Stichorchis subtriquetrus in European beaver from Croatia: first report

Since 1996, European beavers (Castor fiber) have been reintroduced from Germany to Croatia. However, little is known about the health status of the established population. Necropsy of a 2-year-old female European beaver, which died from a car accident, revealed 28 adult trematodes in the preserved fragments of the colon and in the peritoneal cavity. All of them were identified as Stichorchis subtriquetrus. The typical location of these parasites is the large intestine, and the finding of several specimens in the peritoneal cavity can be explained by the severe trauma. We assume that the trematode was introduced to Croatia along with the beavers. Furthermore, it is very probable that the life cycle can be completed as the intermediate hosts are part of the local fauna. This is the first record of S. subtriquetrus in Croatia.
