The canine lungworm Angiostrongylus vasorum is considered neglected in South America and was only sporadically reported in dogs and wildlife. Gastropods act as obligatory intermediate hosts for this parasitosis. We here analysed Achatina fulica (African giant snail) populations from 5 regions of Colombia for A. vasorum infections. In total, 609 snails were collected from the departments Antioquia, Valle del Cauca and Putumayo. Angiostrongylus vasorum-infected A. fulica were found in all departments with a total prevalence of 3.9%. Larvae originating from Putumayo were molecularly characterized and identified as the European lineage of A. vasorum. This regional report shows for the first time the presence of A. vasorum in intermediate hosts in Colombia and the European genotype in South America.
犬肺线虫血管圆线虫在南美洲被认为是被忽视的，仅在犬类和野生动物中偶尔有报道。腹足纲动物是这种寄生虫病的必需中间宿主。我们在此分析了来自哥伦比亚5个地区的非洲大蜗牛（褐云玛瑙螺）种群是否感染血管圆线虫。总共从安蒂奥基亚省、考卡山谷省和普图马约省收集了609只蜗牛。在所有省份均发现了感染血管圆线虫的非洲大蜗牛，总患病率为3.9%。对来自普图马约省的幼虫进行了分子特征分析，并鉴定为血管圆线虫的欧洲谱系。这份区域报告首次表明哥伦比亚中间宿主中存在血管圆线虫以及南美洲存在欧洲基因型。
