RESUMO
This article presents the results of a comprehensive survey of the burden of tick-borne infectious diseases (TBIDs) in the Altai region of Russia. Official data for TBID incidence were analyzed and 201 samples from patients with suspected TBID were studied. Furthermore, questing ticks and ticks recovered from humans were examined to estimate prevalence of TBID-causative agents. The Altai region was determined to have a heightened risk for TBIDs in Russia. The most epidemiologically significant tick-borne illness in this area is spotted fever group rickettsiosis, while nationally in Russia, the leading TBID is Lyme borreliosis. The prevalence of mixed infection was 12.4% among the studied cases. Additionally, the prevalence of poorly studied pathogens - Kemerovo virus (KEMV) and Rickettsia tarasevichiae - in ticks from the Altai region was determined.

The paper presents the data on the clinical course and laboratory diagnosis of Brill's disease in 30 patients. The absence of absolute and not infrequently basic and indicating signs of the disease as well as its frequent course in the presence of the concurrent diseases significantly hinder its clinical diagnosis, particularly at the initial stage of the disease. Unwanted clinical and epidemiological consequences could be avoided only in case of a constant medical alertness and understanding of specificity of the current course of Brill's disease as well as a provisional hospitalization within 5 days of all the patients with unclear diagnosis who have fever into the infectious department of a hospital.

The authors evaluate contemporary possibilities of clinico-epidemiological and laboratory diagnosis of intestinal yersiniosis in the clinical practice. Data are reported on infestation of the environment with yersiniosis pathogen in this territory and the clinical picture of gastrointestinal form of yersiniosis and its symptomatology that is of help in the diagnosis. Perfection of laboratory diagnosis is of great importance in this respect.

Methodological recommendations for plasma viscosimetry using different paper and polymer filters were elaborated. Standardization of the filters with crystalloid solutions was established to be advisable before plasma viscosity investigation. The viscosimetric characteristics of soviet and foreign filters were compared during work with donor's plasma. As a clinical trial of the method measurements were made of plasma viscosity in patients with virus hepatitis A, who were diagnosed to have the plasma hyperviscosity syndrome. It is recommended that during plasma (serum) viscosimetry, one should employ metal clamps for filters (prolongs) and filters with pores measuring over 0.65 micron in diameter.
