Abstract

A total of 298 slugs belonging to four species, Arion lusitanicus, A. ater, A. ater rufus and Limax maximus, were collected from six different localities within a radius of 30 km from Copenhagen and examined for naturally acquired Angiostrongylus vasorum infection. Overall, 28 slugs (9%) were infected, but the prevalence varied among the studied localities: Rude Forest (26%), West Amager Forest (18%), Jaegersborg Forest and Deer Park (8%), Frederiksberg Park (4%), Assistens Cemetery Park (0%) and Frederiksberg Botanical Garden (0%). Only third-stage larvae (L3) were recovered from the slugs, in numbers ranging from 1 to 392 per slug. Overall 82% of the infected slugs harboured fewer than 10 larvae and only 14% harboured over 100 larvae.
