我国猪群隐孢子虫感染情况及人兽共患风险分析

摘要/Abstract

摘要： 隐孢子虫（Cryptosporidium）是一种重要的人兽共患寄生原虫,是引起隐孢子虫病（cryptosporidiosis）的病原。隐孢子虫可以通过水和食物感染包括人和家畜、家禽在内的多种宿主,引起宿主出现腹泻等症状,严重时可导致死亡,这不仅给畜禽养殖业造成巨大的经济损失,而且对公共卫生安全造成严重威胁。目前尚未见针对隐孢子虫病的有效疫苗或特效药物,因此,隐孢子虫病的流行病学调查显得尤为重要。对我国猪群隐孢子虫感染率、感染虫种分布、感染风险因素方面的研究进展进行综述,并对其人兽共患风险进行分析,以期为我国猪隐孢子虫病的综合防控提供参考。

Abstract: Cryptosporidium is an important genus of parasitic protozoa and is the causative agent for cryptosporidiosis. Cryptosporidium is capable of infecting various hosts （human, livestock and poultry） through water and food, causing symptoms such as diarrhea and even death. It not only brings huge economic losses to livestock and poultry farming, but also poses a serious threat to public health and safety. At present, there are no effective vaccines or specific drugs against cryptosporidiosis. Accordingly, the epidemiological investigation of this disease is particularly critical. In this paper, we reviewed the research progress on infection rate, species distribution, infection risk factors of Cryptosporidium in pig herds in China, and assessed the zoonotic risk, in hoping to provide references for the effective prevention and control against pig cryptosporidiosis.

Key words: Cryptosporidium, pig, molecular epidemiology, zoonosis, risk factor
