广州管圆线虫是人类神经管圆线虫病（表现为嗜酸性粒细胞性脑膜炎）的最常见病因。腹足类软体动物被用作中间宿主，各种鼠是这种寄生虫的最终宿主。在这项研究中，我们确定了几个环境因素与存在和丰富的陆生腹足类在巴西的贫困城市地区。城市褐家鼠的身体状况、年龄、是否与其他寄生虫共感染以及环境因素与A.广州线虫感染研究区域还发现啮齿动物中线虫的中度流行率（168人中的33%）。共鉴定出8种软体动物577只，其中4种为A.广东话。我们的研究表明，贫困城市地区的环境条件（存在自来水和积水，污水，湿度和雨水积累和建筑材料的积累）影响陆生腹足类的分布和丰度，以及感染的大鼠，有助于维持A。广州管蚜在该地区的传播周期。除了神经管圆线虫病，这些宿主的存在也可能有助于对其他人畜共患病的易感性。
The nematode Angiostrongylus cantonensis is the most common cause of neuroangiostrongyliasis (manifested as eosinophilic meningitis) in humans. Gastropod molluscs are used as intermediate hosts and rats of various species are definitive hosts of this parasite. In this study, we identified several environmental factors associated with the presence and abundance of terrestrial gastropods in an impoverished urban region in Brazil. We also found that body condition, age and presence of co-infection with other parasite species in urban Rattus norvegicus, as well as environmental factors were associated with the probability and intensity of A. cantonensis infection. The study area was also found to have a moderate prevalence of the nematode in rodents (33% of 168 individuals). Eight species of molluscs (577 individuals) were identified, four of which were positive for A. cantonensis. Our study indicates that the environmental conditions of poor urban areas (presence of running and standing water, sewage, humidity and accumulated rain and accumulation of construction materials) influenced both the distribution and abundance of terrestrial gastropods, as well as infected rats, contributing to the maintenance of the A. cantonensis transmission cycle in the area. Besides neuroangiostrongyliasis, the presence of these hosts may also contribute to susceptibility to other zoonoses.
