摘要
目的了解茂名市区和电白县鼠类广州管圆线虫感染情况,为该地区广州管圆线虫防治工作提供参考依据。方法在村内和野外采用鼠夹和捕鼠笼等方法捕捉鼠类,在确定种类后,取其心肺组织检查广州管圆线虫成虫。结果共检查鼠148只,阳性15只,鼠广州管圆线虫的总感染率为10.14%。褐家鼠、黄胸鼠和小家鼠的感染率分别为12.87%、4.76%和0。野栖鼠和家栖鼠感染率分别为17.14%(12/70)和3.85%(3/78)。结论茂名市区和电白县鼠类中存在广州管圆线虫的感染,褐家鼠是最主要的终末宿主。同时,野栖鼠的感染率明显高于家栖鼠。
Objective To know the natural infection rates of Angiostrongylus cantonensis in murine from Maoming city and Dianbai county of Guangdong province and provide some information for control of the parasite. Methods The rats were caught with mousetrap or mouse cage from outdoor in Maoming city and Dianbai county, and were classified to species. The Angiostrongylus cantonensis adult worms were examined in lungs and heart of the rats. Results 148 rats of three different species were collected; total infection rate of Angiostrongylus cantonensis in the rats is about 10.14%. The natural infection rates of Angiostrong＇ylus cantonensis in Rattus norvegicus, Rattus flavipectus and Mus musculus are 12.87%（13/101）, 4.76%（2/42） and 0%（0/5）, respectively. The infection rates of rats captured from the wild and around houses are 17.14% （12/70） and 3.85% （3/78）, respectively. Conclusion There is infection of Angiostrongylus cantonensis in murine from Maoming city and Dianbai county and Rottus norvegicus is most important definitive host of Angiostrongylus cantonensis in the epidemic area. The infection rates of rats captured from the wild is significant higher than those around houses.
