Animal echinococcosis environmental features distribution in the Altai region

Echinococcosis, according to the World Health Organization, is one of the most socially significant problems of the population. According to Rospotrebnadzor, over the past 25 years, the incidence of echinococcus in Russia has tripled. A person becomes infected with echinococcosis through contact with invasive animals after hunting during skinning and processing, from invasive dogs and through water and food. The purpose of research is to study the distribution of animal echinococcosis in the Altai Region. Objectives: to study the features of the epizootology of larval and imaginal echinococcosis in animals. For helminthoscopy, fecal samples were taken from 68 dogs of different breeds and age groups. Infection of animals with larval echinococcosis was studied at slaughter and according to the data of laboratories of veterinary and sanitary examination, while taking into account the species, age, and economic affiliation of animals. During a scatological examination of 68 dogs, eggs or segments of echinococci were found in 4.5 % of cases with an intensity of invasion from 37 to 312 helminths per dog. Guard dogs with infested echinococci - 8.5 %, hunting dogs - 2.1, yard dogs - 5.7 %, respectively. In foxes, 15 species of helminths were found. In small cattle, young animals under the age of 1 year are infected - 2.6 %, up to 3 years - 6.7 and older than 3 years - 7.1 % of cases. The main distributors of echinococcosis are dogs, especially shepherds and strays, the infection of which is higher than dogs for other purposes. Wild carnivores can play a certain role in this, since up to 115 copies of cestodes were found in individual animals.
