[Leptospirosis in the Southern Federal District of the Russian Federation]. / Leptospiroz v Iuzhnom Federal'nom Okruge Rossiiskoi Federatsii.

The retrospective and operative epidemiological analysis of leptospirosis morbidity on the administrative territories of the Southern Federal District during the period of 1990-2002 was carried out. The dynamics and tendencies of morbidity in individual administrative units of the region were shown. Materials on the negative influence of the emergency situation arising in the region as the result of the natural calamity in summer 2002 were presented. As shown in this work, timely decisions on the stabilization of epidemiological situation taken at the period of high flood and inundation in summer 2002 in the Southern Federal District and their efficient execution made it possible to keep the epidemiological situation in leptospirosis under control.

[Features of leptospirosis in the Krasnodar Territory]. / Osobennosti leptospiroza v Krasnodarskom Krae.

The data on leptospirosis morbidity in the Krasnodar Territory, one of the most epidemiologically unsafe areas in this infectious disease in the Russian Federation, are presented. High morbidity registered in this territory greatly depends on the epidemic outbreaks appearing due to defects in the realization of a complex of sanitary and veterinary measures. The Krasnodar Territory is liable to be affected by natural calamities. In 1997 a severe outbreak of leptospirosis took place here in connection with the high flood. Due to timely prophylactic measures the epidemiological consequencies of the similar calamity occurring in 2002 were brought to a minimum.

[Prevention of acute enteric infections and viral hepatitis A in the Krasnodar Territory appearing in connection with a natural disaster in 2002]. / Profilaktika ostrykh kishechnykh infektsii i virusnogo gepatita A v Krasnodarskom Krae v sviazi s prirodnym stikhiinym bedstviem v 2002 g.

Materials on the sanitary and epidemiological situation in the Krasnodar Territory in connection with emergency situations (intensive snowfalls, heavy showers, high floods) in 2002 are presented. The scope of the destruction of the systems ensuring the life provision of the population in the affected regions of the territory is shown. To carry out the epidemiological surveillance on acute enteric infections, to make corrections of the planned prophylactic measures, as well as the timely solutions of problems connected with controlling the epidemiological situation, the daily monitoring of the level and dynamics of infectious morbidity in individual settlements among different age and professional groups, as well as the foci of infections, was established. 65 cases of acute enteric infection and 4 cases of viral hepatitis A were registered in the affected areas, which did not exceed the average morbidity figures for many years. A complex of sanitary, hygienic and prophylactic measures was carried out by the sanitary and epidemiological service of the territory, which made it possible to maintain human morbidity in acute enteric infections and viral hepatitis A in the affected areas on the sporadic level.

[Causes of leptospirosis morbidity in Krasnodar region]. / Prichiny zabolevaemosti leptospirozom v Krasnodarskom krae.

The situation in leptospirosis morbidity in the Krasnodar Territory has been analyzed. The tendency towards a decrease in the number of water outbreaks and a growth in the number of sporadic cases has been noted. Antibodies to Leptospira ictrohaemorrhagiae, whose natural carriers are gray rats, are most often detected in the blood of patients. Among leptospirosis patients, persons engaged in fishing, work on plots of land adjoining their summer cottages, dog breeding are mostly registered. The detailed characterization of the outbreak of 1997, an outstanding outbreak among those observed in recent years, is given. This outbreak was caused by abundant precipitations and the subsequent flooding of vast areas, a growth in the number of Leptospira-infected rodents. In this connection attention is drawn to the necessity of greater efforts in carrying out deratization, as well as sanitary and veterinarian measures.

[Epidemiology and epizootiology of rabies in Krasnodar region]. / Epidemiologiia i épizootologia beshenstva v Krasnodarskom krae.

In 1995-1999 the aggravation of the epidemiological situation in rabies took place in the Krasnodar Territory. In the region of Great Sochi this was due to the emergency situation (armed conflict) on the adjoining territory (in Abkhazia), which led to the migration of domestic animals, turning wild, to the Black Sea coast where the situation with this infection had earlier been favorable. In 1995-1997 on the territory of Great Sochi 4 persons died of rabies as a consequence of getting dog bites and then failing to apply for medical assistance. A threat for human health is also created by cutting down work on the extermination of stray dogs and cats, the insufficient provision of medical institutions with antirabic preparations. The efforts of the medical service of the Territory should be concentrated on the prophylactic measures for controlling rabies.

[Pseudotuberculosis in the Krasnodar Territory. The clinico-epidemiological characteristics of its morbidity and the biological properties of its strains]. / Psevdotuberkulez v Krasnodarskom krae. Kliniko-épidemiologicheskie osobennosti zabolevaemosti i biologicheskie svoistva shtammov.

Group cases of pseudotuberculosis, first registered at health-restoring institutions of the health resort of Gelendzhik (the Krasnodar Territory), are described. The etiology of these cases of the disease was established on the basis of clinico-epidemiological data, specific seroconversion in 66% of the examined patients and the isolation of Yersinia pseudotuberculosis strains from the feces of four patients. The combination of signs observed in the isolated strains, viz. the presence of plasmids with molecular weights of 75 and 45 MD, resistance to bactericidal factors of normal human serum and autoagglutination in cell culture medium, made it possible to consider these strains to be virulent. The cases of infection were probably caused by the use of fresh cabbage salad. The study of 3,128 rodents caught in the Krasnodar Territory, including those caught in the area of the health resort, resulted in the isolation of 105 Y. enterocolitica strains and strains of 5 other Yersinia species, but not Y. pseudotuberculosis strains. The concept on the saprozoonotic nature of pseudotuberculosis was substantiated.

[The organization of an epidemiological surveillance of HIV infection in Krasnodar Territory]. / Organizatsiia épidemiologicheskogo nadzora za VICh-infektsiei v Krasnodarskom krae.

For the first time a case of AIDS was detected in the Krasnodar Territory of the USSR, and the presence of HIV infection in homosexuals, foreign students, and promiscuous persons was established. To study the spread of HIV infection, 5 diagnostic laboratories were created and 5 routes for the transportation of sera were organized. This permitted the screening of the population in 1988 with the complete coverage of groups to be placed under surveillance.

[Methodological approach to the evaluation of current sanitary conditions of water reservoirs in rural regions]. / Metodicheskie podkhody k otsenke sovremennykh uslovii formi- rovaniia sanitarnogo sostoianiia vodoemov se'lskikh raionov.

It is demonstrated that an increasing impact of anthropogenic factors becomes characteristic of the modern sanitary state of water reservoirs in rural areas. Priority indices of water quality in rural water reservoirs are proposed. Proceeding from the data thus obtained there is recommended a set of water-protective measures aimed at raising safety of water management conditions.
