RESUMO

El objetivo del presente estudio fue determinar la prevalencia de Fasciola hepática en bovinos y ovinos del distrito de Vilcashuamán, Ayacucho, mediante un examen coproparasitológico. Se tomaron 381 y 207 muestras fecales de bovinos y ovinos, respectivamente, durante la época seca (julio y agosto de 2004) y se analizaron mediante la técnica de sedimentación espontánea. Se encontraron prevalencias de 35.9 ± 4.8% y 39.1 ± 6.7%, y una prevalencia corregida de 47.6 ± 5.0% y 52.1 ± 6.8%, para bovinos y ovinos, respectivamente. Las variables especie, sexo y edad no constituyeron factores de riesgo para distomatosis; sin embargo, la tasa de infección se incrementó a medida que aumentó la altitud sobre el nivel del mar (p<0.01), constituyendo la zona de procedencia un factor de riesgo para la enfermedad.


The aim of this study was to determine the prevalence of Fasciola hepaticain cattle and sheep in the district of Vilcashuaman, Ayacucho, using a coproparasitological test. For this study, 381 and 207 fecal samples were taken from cattle and sheep, respectively, during the dry season (July and August 2004) and were analyzed by the spontaneous sedimentation technique. The prevalence was 35.9 ± 4.8% and 39.1 ± 6.7%, and the corrected prevalence was 47.6 ± 5.0% and 52.1 ± 6.8% for cattle and sheep respectively. The species, sex, and age variables were not risk factors for distomatosis; however, the rate of infection showed a direct relationship with the altitude above the sea level (p<0.01), constituting a risk factor for the disease.
