Neospora caninum en llamas de Huancavelica, Perú

Abstract

El objetivo del presente estudio fue determinar, mediante la técnica de Inmunofluorescencia Indirecta (IFI), la frecuencia de anticuerpos frente a Neospora caninum en llamas de la comunidad ganadera de Lachocc, Huancavelica. Se tomó muestras de sangre de 98 llamas hembras adultas, mayores de un año. Los sueros se analizaron mediante IFI empleando un punto de corte de 1:100. Los sueros positivos fueron titulados con diluciones seriadas, determinándose una frecuencia de anticuerpos frente a N. caninum de 12.2% (12/98). De los 12 sueros positivos, el 75.0% (9) presentaron títulos de 1:100, el 16.7% (2) con 1:200 y el 8.3% (1) con 1:400. No se encontró asociación significativa entre las variables edad, antecedentes de abortos y número de partos con la presentación de serorreactores a N. caninum.

Toxoplasma gondii and Neospora caninum infections in South American camelids in Switzerland and assessment of serological tests for diagnosis

“…However, nothing is known about the efficiency of vertical transmission of N. caninum in SAC or about the meaning of horizontal transmission through the ingestion of sporulated oocysts shed by canids in these animal species. In Peru, no significant association was found between seropositivity to N. caninum in SAC and age [55,56] or geographical region [57], suggesting that the infection might be mainly transmitted vertically [57]. Apart from some regional studies from Peru, in which higher seroprevalences of infection were reported (17.9-42.4 % in alpacas and 18.4-23.3% in llamas) [58,59], only low seroprevalences were observed in studies outside South America, suggesting that only few animals had contact with the parasite.…”
