[ROLE OF ANIMALS AND HUMAN BEINGS IN THE SPREAD OF TRICHINOSIS IN THE KURSK REGION].

Trichinosis is natural focal invasion in the Kursk Region. Porkworms (Trichinella) circulate in natural biocenoses among wild carnivorous mammals, wild boars, and rodents. Trichinosis cases are recorded in synanthropic animals. Carnivorous mammals form the basis for the parasitic system of trichinosis. The animals are infected with Trichinella through carnivorism, necrophagy, and cannibalism. The transport Trichinella vectors, necrophagous insects, naturally play an insignificant role-in the spread of trichinosis. Trichinella infection in animals occurs more commonly through necrophagia and cannibaism during winter months. Not only animals, but also man, play a great role in the spread of trichinosis. Infested wild and synanthropic aninals inhabiting the Kursk Region may carry the risk for Trichinella infection in the population.

[Sanitary-and-parasitological characteristics of non-centralized water supply in the Kursk Region]. / Sanitarno-parazitologicheskaia kharakteristika netsentralizovannogo vodosnabzheniia naseleniia Kurskoi oblasti.

The paper presents the results of a sanitary-and-parasitological assessment of non-centralized water supply sources (shaft and pipe wells, spring cappings) for the population. It has been shown that the water of the wells contains helminthic eggs, the proportion of positive tests varies and depends on the improvement of a water source, on the presence of a sanitary zone, etc. The water on non-centralized water supply presents a risk for infection with intestinal parasitic diseases.

[Methodological assurance of natural and drinking water parasitic control]. / Metodicheskoe obespecheniie sanitarno-parazitologicheskogo kontrolia kachestva prirodnoi i pit'evoi vody.

The paper shows it necessary to exercise control over the quality of natural, waste, and portable water in terms of parasitological indices. The standard techniques of sampling and sanitary and parasitological studies of water, which allow water quality control to be effectively exercised in accordance with the current sanitary regulations, are considered.
