The authors have modified the one-plate method for the detection of staphylococcal hemolysins. They recommend to use in this method a prepurified form of staphylococcal beta-toxin and of streptococcal CAMP-factor instead of the exclusively beta-tonin-producing strain of Staphylococcus aureus and instead of the intensively CAMP-test positive Streptococcus agalactiae strain, respectively. The authors determined concurrently staphylococcal hemolysins, using a three-plate method in which alpha-antitoxin was employed, to ensure a better evidence of alpha-toxin. A total of 494 staphylococcal strains were examined by both methods. Of this number, 446 Staphylococcus aureus strains were of diverse host origin and 48 were coagulase-negative staphylococcal strains. On the basis of the various hemolytically active staphylococcal toxins, the authors recommend the suggested modification of the one-plate method for their routine detection.
A modification of the "one-plate method" for detection of staphylococcal hemolysins has been described. Bacterial strains of Staphylococcus aureus, Streptococcus agalactiae and Cornebacterium pseudotuberculosis were replaced by their prepurified hemolytically active exosubstances: beta-toxin, CAMP-factor, and, the exosubstance of Corynebacterium pseudotuberculosis called COREX. By means of the modification described, exact detection of hemolysins in possible with staphylococcal strains producing one type of hemolysin as well as with strains producing a combination of hemolysins.
