The present study reports for the first time on the helminth species occurring in the gastro-intestinal system of fat dormice (Glis glis) in Croatia. Out of 55 dormice, 63.7 % harboured helminths belonging to two species, the nematode Paraheligmonina gracilis (syn. Longistriata elpatievskii) (Heligmonellidae, Trichostrogyloidea) in the prevalence of 52.7 %, and the cestode Hymenolepis sulcata (Hymenolepididae, Cyclophyllidea) in the prevalence of 32.7 %. Concurrent infections of both parasites were found in 12 fat dormice, P. gracilis alone was detected in 17 hosts and H. sulcata alone in 6 samples. No influence of parasitic infestation on animal weight was observed. Glirid helminths do not represent zoonotic pathogens despite the fact that dormice occasionally inhabit cottages and village houses, and are used in human nutrition.
Fascioloidosis is a parasitic disease of primary wild and domestic ruminants, caused by a digenean trematode, Fascioloides magna. The final hosts of F. magna are divided according to the host-parasite interactions into definitive, dead end and aberrant. The clinical appearance, pathology, outcome of disease, and its importance in disease epidemiology vary with different host types. According to this division, wild boar (Sus scrofa) are characterized as a dead end host. In this paper we analysed 12 wild boar livers from Croatia. Eleven of them contained pigment traces, pseudocysts, degrading pseudocysts, fluke migratory channels, live and degrading flukes. F. magna eggs were found in pseudocysts, but no eggs were recovered from faeces. Concurrent infection with F. magna and Fasciola hepatica was detected in one liver. According to everything we observed, wild boar currently has no direct role in maintaining and spreading the disease.
