In January and February 2019, a malacological survey was conducted in the area surrounding the residence of a 12-year-old child that had contracted cerebral angiostrongyliasis in the municipality of Macapá, capital of the Amapá State, northern Brazil. The serological examination was positive for Angiostrongylus cantonensis infection, the principal etiological agent of this parasitosis. A sample of 54 molluscs was artificially and individually digested for parasitological analysis, containing 38 specimens of Achatina fulica, nine specimens of Bulimulus tenuissimus and seven specimens of Sarasinula linguaeformis. A. fulica was the most abundant mollusc, and the only species infected with A. cantonensis, as well as presenting co-infections with other nematodes. This is the first report of cerebral angiostrongyliasis in the Amazon Region, and the first record of A. fulica infected with A. cantonensis in Amapá. These findings highlight the potential risks of human angiostrongyliasis, and the need to implement public health measures to control the spread of the disease.

巴西亚马逊地区马卡帕市的广州人圆线虫对人类和蜗牛褐锈病的感染。

2019年1月和2019年2月，在巴西北部阿马帕州首府马卡帕市一名12岁儿童患有脑血管性毛细血管病的住所周围地区进行了一次乳汁病调查。血清学检查表明该寄生虫病的主要病原体是广州血管圆线虫感染。人工地和单独地消化了54个软体动物的样本，以进行寄生虫学分析，其中包含38个褐孔霉菌标本，9个鳞翅目虫标本和7个舌尖灵芝标本。顶叶农杆菌是最丰富的软体动物，也是唯一被广州土壤杆菌感染的物种，并且与其他线虫同时感染。这是亚马逊地区脑血管新生病的首次报道，以及在Amapá感染A. cantonensis的A. fulica的首次记录。这些发现凸显了人类血管平滑肌病的潜在风险，以及实施公共卫生措施以控制疾病传播的必要性。
