Fig. 1From: Nonhemolysis of epidemic El Tor biotype strains of Vibrio cholerae is related to multiple functional deficiencies of hemolysin AIdentification of the role of the hlyA gene in hemolysis of strain C6706. Deletion of hlyA from C6706 caused a negative result for strain CΔhlyA in the hemolysis test, and a positive was obtained when hlyA gene was complemented (CΔhlyA-C). Strain CΔhlyA complemented with the vector pBAD33 was used as the negative control, and 1% sheep erythrocyte LB solution was used as the blank controlBack to article page
