青海省互助县牛衣原体病的血清学调查

Serological Survey of Bovine Chlamydia in Huzhu County of Qinghai Province

牛衣原体病是由流产嗜性衣原体所引起牛的一种地方性传染病,主要症状包括发热、怀孕母牛繁殖障碍、肺炎、肠炎、多发性关节炎和脑脊髓炎等。流产嗜性衣原体可感染羊和与之密切接触的人,是一种重要的人畜共患病病原。本研究对青海省互助县12个采集点共765份送检血清采用间接血凝试验(IHA)检测衣原体抗体。结果发现,阳性检出率为26.1%(200/765);其中牦牛血清阳性检出率为32.3%(20/62);乳牛血清阳性检出率为25.6%(180/703)。调查结果显示,该地区养殖场的乳牛和牦牛均存在有不同程度的衣原体感染。这些数据为该地区牛衣原体病防制提供了参考依据。

Bovine chlamydiosis caused by Chlamydia abortus is a local infectious disease.The main symptoms include fever,reproductive failure,pneumonia,enteritis,polyarthritis,encephalomyelitis and so on.Chlamydia abortus is an important zoonotic pathogen which infect sheep and human.765serum samples from12collected areas in Huzhu County of Qinghai province were used for antibody detection of Chlamydia infection by indirect hemagglutination test(IHA).The results showed that the total positive rate was26.1%(200/765),while yak serum positive rate was32.3%(20/62),and cow serum positive rate was25.6%(180/703).The results of the survey in the areas of dairy cattle and yak farms have different degree of Chlamydia infection,thus providing reference data for the prevention and control of the bovine chlamydiosis.
