Alariasis of carnivores and its emergent form in human

Abstract

The results of studying about the spread of alariasis exciter – trematoda Alaria alata in Sumy region (the northeastern region of Ukraine) are represented in the article. Posthumous diagnosis method was used for the research; it is based on the helminthological dissection of the intestine. This method was applied to 151 dogs, 45 foxes and 3 wolves. The determination of revealed helminthes was hold in the laboratory of parasitology in Sumy National Agrarian University and in the department of parasitology in І. І. Shmalhausen Institute of Zoology of the National Academy of Sciences of Ukraine. There were no dogs infected by аlaria. Their helminthofauna is represented by the species: Echinococcus granulosus (Batsch, 1786), Taenia hydatigena (Pallas, 1776), Taenia pisiformis (Bloch, 1780), Hydatigera taeniaeformis (Batsch, 1786), Dipylidium caninum (Linnaeus, 1758), Toxocara canis (Werner, 1782), Toxascaris leonina (Linstow, 1902), Uncinaria stenocephala (Railliet, 1884). Among 48 wild predatory animals, 12 were infected by A.alata. The extensiveness of invasion was 25 %. The exciter of аlariasis was registered in 100 % of wolves and 20 % of foxes. The intensity of invasion in wolves was 15 – 67 cases, in foxes from 4 till 30. The results of the helminthic autopsy of carnivores from the northeastern region of Ukraine demonstrate significant spread of alatiasis among wild carnivorous (foxes and wolves) and its absence among domestic animals. The fact which was revealed by us about the lack of alaria among dogs in mentioned region and its rare registered cases in the same animals from other regions, causes the need for more detailed study of the spread of alariasis among domestic predatory in all regions of the country.
