宁夏回族自治区奶牛感染贝氏柯克斯体的血清流行病学调查
|
摘要
目的调查宁夏回族自治区奶牛感染贝氏柯克斯体状况。方法通过酶联免疫吸附试验(ELISA)检出奶牛血清贝氏柯克斯体抗体,总体阳性率为11.37%(103/906)。结果吴忠市和青铜峡市奶牛贝氏柯克斯体抗体阳性率分别为12.28%和10.44%;不同年龄组的抗体阳性率为9.86%至13.21%;未生育过的奶牛抗体阳性率最高为11.99%。结果显示地区、年龄和胎次均与贝氏柯克斯体感染无统计学差异(P>0.05)。结论揭示了宁夏地奶牛贝氏柯克斯体感染普遍存在,对该地区人群健康构成潜在威胁。
The aim of this present study was to examine the seroprevalence of Coxiella burnetii infection in randomly selected dairy cattle in Ningxia Hui Autonomous Region(NXHAR),Northwest China.The overall C.burnetii seroprevalence was 11.37%(103/906)by ELISA.The seroprevalence of C.burnetii was 12.28% and 10.44% in dairy cattle,in Wuzhong and Qingtongxia respectively.The seropositive rate ranged from 9.86% to 13.21%in different age groups.Dairy cattle with no pregnancy had the highest seroprevalence(11.99%).Geographical location,age and number of pregnancies had no apparent association with C.burnetii seropositivity(P>0.05).This survey indicates that C.burnetii infection is highly prevalent in dairy cattle in NXHAR,which may pose a potential threat to human health.
