摘要
为掌握张掖市2017-2021年包虫病流行和防控情况,对张掖市牛羊脏器棘球蚴包囊、羊棘球蚴感染抗体、犬棘球蚴粪抗原、羊棘球蚴免疫抗体及犬驱虫和宣传培训情况进行了统计分析.结果显示:牛羊脏器棘球蚴包囊平均检出率为 2.24%(898/40 002),其中牛阳性率为 1.63%(77/4 727),羊阳性率为 2.33%(821/35 275);羊棘球蚴感染抗体平均阳性率为 3.39%(172/5 079);犬棘球蚴粪抗原平均阳性率为 0.24%(7/2 872);羊棘球蚴免疫抗体平均阳性率为90.42%(2 767/3 060);饲养犬平均登记率为76.33%(356 700/467 300),登记犬平均驱虫率为 94.15%(335 823/356 700);累计举办各类培训班504场,培训基层防疫人员和农牧民10.87万人,累计发放宣传资料 33.39 万份.结果表明:张掖市包虫病防控工作成效显著,但仍然存在一定的牛羊棘球蚴感染.建议采取"驱虫+免疫"双源头控制措施进行综合防控,同时定期监测犬粪抗原和羊血清抗体来评价综合防控效果.
Abstract
In order to investigate the prevalence and control effects of echinococcosis in Zhangye City from 2017 to 2021,Echinococcus cysts in cattle and sheep organs,antibodies against Echinococcus in sheep,antigens of Echinococcus in canine feces,immune antibodies in sheep and dog desinsectization as well as publicity and training were statistically analyzed.The results showed that the average detection rate of Echinococcus cysts in cattle and sheep organs was 2.24%(898/40 002),specifically,the positive rate in cattle was 1.63%(77/4 727),and that in sheep was 2.33%(821/35 275);the average positive rate of antibodies against Echinococcus in sheep was 3.39%(172/5 079),that of antigens in canine feces was 0.24%(7/2 872),and that of immune antibodies in sheep was 90.42%(2 767/3 060);the average registration rate of captive dogs was 76.33%(356 700/467 300),and the average desinsectization rate of registered dogs was 94.15%(335 823/356 700);a total of 504 training classes with different topics had been organized,involving 108 700 local animal health workers,farmers and herdsmen,and 333 900 pieces of promotional materials were handed out.In conclusion,good achievements were received by the efforts of echinococcosis control in Zhangye,although Echinococcus infection was found in cattle and sheep to certain extent.It was thus recommended to comprehensively prevent the disease through"desinsectization + immunization",the dual source control measures,and to regularly monitor dog fecal antigens and sheep serum antibodies to evaluate the effect of the measures.
