Antigenic studies on micrococci *

Micrococci seem to be organized antigenically in a similar way to staphylococci. Agglutinogens shared with Staphylococcus aureus and S. epidermidis, and a number of specific agglutinogens have been demonstrated. Two serologically specific teichoic acids were revealed by agar-gel precipitation. The results indicate that M. varians has erythrocyte sensitizing antigens, but not M. luteus, M. roseus, or M. conglomeratus. The other serologic examinations revealed no correlation to these biochemical types.
