[Investigation of the antiparasitic activity of paracels series apparatuses].

The paper provides a preliminary positive assessment of the results of experimental studies of the inactivating effect of a bioresonance technology against Lamblia cysts and Cryptosporidium oocysts placed in the aquatic environment in vitro.

[Expected epidemic risk from the minimum drinking water content of protozoan agents of enteric parasitic diseases].

The paper presents information on lambliasis and cryptosporidiosis outbreaks associated with drinking water contamination-associated. It discusses a risk for the emergence of mass outbreaks of lambliasis and cryptosporidiosis among the population of the municipalities of administrative district centers and other human settlements, which are to exercise sanitary and parasitological control over the quality of water of its centralized drinking supply. The significance of this water contamination by lamblia cysts and cryptosporidium oocysts is considered.

[Water and intestinal parasitic diseases].

The paper presents data on the rates of Lamblia cyst dissemination of surface water sources in foreign countries, the Russian Federation, Moscow, and the Moscow Region. It shows a role of drinking water in the spread of intestinal parasitic diseases. In accordance with parasitological parameters, specific data on improvement of methodological control of water quality are presented.

[The role of the water factor in the dissemination of Toxocara eggs and the spread of toxocariasis in a megalopolis].

The water factor in transfer of the activators toxocariasis was not taken into account by parasitologists earlier. Yet in the urbanized ecosystems (first of all--in the megalopolis) it can have rather appreciable importance in distribution of toxocariasis in animals and man. Our researches which have been carried out in reservoirs of Moscow with the "wild" and the "organized" beaches, have revealed various, but as a whole their significant, of contaminations by invasion eggs Toxocara (Toxocara canis, T.

[The spread of the principal socially important parasitic disease on the territory of the Chukot Autonomous Okrug (ChAO)].

The paper provides the examination findings of helminthiases in the population of the town of Anadyr, the settlements of Kanchalan, Krasneno, and in the reindeer-breeding teams of the Anadyr District, CAD. The children infected with enterobiasis were shown to amount to 15.1 to 22.

[Ecological and hygienic conditions in the use of sewage sediments in agriculture].

Exposure of humans to heavy metals and helminthic eggs during agricultural utilization of sewage sediments is discussed. Recommendations for reducing or completely eliminating the risk of human exposure to heavy metals are offered.

[The sanitary parasitological characteristics of different sources of drinking water supply].

In some CIS areas (Khabarovsk Territory, Moscow, Grodno, Odessa, Astrakhan, and Kzyl-Orda provinces), sewage, animal sewage, and sewage from the populated areas (82.3% of the samples tested), water in the surface reservoirs, sources of potable water supply (54.0%), and potable water (6.

[Sanitary parasitocenology. The subject, goals and tasks].

The necessity for developing a new parasitological discipline, such as sanitary parasitocenology, is evidenced. Training of specialists with a wide range of parasitological knowledge and goal-oriented complexation of the investigations of parasitologists of different profile are shown to be required. The necessity for elaborating the measures for disinfection of environmental objects is shown taking into account the degree of pathogenicity of each parasitocenosis.

[Current status and tasks of sanitary-protozoological studies of drinking water (review of the literature)].

Occurrences of giardiasis in the USA, Canada, Great Britain and other countries caused by drinking water were noted. Necessity of sanitary-and-protozoological inspection of the drinking water in the USSR was demonstrated.

[The detection of opisthorchiasis foci in Byelorussia].

Local foci of opisthorchiasis have been established on the territory of 3 Belorussian districts (Brest, Gomel and Grodno provinces). Human beings, cats, fish and the first intermediate host mollusk invaded with Opisthorchis have been found.

[Seroepidemiologic characteristics of opisthorchiasis foci with various endemic levels].

Combined coprological (by an ether-formol method) and serological (by solid-phase enzyme immunoassay--EIA) screening of the population to detect opisthorchiasis was performed in the settlements situated in the Ob, Dnieper and Northern Dvina basins. Disease rate in the hyperendemic area on the Ob exceeded 80%, by the results of coprological population screening, while annual infestation rate established on the basis of specific antibodies determination in the blood was 70%. Infestation and disease rates in mesoendemic area, at the Ob tributary and in the Dnieper basin were practically equal and accounted for 30-40%.
