El estudio evaluó la acción antagonista in vitro de postbióticos, derivados de probióticos nativos de suri (Rhea pennata) frente a Escherichia coli asociado a enteritis bacteriana en suris. Las cepas probióticas aisladas, Lacticaseibacillus, Bacillus rugosus y Pichia ethanolica fueron obtenidas de 30 muestras de heces de suris en cautiverio aparentemente sanos. Los probióticos aislados fueron cultivados en solución de melaza al 5%, solos o en combinaciones para obtener los postbióticos. La prueba de inhibición se realizó mediante el método de difusión en agar Müeller-Hinton, empleando pozos perforados en el medio con cultivo de E. coli e inoculando 50 µL de los postbióticos filtrados a través de membranas con poros de 0.22 µm, obtenidos tanto de cultivos individuales como de combinaciones de dos y tres cepas probióticas. Se midieron los halos inhibitorios del crecimient...

Con el presente estudio se determinó el efecto de la persistencia de anticuerpos maternales contra Cisticercosis porcina sobre el EITB, después de haber analizado los resultados de 299 crías clasificados según el sexo, estado inmunológico de crías y sus madres. Estos resultados corresponden a una base de datos, de estudios epidemiológicos realizados en el distrito de Quilcas- Huancayo desde hace cuatro años, por los integrantes del Laboratorio de Medicina Veterinaria Preventiva de la Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos - Lima Perú. El tiempo de persistencia de anticuerpos maternales fue de 148.8 en promedio, con un rango de 117 a 242 días. Referente al sexo, se encontró que en machos permanecía 146 días y en las hembras 155 días, no encontrando diferencia estadística significativa. El tiempo promedio en que las crías de porcinos...

In order to describe bovine neosporosis as a livestock health problem in the Andes, the determinants, epidemiology and control of this parasitosis were identified, for this purpose a review of the literature published in the ScienceDirect collection was made, finding that the canine is the main determinant for bovine neosporosis, as a propagator in the stable of the protozoan Neospora caninum, other factors are related to the components of the production system and cattle breeds; It was observed that horizontal transmission of bovine neosporosis occurs through dog excreta contaminating cattle feed and vertical transmission occurs in young cows with low immunity, thus affecting their offspring, with fetuses being infected by N. caninum, causing abortions or reproductive problems such as return to estrus or temporary loss of estrus, a situation that causes important economic losses for cat...
