A faecal analysis of helminth infections in wild and captive wolves, Canis lupus L., in Poland.

摘要

One hundred and three samples of faeces of reared grey wolves from four locations (Stobnica Park and Zoological Gardens in Bydgoszcz, Wroclaw and Cracow) and twenty-six samples of faeces from two free-roaming packs of grey wolf (Canis lupus L.) in Pila (Forest Divisions: Borne Sulinowo, Czarnobor, Jastrowo) and Zielona Gora (Forest Divisions: Torzym, Krosno Odrzanskie) were collected between 2005 and 2007. Helminth eggs were detected in 78.6% of faecal samples of reared grey wolves and in 88.4% of those of free-roaming wolves. The trematode Alaria alata (80.1%) and nematodes Eucoleus aerophilus (23.1%) and Spirocerca lupi (11.5%) were only detected from wild packs of wolves and the nematodes Ancylostoma caninum (35.9%), Trichuris vulpis (15.5%) and Toxocara canis (3.9%) were only detected from reared wolves. Differences were observed in the prevalence and composition of helminth fauna between reared and wild grey wolves and our results are compared with those from studies within Poland and elsewhere in Europe.Digital Object Identifier http://dx.doi.org/10.1017/S0022149X10000106
