RESUMEN

En el siguiente informe se describe un caso de aborto bovino asociado a neosporosis en México. El feto fue remitido para su estudio al Departamento de Patología de la Facultad de Medicina Veterinaria y Zootecnia de la Universidad Nacional Autónoma de México. El feto fue expulsado al quinto mes de gestación, siendo macho y de raza Holstein. En el estudio microscópico se encontró encefalitis no supurativa con múltiples focos de necrosis y gliosis, además de un quiste parasitario oval de pared gruesa de 21 X 22 mm. Varias secciones de tejido nervioso desparafinadas se examinaron para estudio inmunohistoquímico, utilizando anticuerpos anti Neospora caninum encontrándose grupos de taquizoitos extracelulares asociados a las áreas de gliosis. También se encontró miocarditis y hepatitis no supurativa discreta. Se cree que este es el primer caso descrito en Méxcico de aborto bovino asociado a lesiones características y a la presencia de estructuras parasitarias correspondientes a Neospora sp. Sin embargo, es necesario realizar más estudios anatomopatológicos e inmunológicos para poder determinar la prevalencia y la significancia de aborto bovino asociado a neosporosis en México.
