[The variability of the biological characteristics of Vibrio cholerae isolated from environmental objects].
The study of the biological characteristics used for the identification of the species, biovar and serovar of V.cholerae O1 isolated from environmental objects on the territory of 8 regions of Ukraine for the period of 1974-1993 revealed the tendency towards an increase in the number of altered cultures. Phage sensitivity (60.7%) and capacity for agglutination with cholera species- and type-specific sera (24.6%) proved to be the most variable properties. Resistance to polymyxin (4.8%), the absence of hemagglutination with chick red blood cells (8.7%), the absence of diastatic activity (28.9%) were also detected. The study established that the temporal, ecosystemic and territorial geographical dependence could be observed in the character of variability of V.cholerae O1. The data thus obtained indicate the expediency of monitoring the dynamics of the properties of V.cholerae O1 in order to establish the relationship between its variability and the epidemic process.
