Assessment of the importance of certain properties for the virulence of Vibrio cholerae and the detection of their correlations

: The study of 65 V. cholerae strains and mutants with different biological characteristics has revealed that their virulence directly correlates with their sensitivity to diagnostic cholera phages, lecithnase activity, viability and inversely correlates with their hemolytic activity. The role of lecithinase activity in a number of properties linked with cholerigenicity has been shown. Inverse correlation between the hemolytic activity of V. cholerae and some properties of this organism has been detected. The characteristics under study have been divided into 3 groups in accordance with correlations between them.
