青海省湟源县牛、羊衣原体血清流行病学调查

Serological Epidemiology of Cattle and Sheep Chlamydia in Huangyuan County

衣原体病是一种由鹦鹉热衣原体感染引发的传染病,该致病原能引起不同种类动物出现多症候群疾病,牛、羊感染衣原体后主要表现为流产、早产、死胎以及肺炎、多发性关节炎,种公羊和种公牛感染衣原体后,表现为睾丸炎,附睾炎,睾丸坏死,使养殖场种公畜失去配种能力。为进一步掌握青海省湟源县牛、羊衣原体病流行现状,于2019—2020年分别对湟源县城关镇、东峡乡、和平乡、巴燕乡4个牛、羊养殖主要乡镇开展衣原体血清流行病学调查,结果显示,2019年牛、羊衣原体血清阳性率分别为7.19%和8.92%,2020年牛、羊衣原体血清阳性率分别为4.56%和7.30%,阳性率有下降趋势,但仍是威胁当地牛、羊养殖产业健康发展的主要传染性疾病,需要做好防控。

Chlamydia is a zoonotic disease caused by Chlamydia psittaci infection,the causative agent can cause multi-syndromic diseases in different species of animals,cattle and sheep infected with Chlamydia mainly manifested as abortion,premature birth,stillbirth and pneumonia,multiple arthritis,rams and bulls infected with Chlamydia,manifested as orchitis,epididymitis,testicular necrosis,so that the farm breeding males lose the ability to breed.In order to further grasp the specific occurrence and epidemic status of cattle and sheep chlamydia in Huangyuan County,Qinghai Province,from 2019 to 2020,four major cattle and sheep breeding townships in Huangyuan County,Chengguan Town,Dongxia Township,Heping Township,and Bayan Township will be investigated.Carry out a chlamydia seroepidemiological survey.Through this survey,it can be concluded that the seroprevalence rates of bovine chlamydia in 2019 are 8.92%and 7.19%,respectively,and the seroprevalence rates of chlamydia bovine in 2020 are 7.30%and 4.56%,respectively,and the positive rate level It is showing a gradual decline,but it is still a major infectious disease threatening the healthy development of the cattle and sheep breeding industry,and we need to take targeted prevention and control.
