The aim of this study was to determine, through the Indirect Immunofluorescence (IFAT) technique, the frequency of antibodies against Neospora caninum in llamas from the Livestock Association of Lachocc, Huancavelica. Blood samples were taken from 98 adult female llamas, older than one year. The sera were analysed by IFAT using a cut-off point of 1:100. The positive sera were titrated with serial dilutions, determining a frequency of antibodies against N. caninum of 12.2% (12/98). Of the 12 positive sera, 75.0% (9) had titres of 1:100, 16.7% (2) with 1:200 and 8.3% (1) with 1:400. No significant association was found between the variables age, history of abortions and parity with the presentation of seroreactors to N. caninum.

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.
