The zoonotic tapeworm Taenia saginata, although causing only minor discomfort in humans, is responsible for considerable economic losses in the livestock sector due to condemnation or downgrading of infected beef carcasses. An overview of current knowledge on the distribution and prevalence of this parasite in West and Central Africa is lacking.
We conducted a systematic review, collecting information on published and grey literature about T. saginata taeniosis and bovine cysticercosis from 27 countries/territories in West and Central Africa, published between January 1st, 1990 and December 31st, 2017.
The literature search retrieved 1672 records, of which 51 and 45 were retained for a qualitative and quantitative synthesis, respectively. Non-specified human taeniosis cases were described for Nigeria, Cameroon, Senegal, Burkina Faso, Democratic Republic Congo, Guinea, and Ivory Coast (seven out of 27 countries/territories), while T. saginata taeniosis specifically was only reported for Cameroon. Most prevalence estimates for taeniosis ranged between 0-11%, while three studies from Nigeria reported prevalence estimates ranging between 23-50%. None of the studies included molecular confirmation of the causative species. The presence of bovine cysticercosis was reported for Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Democratic Republic Congo, Ghana, Guinea, Ivory Coast, Mali, Niger, Nigeria, Senegal, and Tristan da Cunha (14 out of 27 countries/territories). Prevalence estimates ranged between 0-29%.
Our systematic review has revealed that human taeniosis and bovine cysticercosis are seriously understudied in West and Central Africa. The high prevalence estimates of both conditions suggest an active dissemination of this parasite in the region, calling for a concerted One Health action from public health, veterinary health and food surveillance sectors.
尽管食源性带绦虫(Taenia saginata)在人体内只会引起轻微不适,但由于受感染牛肉胴体被废弃或降级,它在畜牧业中造成了相当大的经济损失。目前缺乏关于该寄生虫在西非和中非的分布和流行情况的概述。
我们进行了系统综述,收集了 1990 年 1 月 1 日至 2017 年 12 月 31 日期间,来自西非和中非 27 个国家/地区的关于带绦虫病和牛囊尾蚴病的已发表和灰色文献信息。
文献检索共检索到 1672 条记录,其中 51 条和 45 条分别被保留进行定性和定量综合分析。在 27 个国家/地区中,有 7 个国家/地区(尼日利亚、喀麦隆、塞内加尔、布基纳法索、刚果民主共和国、几内亚和科特迪瓦)描述了非特异性人类带绦虫病病例,而只有喀麦隆报告了带绦虫病。大多数带绦虫病的流行率估计值在 0-11%之间,而来自尼日利亚的三项研究报告的流行率估计值在 23-50%之间。这些研究均未进行导致该病的物种的分子确认。牛囊尾蚴病的存在被报告在贝宁、布基纳法索、喀麦隆、中非共和国、乍得、刚果民主共和国、加纳、几内亚、科特迪瓦、马里、尼日尔、尼日利亚、塞内加尔和特里斯坦达库尼亚(27 个国家/地区中的 14 个)。流行率估计值在 0-29%之间。
我们的系统综述表明,在西非和中非,带绦虫病和牛囊尾蚴病的研究严重不足。这两种疾病的高流行率估计表明该寄生虫在该地区的传播活跃,呼吁公共卫生、兽医卫生和食品监测部门采取协调一致的“同一健康”行动。
