[Helminths of wolves (Canis lupus) from south Mazurian Lakeland, a coprological study]

52 wolf scats collected during winter 2001/2002 in Puszcza Piska and Napiwodzko-Ramuckic forests were examined using Fulleborn's method. The overall helminth prevalence was 28.8%. Six helminth species were recorded, the most frequent species were Uncinaria stenocepmhala/Ancylostoma caninmu (treated together; found in 6 samples), Toxocara canis and Trichuris vulpis (both identified in 4 samples). The mean intensity of egg expulsion was 2.0 eggs/g feces, the most intense infection was this with Toxocara canis (average 23.0 eggs/g feces). There were observed differences in prevalence of parasite' species between packs. Present paper is first such an investigation in northeastern Poland.
