摘要: 本文报告1981年2月至1982年9月在广州地区对广州血管圆线虫的终末宿主——褐家鼠,中间宿主——螺蛳、蛞蝓以及运转宿主——蟾蜍、淡水虾的调查结果。褐家鼠感染率占1.6%,以越秀区感染最高(2.3%),荔湾区次之(1.2%),海珠区最低。褐云玛瑙螺带有广州血管圆线虫第3期幼虫的感染率达29.7%。足襞蛞蝓不仅感染率较高(49.2%)且感染度较重。黑眶蟾蜍170只,仅发现两只阳性。

Abstract: A survey of Angiostrongylus cantonensis in snails, slugs, prawns, toads and rats was carried out in Guangzhou, from Feb 1981 to June 1982. The results were as follows: (1) 164 out of 10,034 Rattus norvegicus (1.6%) were naturally parasitized with Angiostrongylus cantonensis. A comparison between the parasitic fauna of three different districts in Guangzhou showed that the infected rate was higher in Yuexiu (2.3%) than in Liwan (1.2%) and Haizhu (0.3%). (2) 98 out of 330 giant African snails, Achatina Julica (29.7%) were parasitized with the third stage larvae of Angio-strongylus cantonensis. (3) In 63 Vaginufus sp. and 494 Philomycus bilineatus were recovered respectively 56,060 and 1,577 third stage larvae. (4) The role of Bufo me-lanostictus and a species of freshwater prawns, Macrobrachium nipponense as paratenio hosts for Angiostrongylus cantonensis third stage larvae could not be demonstrated
