[(EXPERIENCE WITH GEOGRAPHIC INFORRMATION SYSTEMS USED IN EPIDEMIOLOGICAL STUDIES (AS AN EXAMPLE OF MALARIA AND DIROFILARIASIS)].

The effective application of GIS against parasitic diseases requires the patterns of spread of parasitic diseases in certain natural, climatic, and socioeconomic conditions of different regions where there are epidemically effective carriers. The epidemiological parameters defining a high risk of an epidemiological process after P.vivax importation into Russia were calculated using the developed HealthMapper controlled module with a database.

Dirofilaria immitis in a child from the Russian Federation.

An immature female worm, Dirofilaria immitis, was isolated from the scrotum of a 14-month-old child. This is the first identification of human dirofilariosis caused by D. immitis in a relatively Northern region (Moscow) of the Russian Federation.

[Human dirofilariasis: clinical and diagnostic signs and diagnostic methods].

The clinical and diagnostic signs caused by the tissue location and migration of adult Dirofilaria in the human body determine the use of different methods for the diagnosis of dirofilariasis. During their investigations, the authors modified polymerase chain reaction (PCR): they chose and synthesized primers and selected amplification regimens for them and obtained agarose gel bands that corresponded to PCR fragment length nucleotide sequences that were equal to 245 bp for D. (N.

[Entomological monitoring of an area to assess Dirofilaria transmission risk].

As the basis for entomological monitoring, the authors first propose to investigate the structure of a season of D. repens invasion transmission in the carrier in relation to the ambient temperature, such as onset of a transmission season, terminaton of mosquito infection, the number of invasion circulations. A calculating procedure has been developed.

[Results of studies of human dirofilariasis in Russia].

Human dirofilariasis is a pressing health problem in Russia. By 2014, there have been as many as 850 Dirofilaria repens-infested people living in 42 subjects of the Russian Federation. One of the favorable factors for circulation and spread of invasion is a temperature of above +20-24 degrees C; when the latter is maintained during at least 20 days there may be 1.
