[Epidemiologic characteristic of military unit location territories in Orenburg region].

The authors showed the real zoogenous infection hazard during the military units located in natural focus in Orenburg region. Among the zoonosis special place occupies the hemorrhagic fever with nephritic syndrome. The authors came to conclusion that months of seasonal pickup in Orenburg region are September - December, January of next year; in Totskiy region--November - February.

[Contamination of protozoa by enteroviruses in fresh water and sewages].

Aim: To determine rate of infection of protozoa by enteroviruses to assess the potential role of protozoa as a natural reservoir of enteroviruses.

Materials And Methods: The samples were collected from flowing and stagnant water reservoirs in Orenburg region in summer and autumn. The samples of sewages were taken in all stages of their treatment.

[The likely role of protozoa in the maintenance of the environmental circulation of enteroviruses].

The purpose of the study was to define the likely role of protozoa as a possible natural reservoir for enteroviruses and their involvement in enterovirus-induced serous meningitis morbidity. Samples were taken from the running and standing water reservoirs of the Orenburg Region in the summer-autumn period and those of wastewaters were collected at all purification stages. Enteroviral RNA in the protozoan cultured was detected by the reverse-transcription polymerase chain reaction (PCR).

[Algorithm for prediction of reconvalescent salmonellosis carriage].

Of total of 181 patients with Salmonella infection were examined by clinical and laboratory methods. As many as 124 indices characterizing biological properties of Salmonellae, a large intestine microbiocenosis status, systemic and local immunity, were investigated as well. Among these indices, the most revealing signs were defined to prognosticate the reconvalescent carrier state.
