Considerable data concerning the physiological activities of strains of Staphylococcus aureus have been accumulated1-4; but the exact mechanism by which staphylococci are able to cause disease is still not understood. It is assumed that, in most situations, the pathogenicity of different strains of this group of microorganisms can be correlated with their biochemical activities. Staphylococci are able to produce in vitro, and also in vivo, a variety of substances, many of which at one time or another have been implicated as active principles connected with virulence. These substances vary considerably in antigenicity, and no absolute correlation has been demonstrated between pathogenicity and any one specific factor. However, there is much evidence to show that the more pathogenic strains produce free coagulase, ferment the carbohydrate mannitol. produce phosphatase, and develop pigment. Many of them also produce a variety of toxins, notably: lethal factor, dermonecrotoxin, the classical α-hemolysin, and leukocidin. More
