[Echinococcosis in the Nenets Autonomous Okrug].

The paper presents results of an immunological screening of the population from the Nenets Autonomous Okrug of the Arkhangelsk region for echinococcosis. A high level (8.4 +/- 1.0%) of seropositivity of the population has been found to Echinococcus antigens. Occupational groups, such as reindeer-breeders, domestic servants in the tent of skins, hunters, fur-farmers, furriers) have been identified to be mostly at high risk for Echinococcus infection. Some animal species have been demonstrated to be implicated in the epidemiology of echinococcosis. The most likely source of human granulosus Echinococcus invasion is a dog whose mature Echinococcus infection rate is 5.8 +/- 3.2%, that of multilocularis Echinococcus is a polar fox whose infection rate is 40.3 +/- 4.3%.
