[(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.

[Dirofilariasis in the Moscow Region, a low disease transmission risk area].

The spread of canine and human dirofilariasis was first studied in the Moscow Region, a low disease transmission risk area. D.repens infestation was found to have a tendency to increase in Moscow residents with the imported cases being predominant.

[Formation of the synanthropic foci of dirofilariasis in Russia].

Investigation of the formation of urban synanthropic foci of dirofilatiasis in an area of large accumulations of dogs is of scientific and practical interest due to the increased number of infested inhabitants of large towns.

[Human dirofilariasis: diagnosis and the pattern of pathogen-host relations].

Until recently, there has been no consensus of opinion as to that D.repens females can develop in the accidental host (man). The role of man is regarded as a biological dead end for Dirofilaria that are unable to develop the adult stage; human Dirofilaria migration is considered to be larval by the type of larva migrans.

[Prevalence of human dirofilariasis in Russia].

The nature of regional zoning of the prevalence of dirofilariasis in Russia was first established and a map reflecting the structure of an area with the identification of three zones (low, moderate, and stable transmission risks) was drawn up. In Russia, natural and climatic conditions are favorable for the development of transmitting mosquitoes and larvae of Dirofilaria to the invasion stage in the body of the transmitter to the south of the latitude of 58 degrees north in the European part and Western Siberia and to the south of the latitude of 50 degrees north in the Far East. The region of dirofilariasis covers 53 subjects of the Russian Federation, in 39 subjects (including 29 in the European part and 10 in the Asian part) of which 564 cases of dirofilariasis were notified in 1915-2008.

[The first case of diagnosis of dirofilariasis from the microfilariae detected in the human subcutaneous tumor punctate].

The paper describes the first case of diagnosis of dirofilariasis from the microfilariae detected in the subcutaneous tumor punctate from a person who has the clinical manifestations of D. repens invasion and resides in the Saratov Region that is endemic in dirofilariasis. The fact of detection of microfilariae in the man undergone invasion is assessed not only as the first case in the lifetime diagnosis of the first case of diagnosis of subcutaneous dirofilariasis, but also as the first case of verification of that a female can achieve sexual maturity in the organism of an accidental host and its impregnation if there are even single specimens of both sexes, which is characteristic in human invasiveness.

[Human dirofilariasis in the Moscow region].

Dirofilaria repens Railliet et Henry, 1911 was for the first time studied in the Moscow Region where 11 patients (6 males and 5 females) aged 4-72 years were recorded in 2000-2002. The geographical distribution (the southern and south-eastern parts of the region) of local cases of dirofiliriasis, was observed. There was a relatively high rate of D.

[Clinical and parasitological diagnosis of human dirofilariasis].

The paper reports two new cases of human dirofiliriasis (its causative agent is Dirofiliria repens) with a rare clinical diagnosis of funiculitis of the right scrotal spermatic cord in a 12-year-old boy from the Tambov Region and of erysipelatous inflammation of the outer side of the right leg in a 68-year-old woman who resides in Moscow and lives in her country house in the Shakhovsky District, Moscow Region, in summer. Both cases of invasion are regarded as local. The bodies of the D.

[Dirofilariasis in the countries of the CIS: an analysis of the cases over the years 1915-1996].

A hundred and fourteen cases of subcutaneous dirofilariasis caused by Dirofilaria repens were described in the CIS in 1915-1996. The mean age of the patients was 38.4 years (from 3 to 70 years).

[The efficacy of the 1-day treatment of enterobiasis with medamine].

The Soviet anthelminthic agent medamine has been synthesized at the Institute of Medical Parasitology and Tropical Medicine, USSR Ministry of Public Health and the Institute of Plant Chemistry, Academy of Sciences of the Uzbek SSR and is produced at the Tashkent Chemical Pharmaceutical Plant. It is used for one-day treatment of enterobiasis which is to be repeated in 2-3 weeks. A daily drug dose is 10 mg per kg body weight, given 3 times a day after meals.
