非人灵长类动物隐孢子虫分子流行病学研究进展

Research progress in molecular epidemiology of Cryptosporidium in non-human primates

隐孢子虫是一种新现的单细胞人兽共患病原体。通过侵犯人和动物的小肠上皮细胞,导致宿主产生以腹泻为主的多种临床症状,可通过水源性、食物源性以及宿主间相互传播,具有重要的公共卫生学意义。研究显示,非人灵长类动物可感染多种隐孢子虫基因型,且该物种与人类基因相似度高,故需引起高度重视。本文就隐孢子虫在非人灵长类动物中的感染率、基因型、人兽共患风险进行综述。

Cryptosporidium is an emerging single-cell zoonotic pathogen.By invading human and animal small intestinal epithelial cells,the host produces a variety of clinical symptoms,mainly diarrhea.Spores of Cryptosporidium can be transmitted through water-borne,food-borne,and mutual transmission between hosts,which has important public health significance.Studies have shown that non-human primates can be infected with multiple Cryptosporidium genotypes.Moreover,this species has a high genetic similarity with humans,so it needs to be taken seriously.This article reviews the infection rates,genotypes,and zoonotic risk of Cryptosporidium in non-human primates.
