Abstrait
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. By these parameters--atoxigenicity and the absence of adhesive properties--the isolated V. cholerae strains were characterized as avirulent and epidemically safe.
