背景:人畜共患tel带虫,虽然只引起人类轻微的不适,由于谴责或降级受感染的牛肉尸体,对畜牧业造成相当大的经济损失。缺乏关于这种寄生虫在西非和中非分布和流行的最新知识的概述。
方法:我们进行了系统评价,收集来自西非和中非27个国家/地区的有关沙吉纳氏梭菌和牛囊虫病的已出版文献和灰色文献的信息,1月1日之间出版,1990年12月31日,2017.
结果:文献检索检索到1672条记录,其中51和45被保留用于定性和定量合成,分别。尼日利亚描述了非特定的人类头虫病病例,喀麦隆,塞内加尔,布基纳法索,刚果民主共和国,几内亚,和象牙海岸(27个国家/地区中的7个),而Saginatataeniosis仅在喀麦隆报告。大多数对牛病的患病率估计在0-11%之间,而来自尼日利亚的三项研究报告的患病率估计值在23-50%之间。没有一项研究包括对致病物种的分子确认。据报道,贝宁存在牛囊虫病,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,象牙海岸,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)。患病率估计值在0-29%之间。
结论:我们的系统评价显示,在西非和中非,对人类头孢和牛囊虫病的研究严重不足。这两种情况的高流行率估计表明该寄生虫在该地区活跃传播,呼吁公共卫生采取协调一致的“一个健康”行动,兽医卫生和食品监督部门。
BACKGROUND: 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.
METHODS: 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.
RESULTS: 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%.
CONCLUSIONS: 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.
