[Demonstration by electrosyneresis of 2 exfoliation serotypes produced by Staphylococcus aureus].

The method described allowed a rapid, easy and reliable detection of exfoliative toxin produced by Staphylococcus aureus. A new culture technique of S. aureus strains and the detection of exfoliative toxin by electrosyneresis are described. This could replace the new-born mouse test. Such a method was useful for epidemiological studies because a lot of strains of S. aureus could be screened for exfoliative toxin production; thus the serotype of the toxin (ETA or ETB) was also determined.
