On the course of a helminthological survey of the dogs of Baranya County, Hungary Angiostrongylus vasorum infection was detected in two asymptomatic dogs. Identification of the parasite was based on morphology of the first-stage larvae (L1) isolated from droppings, and successful experimental infection with first stage larvae to laboratory reared Discus rotundatus and Lissachatina fulica snails, in order to exclude species of the family Filaroididae that have similar larvae to A. vasorum. While angiostrongylosis is widespread among foxes, this is the first report of A. vasorum infection in housedog in Hungary. In gardens, where infected dogs were being kept 91 specimens of 6 species of limacid and arionid slugs were collected of which 5 specimens of Arion lusitanicus were found to carry larvae of A. vasorum. Dogs usually do not ingest such large slugs willingly. Frogs are known to act as paratenic hosts in the life cycle of A. vasorum. Since one of the infected dogs harboured also infection with the intestinal trematode Alaria alata, of which frogs certainly play the role of the second intermediate host, therefore it is assumed that in this case the dog became infected with A. vasorum by eating frogs.
在对匈牙利巴兰尼亚州（Baranya County）狗进行的寄生虫学调查过程中，在两只无症状的狗中发现了血管圆线虫（Angiostrongylus vasorum）感染。寄生虫的鉴定基于从粪便中分离出的第一期幼虫（L1）的形态，并且成功地用第一期幼虫对实验室饲养的圆斑盘舌轮虫（Discus rotundatus）和福寿螺（Lissachatina fulica）进行了实验感染，以排除具有与血管圆线虫相似幼虫的丝虫科（Filaroididae）物种。虽然血管圆线虫病在狐狸中广泛存在，但这是匈牙利首次报告在犬中感染血管圆线虫。在花园里，被感染的狗被饲养，共收集了 6 种 Limacid 和 Arionid 鼻涕虫的 91 个标本，其中 5 个 Arion lusitanicus 标本携带血管圆线虫幼虫。狗通常不愿意吞食如此大的鼻涕虫。已知青蛙在血管圆线虫的生活史中充当副宿主。由于其中一只感染的狗还感染了肠道吸虫 Alaria alata，而青蛙肯定是其第二中间宿主，因此可以假设在这种情况下，狗是通过吃青蛙感染了血管圆线虫。
