Occurrence of internal parasites in stone martens (Martes foina) from Cracow and suburbs.
The pine marten Martes martes and the stone marten Martes foina are the only representatives of the genus Martes in Poland. During the last few decades, an intensive synurbisation of stone martens has been recorded. The aim of the study was to assess the level of infection by internal parasites of Martes foina in the Cracow urban area. Eleven necropsies were performed of stone martens killed during animal-vehicle collisions. Additionally, coprological examination of 129 stone marten scats was included. For further analysis, two standard methods, i.e. flotation and decantation, were used. The intensity of infection by parasites was low. Taenia martis was found to be present in one marten individual by necropsy, while Taeniidae helminths and two genera of nematodes, Capillaria and Toxocara, were identified during coprodiagnosis. The diet analysis of stone marten scats revealed a high proportion of two food categories. Percentage frequency of occurrence for plant material and anthropogenic was calculated as 42.3% and 15.4%, respectively. This type of food composition might suggest lower infection by internal parasites in particular species, especially with an indirect life cycle.
