LOYMOPOTENTIAL OF TREMATODIASES FOCI AND THE RISK OF INFESTATION FOR THE POPULATION IN THE BELAYA RIVER ECOSYSTEM

Abstract

Loymopotential of natural foci of opisthorchiasis, metorchiasis (Metorchis bilis) and pseudamphistomiasis determine risk of infestation for the population with these trematodiases. There is a focal system of combined natural foci of opisthorchiasis – metorchiasis (M. bilis) – pseudamphistomiasis in floodplain-river ecosystem of the Belaya River in the carry-over area of pseudamphistomiasis causative agent which enters the river course with a bleak population. There is a stable risk of infestation for the population with the agents of these parasites through when eating bleak (age group of fish from one to three years old and elder) caught in the river course (the combined area of the carry-over of the opisthorchiasis, metorchiasis (M. bilis) and pseudamphistomiasis causative agents).
