[Serologic study of experimental cholera polymer antigen diagnosticums].

Aim: Evaluation of quality indicators of constructed cholera antigen polymer diagnosticums by using a complex of specific anti-cholera sera. MATERIALS AND METHODS. Cell lysates of cholera vibrio strains Vibrio cholerae cholerae 1395, V.

[Cholera vibrios lectins as main pathogenicity and persistence factors (biotechnological aspects of use)].

Literature data and results of our studies of lectins are analyzed in the review. All the leading pathogenicity factors of cholera vibrios that possess enzymatic activity--cholera toxin, hemolysin, neuraminidase, chitinase have several lectin domains, that determine not only their pathogenetic role but also open perspectives for their use in medical practice. At the same time the variable receptor profile of cholera vibrios cells of various biovars and epidemical significance established with hemagglutination inhibition reaction by carbohydrates could be used to develop new principles of testing and typing of cholera vibrios.

[Design of a polymer drug for serological diagnosis of hepatitis C].

A new immunobiological polymer drug has been designed for the serological identification of hepatitis C. The drug is able to reveal specific antibodies in the sera of patients with hepatitis C, meets the current requirements of diagnostic test systems, and shows a high sensitivity and specificity. It is based on polyacroleinic microspheres; the concentrated cell culture biomass of hepatitis C virus (HCV), which contains an adequate set of viral antigens, is used as sensitin.

[Comparative evaluation of protein hydrolysates in designing their based universal culture medium for the diagnosis of plague and cholera].

Various protein hydrolysates made in Russia and foreign countries were comparatively evaluated to use them to design a universal agarized culture medium for the diagnosis of plague and cholera. Pancreatic baker's yeast broth was found to be most effective among the test media.

[Evaluation of toxin producing abilities of non-O1/non-O139 serogroup Vibrio cholerae isolated from humans].

Aim: Determination of non-O1/non-O139 Vibrio cholerae toxin (CT) gene expression by using EIA, and biological effect of non-O1/non-O139 V. cholerae supernatant on cell cultures evaluation.

Materials And Methods: 39 V.
