Abstract

Objective: To assess sero-prevalence of porcine cysticercosis in Atahualpa, a rural Ecuadorian village endemic for human neurocysticercosis. Design: We aim to collect at least 600 blood samples of local pigs, to quantify the number of positive bands in the EITB, and to estimate crude prevalence rates of porcine cysticercosis in the village. Sampling will only include pigs older than 2 months of age. Only healthy pigs will be sampled, to avoid risks inherent to manipulation of sick animals. There will be no risk for pigs as the result of the procedure. According to the estimated endemicity of human cysticercosis, we expect to find about 25% of infected pigs in this study. In the event of prevalence rates above or below the expected percentage, we will attempt to assess the causes of such discrepancies. All pig positive to 3 bands of more in the EITB will receive treatment with oxfendazole at a single dose of 30 mg/kg. Comment: The importance of defining the prevalence of porcine cysticercosis in a village endemic for human neurocysticercosis is to confirm the existence of active transmission. If this is true, treatment of infected pigs will help to interrupt the life cycle of Taenia solium, thus reducing the prevalence of this disease in humans..
