Abstract
Objective of research: A study of the population structure of single helminth types in mixed infections of cattle within the Chechen Republic.
Materials and methods: Studies were carried out in 2013–2015 based on helminthological autopsies of 86 head of cattle of different age slaughtered in meatpacking plants or slaughterhouses of the Chechen Republic. Fecal samples were obtained from 105 calves and investigated by flotation method. To detect Cryptosporidium sp. Oocysts, a thin smear of animal feces was prepared, dried, fixed with methyl alcohol and stained with carbol fuchsin by Ziehl-Neelsen method.
Results and discussion: It was found that mixed helminthiases occur in 28,3 % of cows, 47,4 % of calves, 58,8 % of young cattle. The helminth population in young cattle was 2-3 times higher than that in adult cattle. Totally 378,7 helminth individuals were detected in young cattle, among them 28,4 % - Nematodirus helvetianus, 32,2 %- Paramphistomum cervi, 6,0 % - Trichocephalus ovis and 4,0 % - Trichostrongylus axei.
Keywords: cattle, mixed infection, structure of helminth species, Chechen Republic.
