[Mass spectrometry virulence marker Vibrio cholerae.].

Identification mass-spectrometry of marker proteins of toxicity of V. cholerae for development the express of diagnostics of the causative agent of cholera on the basis of the computer analysis in the MALDI-ToF format of electronic profiles became the purpose of our research. Subjected to the computer analysis mass and spectrometer electronic passports 140 of strains of V.

[The analysis of level of total immunoglobulin E (IgE) in blood serum of patients with various types of disorders of carbohydrate metabolism and blood groups 0 (I), A (II) and B (III).].

The analysis was applied to indices of IgE-mediated immunological reaction (total IgE) in patients with disorders of carbohydrate metabolism and diabetes and different blood groups (AB0) (n=93). The coefficient of pair correlation established a direct relationship between blood group 0 (I) and risk of development of diabetes type II (r=0.8) and higher risk of development of diabetes type I in patients with blood group A (II) (r=1).

[POSSIBILITIES OF APPLICATION OF MALDI-TOF MASS-SPECTROMETRY FOR STUDY OF CARBOHYDRATE-SPECIFIC RECEPTORS FOR DIAGNOSTIC BACTERIOPHAGE EL TOR].

Aim: Study mechanisms of interaction of diagnostic bacteriophage El Tor with sensitive strain Vibrio cholerae El Tor 18507 using direct protein profiling, identification of constant and variable proteins, taking part in interaction of the phage and cell, as well as carbohydrate-specific phage receptors.

Materials And Methods: . A commercial preparation of cholera diagnostic bacteriophage El Tor, strain V.

[PROTEOMIC MASS-SPECTROMETRIC ANALYSIS OF FRESHLY ISOLATED ESCHERICHIA COLI STRAINS].

Aim: Time-of-flight mass-spectrometric analysis of colon bacilli populations freshly isolated from humans for identification of proteome markers, that are characteristic for hemolytic and non-hemolytic strains, E.coli--associants of opportunistic bacteria.

Materials And Methods: 20 strains of monopopulation of hemolytic E.

[The application of mass spectrometry technique MALDI-TOF for inter-specific differentiation of closely-related vibrio].

The study was targeted to apply mass spectrometry analysis for inter-specific differentiation of collection strains of representatives of genus vibrio and identification of comma bacilli extracted from samples of boat ballast waters. The samples consisted of 207 museum strains of cultures and 347 microorganisms from samples of boat ballast waters. The identification of microorganisms was implemented using MALDI-TOF mass spectrometers.
