ENVIRONMENTAL CONTAMINATION BY PATHOGENS OF GEOHELMINTHIASIS IN THE SOUTH-EAST OF THE KURSK REGION

Abstract

Geohelminth infections are a complex and multifaceted problem that attracts the
 attention of both medical doctors and veterinarians, as well as scientists. They
 are the most common parasitic diseases. The annual number of recorded cases
 of geohelminthiasis in humans in the Kursk Region and conditions conducive
 to their spread have determined the timeliness of studies on contamination of
 environmental objects with geohelminth eggs. Analysis of the study results showed
 that the contamination of environmental objects with parasitic agents was 8.4%.
 Ascaris and Toxocara eggs were recorded in the samples. 7.9% of the examined soil
 samples, 13.7% of the manure and 3.7% of the runoff samples from the territories
 were positive for pathogens of geohelminthiasis. Depending on the season of the
 year, the indicators of environmental objects contaminated with geohelminth eggs
 were not the same. There was an increase in contamination of the soil and runoff from territories almost twice in the autumn period (prevalence, 12.6%) as compared
 with the summer period (EO 6.5%). Thus, environmental objects contaminated
 by parasitic agents indicate the circulation of geohelminthiasis pathogens among
 domestic animals in the study territories and a risk of infection with larval toxocariasis
 and ascariasis for the population.
