Current state of chikungunya fever laboratory diagnosis (review of literature).

The article is about methods of chikungunya fever laboratory diagnosis. An algorithm for the study of biological material for the presence of antibodies against chikungunya virus and virus antigens is presented. The overview describes the information about commercial immunodiagnostic and genodiagnostic kits and their detailed specifications.

[Zika fever immunodiagnostics: overview of test systems.].

The threat of rapid spread of Zika virus beyond endemic regions has given rise to more research in field of epidemiology and clinic, as well as to the search for Zika fiver new diagnostic and preventive tools. Between 2013 and 2017 in Russia 18 cases of infection transmission by travellers were reported. Fever Zika reference monitoring center in Volgograd Research AntiPlague Institute (Volgograd, Russian Federation) provides counseling and methodological assistance on laboratory diagnosis and monitoring of Zika fever.

[IDENTIFICATION OF CAUSATIVE AGENTS OF GLANDERS AND MELIOIDOSIS BASED ON PRINCIPLES OF POLYPHASE TAXONOMIC APPROACH].

Aim: Determine an optimal set of the most effective methods of identification and intraspecies typing ofcausative agents ofglanders and melioidosis. Materials andmethods. Bacteriologic, immunochemical, molecular-genetic methods were used.

[The comparative evalution of informativeness of immunologic and molecular genetic methods and means during stages of specific indication of melioidosis agent].

The reference-center of monitoring of agents of glanders and melioidosis carried out testing of reagents kits for diagnostic of agent of melioidosis and other close-related species of Burkholderiae in vitro. At the stage of specific identification of pathogenic Burkholderiae the diagnostic possibilities of commercial and experimental kits of reagents for express- and rapid analysis were evaluated. The criteria of evaluation of diagnostic value of kits of reagents were sensitivity, specificity and time of implementation of studies.

Activity of some enzymes in the liver of experimental animals after treatment with the liposomal formulation of tetracycline and streptomycin.

A new method for obtaining the liposomal formulation of streptomycin and tetracycline is described in the present work. The physicochemical properties of this formulation were evaluated. We compared the effects of free and liposomal formulations from streptomycin and tetracycline on activity of liver enzymes in albino mice.
