title: Dissections of fresh skulls confirm low prevalence of Troglotrema acutum (Trematoda: Troglotrematidae) in German badgers (Meles meles).
abstract: We examined 131 European badgers Meles meles (Linnaeus, 1758) from 67 localities in central Germany for the presence of the cranial trematode Troglotrema acutum, as previous studies based on museum skulls might have underestimated the prevalence of the parasite in this host. We detected the flatworm in only three individuals that originated from the Rhoen Mountains (Thurigina and Bavaria). While the cranium of one host individual showed the lesions and the sponge-like widening of certain regions of the skullcap that are typical of a T. acutum infection, the skulls of the two remaining badgers did not show any deformations. The three badgers were infected by eight, 20, and 49 T. acutum individuals, respectively. Eggs of the trematode parasite were detected in the paranasal sinuses of two badgers. While badgers infected with T. acutum may not show any surface bone lesions, the results of the present study do not contradict the conclusion that the badger is only an accidental host of T. acutum.
