摘要/Abstract

摘要： 本研究旨在查明甘肃与宁夏地区奶牛衣原体的感染情况并分析影响其感染的风险因素。本试验采用间接血凝试验(IHA)方法检测了甘肃榆中(751份)、宁夏青铜峡(450份)和宁夏吴忠(456份)3个地方总计1 657份奶牛血清样品,并应用流行病学调查及统计学方法对影响奶牛衣原体感染的因素进行了分析。流行病学调查结果显示,奶牛衣原体抗体总阳性率为29.33%;应用logistic回归分析评估奶牛衣原体感染的风险因素,结果显示年龄和胎次不是显著风险因素(P>0.05),而地区因素是影响奶牛衣原体感染的风险因素(P<0.05)。奶牛衣原体抗体滴度最高达1:1 024。结果表明,甘肃和宁夏地区奶牛衣原体普遍流行。因此,应当提高对调查地区奶牛衣原体感染的重视,采取适当的综合控制方法和有效的管理措施以防控奶牛衣原体病,以保证奶牛养殖业的经济效益。

Abstract: The objective of the present investigation was to examine seroprevalence of Chlamydia in dairy cattle in Gansu and Ningxia areas, Northwest China, and to analyze the factors affecting Chlamydia infection in dairy cattle.Indirect hemagglutination assay (IHA) was used to detect antibodies against Chlamydia in 1 657 dairy cattle serum samples from Gansu and Ningxia areas.Epidemiological investigation and statistical methods were used to analyze the data.The results showed that the overall seroprevalence was 29.33%, logistic regression analysis was applied to evaluate the risk factors of Chlamydia infection in dairy cattle, and the results indicated that age and numbers of pregnancy of dairy cattle were not the significant risk factors (P>0.05), and were left out of the final model, however, region was considered as the main risk factor associated with Chlamydia infection (P<0.05).The highest titer was 1:1 024.In conclusion, the results of the present survey indicated the widespread of Chlamydia infection in Gansu and Ningxia areas.In order to ensure the economic benefit of dairy farming, we should pay more attention to Chlamydia infection in dairy cattle, and integrated control strategies and efficient management measures should be implemented to prevent and control Chlamydia infection in dairy cattle.
