title: Cross protection between a strain of Staphylococcus epidermidis and eight other species of coagulase-negative staphylococci.
abstract: Passive protective activity of rabbit antiserum prepared by a representative capsular type II strain of Staphylococcus epidermidis in mice was absorbed out with homologous capsular type strains of S. simulans, S. cohnii, S. xylosus, S. hominis, S. capitis, S. hyicus, S. haemolyticus, and S. saprophyticus in addition to the homologous strain. The minimum amount of the strains required for absorption differed greatly, depending upon the strain. No absorption of the activity was shown with a strain of capsular type I and III of S. epidermidis, S. simulans, and S. cohnii, and a strain of capsular type III of S. hominis. These results suggest a possible capsular type specificity in the cross protection between strains of S. epidermidis and other species of coagulase-negative staphylococci.
