[Adhesive and other properties of Vibrio cholerae tcp+ ctx- isolated from environmental objects in the Rostov region in 2002].

The adhesive, hemolytic and triacylglycerol lipase activity of 4 V. cholerae ctp+ ctx- cultures, sensitive to bacteriophage ctx+, isolated from the Don and sewage water were tested. All these cultures were found to induce hemolysis of sheep red blood cells in the Greig test in 2 hours, possessed triacylglycerol lipase activity, but had no adhesive properties.

[Role of lectin (hlyA) in the hemolytic and hemagglutinating activity of Vibrio cholerae].

Data on the nature of the substance which determines the structural gene hlyA in V. cholerae are presented. Computer analysis and experimental data on hemolysin preparations and V.

Using collision-induced dissociation with corrections for the ion number of degrees of freedom for quick comparisons of relative bonding strength.

The number of degrees of freedom-dependent stability of ions and ion-neutral non-covalent complexes under collision-induced dissociation (CID) conditions was studied in a quadrupole ion trap mass spectrometer. It was found that the stability of ions as probed by energy-variable CID has a linear dependence on the total number of degrees of freedom for the ions (or ion-neutral complexes) with the same (or nearly the same) bonding energy. The slope of such a stability vs number of degrees of freedom dependence correlates with the binding energy.

[Experimental evaluation of efficacy of Lactobacilli in prophylaxis and treatment of cholera].

Investigations on experimental models of cholera ("sealed" mice and suckling rabbits) demonstrated that previous daily oral administration of the ferment culture of Lactobacillus acidophilus BKM B-2020[symbol: see text] in a dose of 3.0 x 10(8) microbial cells/ml daily for 5-7 days prevented to the development of Vibrio cholerae infection. The curative effect observed after 3 administrations of lactobacilli within 48 hours after infection with V.

[Bactericidal properties of the Vibrio cholerae non O1 bacteriolysin].

The influence of the preparation of hemocytolysin, obtained from V. cholerae non O1 (strain P-11702), on the growth of V. cholerae cells was studied.

[Bactericidal properties of hemo-cytolysin from Vibrio cholerae non O1 P-11702 strain in a panel of indicator cultures for detection of vibriocins].

The influence of the preparation of hemo-cytolysin, obtained from V. cholerae non O1 strain P-11702 and inducing lysis of both red blood cells and V. cholerae cultures using a panel of indicator cultures for the detection of vibriocins, was studied.
