Further studies on antigen variation in Staphylococcus aureus. 1981

A T Pereira

The plating of successive Staphylococcus aureus subcultures of daily transfers proved that discontinuous variation resembling a genetic mutation and selective outgrowth of the variant are responsible for antigen variation. Every subculture of S. aureus, when repeatedly transferred, contained a mixture of cells with original antigen 17 (or 13) and final antigen 1 (or 3) that are relevant for research, serological diagnosis, and epidemiological study of staphylococcal diseases.
