[Tick-borne borreliosis in the Iaroslavl region].
The present paper characterizes a natural focus of tick-borne borreliosis in the Yaroslavl Region, analyzes the incidence of this infection in the Region, and thus concludes that the density of the population living in the areas of the natural foci of tick-borne borreliosis has a significant impact on its epidemic process. The incidence of tick-borne borreliosis in the Yaroslavl Region has remained a challenge in the past 7 years. By the number of cases, this infection heads the list of naturally focal infections recorded in the Region. Examining long-term changes in the incidence and prevalence of tick-borne borreliosis in the Region revealed its high incidence in the population residing in the tidal marshlands and forest areas. At the same time the potential activity of natural foci of borreliosis due to the conditions that maintain the population of Ixodes ticks is high in the forest-field, southern, and meadow-forest-field regions.

[Current epidemiological surveillance of tuberculosis].
Some present-day specific epidemiological, microbiological and clinical features of tuberculosis are presented. A variant of the epidemiological surveillance morbidity scheme, comprising 3 blocks, viz. information, analysis and management, is proposed. In the information block the basic data necessary for epidemic analysis is listed, while the diagnostic block contains the stage-by-stage analysis of the information block data. In the block of management decisions the main directions of the tuberculosis prophylaxis interventions are listed.

[Approach to evaluation of the indicators of Yersinia infections in reactive and rheumatoid arthritis].
A total of 140 patients with reactive arthritis due to Yersinia infection were under observation for 2-10 years. A group of 104 patients with erosive rheumatoid arthritis served as control for analysis of the results of bacteriological and serological studies. The bacteriological analysis of the feces, urine, smears of the feces and blood were made repeatedly. As established the articular syndrome in reactive arthrosis has its specific features depending on the nature of the pathological process: primary, recurrent and chronic. Patients with primary reactive arthritis exhibited recovery without residual phenomena and relapses in 35.8% of the cases; in 86% the disease relapsed; in 36% it was chronic, persisting for a number of years as a non-erosive seronegative arthritis; in 25.3% arthralgia persisted; in 6.2% the clinical picture of secondary osteoarthrosis developed; in 17.3% the disease changed into spondyloarthritis and in 1.2% of the cases it changed into RA. Since in reactive arthritis Yersinia infection was confirmed in 48.5% of the cases and in RA in 14-21%, laboratory diagnosis cannot serve as an absolute criterion for reactive arthritis. It is necessary to take into consideration the anamnesis and the peculiarities of the clinical picture and the course of the articular syndrome.

[Contamination of milk and milk products by Yersinia enterocolitica at stages in the technological process of their production and manufacture].
Contamination of milk and its products with Yersinia enterocolitica at various stages of the production process was studied for the first time. Yersinia were detected in fresh milk (at dairy farms, in tanks at reception compartments of dairy plants) and in pasteurized milk (in tanks at the plant, in paper-bags on sale). All Yersinia strains isolated from milk are pathogenic for man and highly resistant to antibiotics. A possible role of man, in particular of workers at dairy farms and plants, in Yersinia dissemination, is shown. Unlike milk, sour milk foodstuffs virtually do not participate in propagation of the infection.

[The epidemiology of Yersinia infections in the central taiga subzone of the eastern European plain].
The seroepidemiological survey of the population in four southern regions of the Komi Republic for the presence of pseudotuberculosis and enteric yersiniosis was carried out. The survey revealed a high level of seroconversions to with respect to enteric yersiniosis (26.2 +/- 2.7% with the average antibody titer being 2.6 +/- 0.2 log2) and rare contacts of the rural population with Y. pseudotuberculosis (0.4%). Moreover, the intensity of contacts of the population with the infective agent was found to be closely related to the type of cattle breeding farms: the highest level of the immune stratum (32.2%) was registered among those persons whose residence was situated near large cattle breeding complexes. The prevalence of Y. enterocolitica, serovar 0:5, has been noted: to this serovar 87% of all positive reactions were obtained. The study of medical histories revealed that is some cases the disease manifested itself in the form of acute gastroenteritis.

[Bacteria of the genus Aeromonas as the causative agents of saprophytic infection].
The bacteriological study of feces from 458 patients with acute enteric diseases revealed that in 3.2% of cases (in summer in 8.1% of cases) the disease was caused by Aeromonas. In Aeromonas strains isolated from river water in the Volga delta, from fish and from raw meat the same pathogenicity factors occurred as in strains isolated from patients (hemolysin, DNA-ase, protease, lecithinase, amylase, adhesins, capacity of binding Congo red).
