Parasitocenosis of the American mink at the urbanized ecosystems of Kirov region

In the territory of the Kirov region in 2011-2017, 39 individuals of the American mink of the urbanized territories of Kirov city and other settlements of Vyatka-Kama interfluves were investigated by the method of complete helminthological autopsies. The infection extensity with helminthes of the American mink is 92.3%. Helminthofauna is represented by seven species from two classes: Trematoda and Nematoda. Aonchotheca putorii dominates the parasitocenosis of the American mink, an abundance index of 73.2 specimens. Four species of helminthes were found in females: Alaria alata (larvae), Isthmiophora melis, Aonchotheca putorii, Capillaria mucronata. Intensity of infection A. putorii and I. melis significantly exceeds in males that of females (t=5.1, P >0.999 and t=2.3, P >0.95). The intensity of infection with helminthes is significantly exceeds in young American mink that of adults (t=2.4, P>0.95 и t=2.5, P>0.95). Epizootological and epidemiological significance are Alaria alata (larvae) - EI 43.6 ± 0.8% and Trichinella nativa (larvae) - EI 5.1±0.85 %.
