Taenia solium is a cestode parasite that causes cysticercosis in both humans and pigs. A serological survey was undertaken to assess the seroprevalence and risk factors associated with porcine cysticercosis in the rural district of Morropon, Peru. Pigs aged between 2 and 60 months were assessed by the Enzyme-linked Immunoelectrotransfer blot (EITB) assay to determine their serological status against porcine cysticercosis in a cross-sectional study. A total of 1,153 pigs were sampled. Porcine seroprevalence was 45.19% (42.31-48.06). The information about the animals and households was analyzed and risk factors associated with seroprevalence were determined by a multivariate logistic regression analysis. In the porcine population, the risk of being seropositive increased by 7% with every month of age (OR 1.07, 95% CI 1.05-1.09), and by 148% for pigs living in East Morropon (OR 2.48, 95% CI 1.82-3.37). Whereas, the presence of latrines in a household decreased the risk of being seropositive by 49% (OR 0.51; 95% CI 0.39-0.67). Sex and rearing system did not represent either risk or protective factors associated with the seroprevalence of porcine cysticercosis. The findings of this study could be used for further development of control programs that might focus on similar population groups within rural communities of developing countries where cysticercosis is endemic.
猪带绦虫是一种绦虫寄生虫，可在人类和猪中引起囊尾蚴病。进行了血清学调查，以评估秘鲁莫罗蓬农村地区猪囊尾蚴病的血清流行率和相关风险因素。在横断面研究中，通过酶联免疫电泳转移印迹（EITB）检测评估了 2 至 60 月龄的猪，以确定其针对猪囊尾蚴病的血清学状态。共采集了 1153 头猪。猪的血清流行率为 45.19%（42.31-48.06）。分析了有关动物和家庭的信息，并通过多变量逻辑回归分析确定了与血清流行率相关的风险因素。在猪群中，每增加一个月的年龄，感染的风险就会增加 7%（OR 1.07，95%CI 1.05-1.09），而住在东莫罗蓬的猪的感染风险增加 148%（OR 2.48，95%CI 1.82-3.37）。然而，家庭中存在厕所可使感染的风险降低 49%（OR 0.51；95%CI 0.39-0.67）。性别和饲养系统既不是猪囊尾蚴病血清流行率的风险因素，也不是保护因素。本研究的结果可用于进一步制定控制计划，这些计划可能侧重于发展中国家农村社区中囊尾蚴病流行的类似人群。
