摘　　要：目的调查大理市家栖鼠类动物肝毛细线虫(Capillaria hepatica)的感染情况,为该地区肝毛细线虫病的监测与防治提供参考资料。方法用鼠笼加食饵诱捕获市区家栖鼠类动物,鉴定鼠种、鼠龄、性别等。解剖鼠类,肉眼观察肝脏病变,并进行肝组织压片于显微镜下镜检虫卵。结果捕获鼠类2种(褐家鼠、黄胸鼠)287只,肝毛细线虫总自然感染率为20.21%(58/287),其中褐家鼠感染率为19.26%(52/270)、黄胸鼠感染率为35.29%(6/17);成年鼠感染率为21.05%(40/190)、幼年鼠感染率为18.56%(18/97);雄性宿主感染率27.68%(31/112)高于雌性宿主15.43%(27/175),且差异有统计学意义(χ^2=6.355,P<0.05);性别与肝毛细线虫感染有相关性(P<0.05,OR=0.477);而肝毛细线虫感染率在鼠种、性别及季节上的差异无统计学意义。结论家栖鼠类肝毛细线虫的感染率高,向人类传播疾病的风险增大,加强开展大理市区防鼠灭鼠工作十分必要。Objective To investigate the infection of Capillaria hepatica(C hepatica)in domestic rodents in Dali,and to provide a reference for the surveillance and prevention of this disease.Methods Domestic rodents in urban areas were captured by traps with food in order to identify the species,age and sex.Then the rodents were dissected to observe the liver lesions with the naked eye,and liver tissue slice was put under the microscope to examine the eggs.Results A total of 287 rodents(Rattus norvegicus,Rattus flavipectus)were captured.The total natural infection rate of C hepatica was 20.21%(58/287).The infection rates of R norvegicus,R flavipectus,adult rodents and young rodents were 19.26%(52/270),35.29%(6/17),21.05%(40/190)and 18.56%(18/97),respectively.The infection rate of male hosts 27.68%(31/112)was higher than that of female hosts 15.43%(27/175),and the difference was statistically significant(χ^2=6.355,P<0.05).Gender was associated with C hepatica infection(P<0.05,OR=0.477).There was no statistically significant difference in C hepatica infection rate in host species,sex and season.Conclusion The infection rate of C hepatica in domestic rodents is high,and the risk of human infection is increasing.It is necessary to strengthen rodent control in Dali City.
