[ASSESSMENT OF POTENTIAL RISK FOR CONTAMINATION OF SURFACE WATER RESERVOIRS BY PATHOGENS OF HUMAN PARASITIC DISEASES].

Sanitary and parasitological studies of the waste effluents and surface reservoir waters were conducted in the south of Russia. The efficiency of purification of waste effluents from the pathogens of parasitic diseases was investigated in the region's sewage-purification facilities. The water of the surface water reservoirs was found to contain helminthic eggs and larvae and intestinal protozoan cysts because of the poor purification and disinfection of service fecal sewage waters. The poor purification and disinvasion of waste effluents in the region determine the potential risk of contamination of the surface water reservoirs and infection of the population with the pathogens of human parasitic diseases.

[Malaria in the Rostov Region: retrospective analysis of the malaria situation in 1952-2007].

In the Rostov Region, no cases of local malaria transmission have been notified since 1958, but cases of import malaria are recorded every year. The region is one of malaria-susceptible areas in the Russian Federation, which is characterized by intensive migration, the malariogenic potential sufficient for local transmission (malariogenic index 1.2), and the optimum conditions for resurgence of malaria when it is imported. The prevention of undesirable consequences of malaria importation requires the strict monitoring of feverish patients, cohorts of high-risk patients who go for trips to malaria-endemic countries.

[Crimean hemorrhagic fever in the Rostov region: epidemiological zoning and the activity of natural foci]. / Krymskaia gemorragicheskaia likhoradka v Rostovskoi oblasti: épidemiologicheskoe raionirovanie i aktivnost' prirodnogo ochaga.

The epidemiological zoning of the territory of the Rostov region has been made with the use of the epidemic process patterns and the data indicating the links between the landscape and the natural focus of infection. The spread of infected ticks has been established. The participation of several carrier species in the circulation of Crimean-Congo haemorrhagic fever virus has been confirmed. The mosaic character of their distribution and different levels of their contamination is of great prognostic importance. These data will be used for the improvement of epidemiological surveillance in working out the tactics of epizootological surveys and organization of prophylactic measures.
