摘要: 目的 调查福州市广州管圆线虫终末宿主的分布与感染状况。方法 在9个县(市、区)以笼捕法将捕获鼠类鉴定后逐一解剖,查找寄生在鼠心、肺血管内的广州管圆线虫。结果 共解剖鼠类1965只,广州管圆线虫平均感染率为13.69%(269/1965),除平潭县未查到感染鼠外,其他县(市、区)捕获的4种鼠类均感染广州管圆线虫,以褐家鼠的感染率最高为22.44%,黄胸鼠次之为11.76%。结论 福州市除平潭县外均为广州管圆线虫自然疫源地,褐家鼠为主要终末宿主。

Abstract: Objective To investigate the distribution and infection situation of the definitive host of Angiostrongylus cantonensisin Fuzhou.Methods Rodents were trapped using cage in nine counties(cities or districts).After identified the rodents were dissected,and then parasitic An.cantonensis was examined in the cardiovascular and pulmonary vessels of the rodents.Results 1965 rodents were dissected,and the average infection rate of An.cantonensis was 13.69%(269/1965).Except Pingtan county in the other counties(cities or districts) four species of rodents were found to be infected by An.cantonensis.The highest infection rate was 22.44% in Rattus norvegicus,followed by R.flavipectus with 11.76% infected.Conclusion Except Pingtan,the whole Fuzhou area is the natural epidemic foci of An.cantonensis and R.norvegicus is the major definitive host.
