中国奶牛源微小隐孢子虫分子流行病学及其亚型分布

Molecular epidemiology and subtype distribution of Cryptosporidium parvum from dairy cattle in China

在全球范围内,大多数微小隐孢子虫亚型为人兽共感染虫株。奶牛是微小隐孢子虫自然感染的重要宿主,也是人隐孢子虫病的重要传染来源。本文阐述了奶牛源微小隐孢子虫分子流行病学研究进展,分析中国奶牛源微小隐孢子虫Ⅱd亚型的分布特征和多样性分布规律,探讨Ⅱd亚型变异发展趋势,这对微小隐孢子虫病的防控具有重要意义。

Globally,most strains of Cryptosporidium parvum subtypes cause zoonotic infections.Dairy cattle are the important host for the natural infection of C.parvum and the important source of infection for human cryptosporidiosis.In this paper,the molecular epidemiology of C.parvum from dairy cattle was reviewed.The Ⅱ d subtype distribution of C.parvum in dairy cattle in China was analyzed.The diversity distribution of Ⅱ d subtype was summarized and the development trend of Ⅱ d subtype was predicted.This review is of great significance for the prevention and control of C.parvum.
