title: The CAMP test performed by using Staphylococcus aureus sphingomyelinase (beta-haemolysin) and Clostridium perfringens lecithinase.
abstract: The CAMP test was performed by employing Staphylococcus aureus beta-haemolysin (sphingomyelinase) and Clostridium perfringens alpha-toxin (lecithinase) for identification of group B streptococci on blood agar, using blood from different origin. Partial purification of Cl perfringens alpha-toxin was carried out by means of sheep erythrocytes. With the toxin preparations described positive CAMP reaction was obtained only on sheep blood agar. False positives with regard to group A streptococci could not be avoided by either of the methods.
