The aim of this study was to determine the prevalence of antibodies against Chlamydophila abortus in cattle from the districts of Coracora, Chumpi and Pullo of the province of Parinacochas, department of Ayacucho, Peru. The animals were raised extensively and under natural breeding. In total, 184 blood samples were taken from cattle over 4 months of age regardless of sex. The detection of antibodies against C. abortus was done with a commercial indirect ELISA kit. A corrected prevalence of 40.34 ± 7.06% was obtained with a significant difference between districts (p<0.05), being lower in Coracora (40.29 ± 8.89%) and higher in Pullo (56.05 ± 7.15%), and without significant differences due to the effect of sex. breed, animal category and reproductive status. The high prevalence confirms the spread of the pathogen in the bovine population of the evaluated districts.  

El objetivo del presente estudio fue determinar la prevalencia de anticuerpos contra Chlamydophila abortus en el ganado bovino de los distritos de Coracora, Chumpi y Pullo de la provincia de Parinacochas, departamento de Ayacucho durante el 2018 donde los bovinos son criados de forma extensiva y con reproducción por monta natural. Se obtuvo aleatoriamente 460 muestras de suero sanguíneo en bovinos mayores de 4 meses de edad sin considerar sexo. Para la detección de anticuerpos contra Chlamydophilia abortus se usó el ensayo por inmunoabsorción ligado a enzimas (ELISA) indirecto de uso comercial. Se obtuvo una prevalencia corregida de 40.34% + 7.06% (74/184) en bovinos que presentaron anticuerpos contra Chlamydophilia abortus; donde la menor prevalencia corregida fue en el distrito de Coracora con 40.29% + 8.89% (47/117) y la mayor prevalencia corregida en el distrito de Pullo con 56....
