[Differentiation of cholera and NAG vibrios by their virulence].

The method for differentiating cholera and NAG vibrios by their virulence is proposed. This method is based on the evaluation of the following characteristics: hemolytic activity and sensitivity to phages C and Xdf-5, the vibrios being cultivated in 1% peptone water with 1% of glycerol (for the determination of hemolytic activity) and in 1% peptone water with 1% of barium chloride (for the determination of sensitivity to phages).
