大理地区鼠类动物肝毛细线虫感染情况调查

目的　调查大理地区鼠类动物肝毛细线虫感染的情况。　方法　在室内和室外采用捕鼠笼、鼠夹和电子捕鼠器捕捉鼠类动物 ,并确定其种类 ,解剖检查和镜检肝毛细线虫感染情况。　结果　共捕获鼠类动物 113 2只 ,分属 3目 6科 13属 2 3种 ,齐氏姬鼠为野外常见种 ,褐家鼠为室内优势种。感染肝毛细线虫的鼠共 2 3 8只 ,分属 2目 8种 ,感染率为2 1.0 2 %。家栖鼠类感染普遍 ,感染率为 76.83 % ,以褐家鼠和黄胸鼠感染率较高 ,分别是 77.0 1%和 77.46%。野栖鼠类感染率低 ,为 4.47% ,但斯氏家鼠感染率可达 3 8.81%。　结论　大理地区鼠类肝毛细线虫感染相当普遍 ,家栖鼠类感染率较高 ,预防人群肝毛细线虫的感染是十分必要的。

INVESTIGATION ON RATS INFECTED WITH CAPILLARIA HEPATICA IN DALI

Objective To investigate the infection rate of Capillaria hepatica in rats in Dali. Methods Rats were captured by mouse-trap, and the species of rat were identified. Then infection of C. hepatica was tested. Results Altogether 1 132 rats were captured. They were identified as 23 species, belong to 13 genera, 6 families, 3 orders. The dominant species outside was A. cheverier i, and the dominant species inside was R. norvegicus . 238 rats were infected with C. hepatica , they were identified as 8 species, 2 orders, the infection rate of C. hepatica was 21.02%. Rats in house, the infection rate was 76.83%, and that of R. norvegicus and R. flavipectus were higher than others with 77.01% and 77.46% respectively. Rats in wild, the infection rate was 4.47%, while the infection rate of in R. rattus sladeni was 38.81%. Conclusion Rats infected with C. hepatica was common in Dali, especially house rats. It's necessary to prevent the infection of C. hepatica in population.
