Abstract

© 2003 Universidad Nacional Mayor de San Marcos. All rights reserved. The study assessed the prevalence of porcine cysticercosis in three villages (Isla Noblecilla, Tutumo and Nuevo Progreso) from Matapalo district, in Tumbes, Peru. All pigs excepting pregnant sows and piglets younger than two-months old were censused and ear-tagged, and a blood sample was collected. Antibodies against T. solium were determined in serum samples using the Enzime linked Immuno Electro Transfer Blot Assay (EITB). Some risk factors associated with the presence of antibodies against Cysticercus cellulosae were estimated. The total prevalence was 26% (139/534). Prevalence rates were 85/236 (36%), 45/276 (16%) and 9/22 (41%) for Nuevo Progreso, Tutumo and Isla Noblecilla respectively. Variables associated with presence of antibodies were village (P = 0.005) and age (P < 0.001). Information on the number of reaction bands in the EITB assay was used to predict the actual prevalence of T. solium infection in pigs using the beta-binomial stochastic simulation (@Risk 4.0 software). According to the simulation, 90% of the expected prevalences were contained in the 9-15% interval. It was concluded that T. solium transmission is occurring in both human and porcine populations.
