Cysticercosis is a parasitic disease due to the infection of man with Cysticercus cellulose, the larva of Taenia solium. This disease is frequent in countries with low socio-economic development and is linked to sanitary conditions. The aim is to assess the seroprevalence of cysticercosis in the lacustrine vicinity of Vekky, located on the lake Nokoué, District Atlantic, south Benin, an epidemiological survey was undertaken in April and May 1994. The lacustrian vicinity of Vekky comprises 12 villages including 16, 142 inhabitants. Population has been sampled using cluster sampling method (n = 30) at two levels (village and household). The whole samples consisted in 319 adults (123 females and 196 males, mean of ages: 32.8 +/- 18.3). Titration of cysticercosis antibodies has been made using ELISA. Eleven patients (3 females and 8 males) showed a positive ELISA response for cysticercosis, i.e. the seroprevalence of cysticercosis was 3.5% (CI 95%:1.3-8%). There was no significant difference according to age and sex. The seroprevalence of cysticercosis reached 9.1% in patients who presented history of epilepsy. We failed to find any linkage between seropositivity and i) clinical history of epilepsy or taeniasis, or ii) several studied environmental factors such as consumption of pork, wandering of pigs, lack of veterinary supervision, religion and occupation. Human seroprevalence of cysticercosis reaches 3.5% in vicinity of Vekky, which denotes a high endemic level. Further epidemiological studies are necessary to precise the factors involving cysticercosis in this area.
囊尾蚴病是一种寄生虫病,由猪带绦虫的幼虫猪囊尾蚴感染人体所致。这种疾病在社会经济发展水平较低的国家较为常见,且与卫生条件相关。目的是评估位于贝宁南部大西洋区诺库埃湖的韦基湖周边地区囊尾蚴病的血清流行率,于1994年4月和5月进行了一项流行病学调查。韦基湖周边地区包括12个村庄,有16,142名居民。采用整群抽样方法在两个层面(村庄和家庭)进行抽样(n = 30)。整个样本包括319名成年人(123名女性和196名男性,平均年龄:32.8 +/- 18.3岁)。使用酶联免疫吸附测定法(ELISA)检测囊尾蚴病抗体。11名患者(3名女性和8名男性)ELISA检测显示囊尾蚴病抗体呈阳性反应,即囊尾蚴病的血清流行率为3.5%(95%置信区间:1.3 - 8%)。按年龄和性别无显著差异。有癫痫病史的患者中囊尾蚴病血清流行率达9.1%。我们未发现血清阳性与以下因素之间存在任何关联:i)癫痫或绦虫病的临床病史,或ii)一些研究的环境因素,如猪肉消费、猪的放养、缺乏兽医监管、宗教和职业。韦基周边地区囊尾蚴病的人类血清流行率达3.5%,表明地方流行程度较高。需要进一步开展流行病学研究以明确该地区囊尾蚴病的相关因素。
