【摘要】 为了解西北地区牛包虫病的流行情况，此次对青海省和甘肃省部分地区开展牦牛、肉牛及奶牛包虫病流行病学调查。对甘肃省和青海省6个城市11个县区的817份牛血清，利用间接ELISA方法进行包虫病检测，并对不同地区、不同品种和养殖方式的差异进行生物学统计。采集的青海省和甘肃省部分地区牛血清包虫病总阳性率为3.7%(30/817),其中牦牛阳性率为5.5%(25/458),奶牛阳性率为2.0%(5/249),肉牛未检测到阳性样本。青海省牛包虫病血清阳性率(4.5%)略高于甘肃省(3.4%),但差异不显著(P>0.05)。甘肃省不同县区的牛包虫病血清阳性率差异显著(P<0.05),流行率在0%～7.3%之间。对不同饲养方式的牛进行统计分析，显示圈养牛包虫病的血清阳性率为1.4%,显著低于散养牛(5.5%)。青海省和甘肃省为我国两大重要牧区，包虫病在这两省仍持续流行，应继续探索操作性强、易推广的牛包虫病综合防控措施，以降低该病在两省的流行。更多还原

【Abstract】 To investigate the prevalence of Bovine echinococcosis in the northwestern region of China, an epidemiological investigation was carried out in yak, beef cattle and dairy cattle in several areas of Qinghai and Gansu provinces.A total of 817 bovine sera from 11 counties in 6 cities of Gansu and Qinghai provinces were tested for the seroprevalence of echinococcosis using indirect ELISA method.The differences between regions, breeds and farming methods were analyzed by statistical analysis.The overall positive rate of echinococcosis in the bovine serum samples collected from Qinghai and Gansu provinces was 3.7%(30/817),of which in yaks was 5.5%(25/458),2.0%(5/249) in dairy cows, and no positive samples in beef cattle.The seropositive rate of Bovine echinococcosis in Qinghai Province(4.5%) was slightly higher than that in Gansu Province(3.4%),but the difference was not significant(P>0.05).In Gansu Province, the seropositive rates of Bovine echinococcosis in different areas were varied from 0% to 7.3%,which showed significant differences(P<0.05).Statistical analysis revealed that the seroprevalence of echinococcosis in stall-fed cattle(1.4%) is significantly lower than that in free-ranging cattle(5.5%).Qinghai and Gansu provinces are two important pastoral areas in China, but the Bovine echinococcosis is still prevalent in these two provinces.The present study indicates that the operable, generalized prevention and control measures are urged to develop to reduce the prevalence of Bovine echinococcosis in these two provinces.更多还原
