A survey was conducted in 150 households owning 1756 pigs in the rural areas of Mayo-Danay division in the north of Cameroon. A questionnaire survey was carried out to collect information on the pig-farming system and to identify potential risk factors for Taenia solium cysticercosis infection in pigs. Blood samples were collected from 398 pigs with the aim of estimating the seroprevalence of T. solium cysticercosis. The results showed that 90.7% of the pigs are free roaming during the dry season and that 42.7% of households keeping pigs in the rural areas have no latrine facility. Seventy-six per cent of the interviewed pig owners confirmed that members of the household used open-field defecation. Enzyme-linked immunosorbent assay (ELISA) for antigen and antibody detection showed an apparent prevalence of cysticercosis of 24.6% and 32.2%, respectively. A Bayesian approach, using the conditional dependence between the two diagnostic tests, indicated that the true seroprevalence of cysticercosis in Mayo-Danay was 26.6%. Binary logistic regression analysis indicated that a lack of knowledge of the taeniasis-cysticercosis complex and the absence of a pig pen in the household were associated with pig cysticercosis.
在喀麦隆北部马约 - 达奈分区的农村地区，对150户拥有1756头猪的家庭进行了一项调查。开展了问卷调查，以收集有关养猪系统的信息，并确定猪感染猪带绦虫囊尾蚴病的潜在风险因素。从398头猪采集了血样，目的是估计猪带绦虫囊尾蚴病的血清阳性率。结果显示，90.7%的猪在旱季自由放养，农村地区42.7%的养猪家庭没有厕所设施。76%的受访养猪户确认家庭成员在露天排便。用于抗原和抗体检测的酶联免疫吸附测定（ELISA）显示，囊尾蚴病的表观患病率分别为24.6%和32.2%。采用贝叶斯方法，利用两种诊断测试之间的条件依赖性，表明马约 - 达奈囊尾蚴病的真实血清阳性率为26.6%。二元逻辑回归分析表明，对绦虫病 - 囊尾蚴病复合体缺乏了解以及家庭中没有猪圈与猪囊尾蚴病有关。
