A fluorescent chemosensor based on the 3,3′-bis(dipyrrin) bearing two chromophoric dipyrrin units was synthesized, which showed a strongly enhanced fluorescent intensity in the presence of Zn2+ ions and a high selectivity toward Zn2+ ions over a wide range of tested metal ions in organic solvents.
Results of analysis of cholera outbreak during which V. cholerae O1 biovar El-Tor ctxAB- tcpA+ was isolated from 2 patients and 30 carriers are presented. Epidemic was caused by contamination of water source and water route of transmission. Strains identical to ones detected in humans were isolated from water of surface well in zone of water intake.

Analysis of antibioticograms of 390 O1 and O139 serogroup Vibrio cholerae strains isolated from humans within 1927-2005 in various regions of the world showed that the strains of V. cholerae isolated within 1927-1966 were susceptible to 22 antibacterials, the strains isolated within 1938-1993 possessed 1-3 resistance markers and the strains isolated within(More)
The dynamics of the isolation of V. cholerae cultures from various water objects on the territory of Rostov-on-Don during the period of 1994-2001 was analyzed and biological properties of 14 such cultures were studied. In the absence of epidemic complications during the above-mentioned period, a growth in the amount of V. cholerae isolates, serogroups 01(More)
Activity of 16 antibacterial agents against human isolates of Vibrio cholerae O1 and O139 serogroups (P-5879, 4990, 143/23, and MO-45, P- 16065 respectively) was studied in vitro. The efficacy of the agents was studied in a model of generalized cholera in albino mice. Susceptibility of Vibrio cholerae P-5879 (used as the control) in the in vitro experiments(More)
