环孢子虫食源性感染及其检测技术研究进展

环孢子虫（Cyclospora）是一种新发现的细胞内寄生的肠道寄生性原虫，食入被环孢子虫卵囊污染的蔬菜或水果会引起感染发病，环孢子虫主要寄生于人类和啮齿类、爬行类、哺乳类、非人灵长类等动物体内。环孢子虫病在世界范围内散在感染或暴发流行，主要引起人和动物的胃肠炎和腹泻等症状，甚至导致死亡，造成严重的健康威胁和经济损失。本文概述近几年来环孢子虫的分类情况、遗传特性研究、流行病学现状以及常用检测技术等方面的研究进展。

Advances in Research on Food-Borne Infection and Detection Methods of Cyclospora

Cyclospora is a newly discovered protozoan parasite that can infect intestinal epithelial cells. The pathogen canbe transmitted by consumption of vegetables or fruits contaminated with oocysts. It mainly parasitizes humans and rodents,reptiles, mammals including non-human primates, and other animals. Cyclosporiasis as a sporadic infection or outbreakcan cause human and animal gastroenteritis and diarrhea, and even lead to death along with serious economic loss. Thisarticle summarizes Cyclospora classification, genetic characteristics, epidemiological status and commonly used detectiontechniques in recent years.
