping of T. gondii in Argentina. A total of 127 rodent samples were trap captured: Mus musculus (n = 78), Rattus norvegicus (n = 26) and Rattus rattus (n = 23). Antibodies against T. gondii and N. caninum were detected by IFAT in 32.8% (40/122) and 0.8% (1/122) of rodent samples, respectively, demonstrating contact with these protozoans. Additionally, T. gondii DNA was detected in 3.3% (4/123) of rodent central nervous system samples and 2 samples were genotyped by multilocus nPCR-RFLP. Neospora caninum DNA was not detected by PCR. The 2 genotyped samples were type III allele for all markers except for SAG-1 (type I for Rat1Arg and type II/III for Rat2Arg) and were identified as #48 and #2 (likely) according to the allele combinations reported on Toxo DB (Toxo-DB). The results of the present study revealed a wide distribution of T. gondii and less for N. caninum, in synanthropic rats and mice in the studied area., Toxoplasma gondii e Neospora caninum são parasitas coccídeos intimamente relacionados (filo Apicomplexa). Este é o primeiro estudo de espécies de roedores sinantrópicos urbanos, o qual envolveu diagnósticos sorológicos e moleculares da infecção por T. gondii e N. caninum e genotipagem de T. gondii na Argentina. Um total de 127 amostras de roedores foram obtidas: Mus musculus (n = 78), Rattus norvegicus (n = 26) e Rattus rattus (n = 23). Anticorpos contra T. gondii e N. caninum foram detectados pela IFAT em 32,8% (40/122) e 0,8% (1/122) das amostras de roedores, respectivamente, demonstrando contato com esses protozoários. Adicionalmente, o DNA de T. gondii foi detectado em 3,3% (4/123) das amostras do sistema nervoso central de roedores e duas amostras foram genotipadas por nPCR-RFLP multilocus. O DNA de N. caninum não foi detectado por PCR. As 2 amostras genotipadas eram do tipo III para todos os marcadores, exceto para SAG-1 (tipo I para Rat1Arg e tipo II / III para Rat2Arg) e foram identificadas como # 48 e # 2 (provavelmente) de acordo com as combinações de alelos relatadas no Toxo DB (Toxo-DB). Os resultados do presente estudo indicam uma ampla distribuição de T. gondii e menor para N. caninum, em ratos e camundongos sinantrópicos na área estudada., Facultad de Ciencias Veterinarias, Centro de Estudios Parasitológicos y de Vectores

The main purpose of this study was to characterize the helmintological fauna of three commensal rodents from Argentina, with the final goal of finding Strobilocercus fasciolaris (Cestoda: Cyclophyllidea), discussing possible reasons of the maintenance of the cycle in the study areas. Strobilocercus fasciolaris was observed in all the studied rodent species, including Rattus rattus and Mus musculus, which constitute new host records in Argentina. Estimates of prevalence, mean abundance and mean intensity were provided, and the existing morphometric characterization of the parasite was supplemented. Significant differences of prevalence between R. norvegicus and M. musculus and among seasons were observed. The potential risk of zoonotic transmission of S. fasciolaris is suggested., El objetivo de este estudio fue identificar la fauna helmintológica de las tres especies de roedores comensales de Argentina, con el fin de hallar Strobilocercus fasciolaris, y discutir las posibles razones del mantenimiento del ciclo de vida en las áreas involucradas. Strobilocercus fasciolaris fue observado en todas las especies de roedores, incluyendo Rattus rattus y Mus musculus, que constituyen nuevos registros hospedatorios en Argentina. Se brindan los valores de prevalencia, abundancia media e intensidad media y se complementa la caracterización morfométrica de la especie. Fueron observadas diferencias significativas entre la prevalencia y estaciones del año de captura de Rattus norvegicus y M. musculus. Se sugiere un riesgo potencial de transmisión zoonótica de S. fasciolaris., Facultad de Ciencias Naturales y Museo
