Infection of Salamandra salamandra larvae (Amphibia: Urodela) with the
fish acanthocephalan Pomphorhynchus laevis was detected in a fish-fre
e mountain brook. Gammarus fossarum was found to be the intermediate h
ost. The parasites were probably inadvertently introduced through fish
breeding practices. Evidence was obtained that Pomphorhynchus laevis
persists, at least for several months, in postmetamorphic fire salaman
ders.
