青海省祁连县牦牛和山羊的莱姆病螺旋体和Q热柯克斯体血清抗体调查

Sero-prevalence of Borrelia burgdorferi and Coxiella burnetii in Yaks and Goats in Qilian county From Qinghai Province

为了解我国青海省祁连县家畜中莱姆病螺旋体及Q热柯克斯体的自然感染及复合感染状况,收集该地牦牛和山羊的血样标本,采用间接免疫荧光法分别检测血清莱姆病螺旋体及Q热柯克斯体抗体.共收集了200份血样,山羊及牦牛各100份,两种家畜均为当地的主要家畜.结果显示,牦牛血清中有11份为莱姆病螺旋体抗体阳性,23份为Q热柯克斯体抗体阳性 山羊血清中有17份为莱姆病螺旋体抗体阳性,27份为Q热柯克斯体抗体阳性 3只山羊和7头牦牛血清为双抗体阳性.结果提示该地区为莱姆病和Q热的自然疫源地,牦牛和山羊可能隐性感染了Q热柯克斯体和（或）莱姆病螺旋体.

The prevalence of infections and coinfections of Borrelia burgdo（feri s. l. and Coxiella burnetii among domestic animals from Qinhai Province were assessed to give limestone for the disease prevention and control. Sera samples were collected from domestic animals and indirect immunofluorescent asssy （IFA） was carried out to test antibodies （IgG） against Lyme disease spirochete and C. burnetii. A total of 200 sera were tested including 100 goats and 100 yaks which were dominant domestic animals in local region and close related to residents. There were 11 and 23 sera from yak were found positive to Lyme disease spirochete and C. burnetii, respectively. 17 sera from goats were shown positive to Lyme disease spirochete. 27 sera from goats were positive to C. burnetii. Ten animals, involled 3 goats and 7 yaks, were found to be simultaneously infected by the 2 pathogens. These findings demonstrate that these two agents co-circulate in the study region.
