[(INDUCED MALARIA)].

Induced malaria continues to be one of the most pressing public health problems in malaria-endemic countries. Ma- laria parasites remain viable in stored blood at a temperature of 2-6°C for 3 weeks. The paper presents current problems associated with transfusion-induced malaria. In the USSR and then in the Russian Federation, sporadic cases of induced malaria (Plasniodium vivax, P.malariae, rarely P.falciparum) were notified (230 cases in 1958 to 1990 and only 5 in 1991 to 2016). Current (immunological and molecular) methods for the laboratory diagnosis of malaria do not provide a 100% detection rMfteor its pathogens; therefore, it is necessary to search for highly efficient, rapid, and low-cost diagnostic methods to ensure the biological safety of donation.

[MALARIA IMPORTATION BY RUSSIA'S CITIZENS AND FOREIGNERS, INTO THE CITIES AND TOWNS OF THE RUSSIAN FEDERATION].

A total of 436 malaria cases, including 12 from the CIS countries and 424 from far foreign countries (of Africa and Central and South-East Asia), were imported into the Russian Federation in 2010-2014. Most (96.6%) cases were notified in the urban areas of 52 administrative subjects of Russia. The largest number of the imported cases were seasonal workers (39.2%), tourists (31.3%), students and foreign postgraduate students (19.5%), and ship or aircraft crews (10%). During a short malaria transmission season (June to August), there were 150 cases of different types, out of them there were only 63 cases of tertian malaria (its pathogen is Plasmodium vivax, to which malaria mosquitoes of Russia's fauna are susceptible). The relatively small number of infection sources in the short transmission (June to August) season of malaria, its importation into low-susceptibility large towns, and a small proportion of imported vivax malaria cases substantially reduce the risk of malaria in the highrisk areas of the country.

[The current malaria situation in the CIS countries (2011-2012)].

In the last 3 years, the malaria situation has considerably improved in the CIS countries: Three CIS countries, such as Turkmenistan, Armenia, and Kazakhstan, received the malaria-free status (in 2010, 2011, and 2012, respectively) confirmed by the WHO certificate; Azerbaijan, Kyrgyz Republic, Uzbekistan, and Tajikistan are in the elimination period. Despite the continuing intensive migration of CIS citizens to Russia, its malaria situation has been favorable, which is associated with the significant reduction of imported infection cases among migrants.

[First evidence for breeding Aedes aegypti L in the area of Greater Sochi and in some towns of Abkhasia].

A preliminary survey of some widely spaced settlements in Greater Sochi (and in the city of Sochi) in a period of late July to early October 2007 has revealed man-biting females and swarming males of Aedes aegypti females indoors and outdoors. Man-biting Ae. aegypti females, like males swarming nearby, were also present in the town of Gudauta under study in September (the males and females of this species were found on one-day youngsters in the animal houses) and in the suburbs of the town of Sukhumi (Republic of Abkhazia). Ae. aegypti breeding places and larvae were revealed at the back of houses in Gudauta. Detection of not only males, but also females and preimagoes of this species suggests that a local breeding Ae. aegypti population is available in this area. The findings show that a local breeding population of Ae. aegypti mosquitoes has reemerged in the inspected area of the Black Sea coast (Tuapse-Sukhumi) with a humid Mediterranean climate after 35-40-year absence. Prevention of outbreaks of menacing human arbovirus diseases in the importation of their pathogens to the health resort-tourist area of the Caucasian Black-Sea coast requires urgent organization of a continuous entomological service for environmental monitoring, organization, and implementation of measures to eradicate Ae. aegypti.

[Role of parasitological laboratories in sociohygienic monitoring].

The data available in the 2003-2004 statutory forms of the Russian Federation's subjects show that the parasitological laboratories of state sanitary surveillance centers in the Russian Federation make little use of sanitary-and-parasitological studies during sanitary monitoring. Studies of the parasitological indices of foodstuffs, drinking water, wastewater and their sediments are not under way in some regions. There is a poor material and technical basis in the parasitological laboratories; the work of parasitological laboratories does not meet the requirements stipulated in Sanitary Regulations 1.2.731-99 "Safety of work with microorganisms of pathogenicity groups 3-4 and with helmints". Intralaboratory monitoring is not always under way in the parasitological laboratories. Highly skilled staff is lacking. It is necessary to extend the list of sanitary-and-parasitological studies in accordance with MU 3.2.1756-03 "Epidemiological surveillance of parasitic diseases".

[Treatment experience with biltricide in a natural focus of opisthorchiasis]. / Opyt lecheniia bil'tritsidom v prirodnom ochage opistorkhoza.

Since 1992, a total of 72 opisthorchiasis patients have been treated with biltricide in the outpatient setting, with laboratory pre-examination of their blood organs. The treatment was made in a course dose of 60 mg/kg body weight during a day. On the following day the patients underwent duodenal probing to remove parasites. Adverse reactions as giddiness were noted in 9 patients. The efficiency of the therapy was monitored 3 months later, the control analysis detected no Opisthorchis eggs in 96% of the patients. The outpatient use of bilthricide indicates its high efficiency in the treatment of opisthorchiasis if the following requirements are met: preparation of patients, drug taking in the presence of a medical worker.
