湖南省湘西州部分规模场牦牛流产衣原体流行情况及风险因素调查

摘要

The sero-prevalence ofChlamydophilaabortus infection in yaks was investigated in some scaled breeding farms of Hunan province from January 2015 to January 2016. A total of 812 animal serum samples were collected from Xiangxi autonomous prefecture of Hunan province. All the serum samples were evaluated by indirect hemagglutination test(IHA). The overall sero-prevalence ofC.abortuswas estimated at 17.2%. The risk factors associated with sero-prevalence were determined by multivariate logistic regression analysis. Season and gender of yaks were considered as main risk factors associated withC.abortus infection(P<0.05). The results revealed a widespread and high prevalence ofC.abortus infection in yaks in Hunan province. The suggestions of taking control measures of zoonoticC.abortus infection were put forward,in order to ensure the safety of human and animal health.%本研究旨在查明湖南省湘西州牦牛流产衣原体感染情况并探讨其可能的风险因素。应用间接血凝试验（IHA）方法检测了该地区的825份牦牛血清，并应用流行病学、统计学方法对牦牛衣原体风险因素进行了评估分析。结果显示，牦牛流产衣原体抗体阳性率为17.2%，季节和性别是牦牛流产衣原体感染的主要风险因素（P<0.05）。本研究表明湖南省湘西州牦牛流产衣原体感染率较高，应当对本地区的流产衣原体病采取适当的控制措施，以确保人类和动物的健康安全。
