Biological characteristics of Staphylococcus aureus isolated from nude mice.
The characteristics of 50 strains of Staphylococcus aureus isolated from BALB/c nude mice (nu/nu, nu/+) with or without subcutaneous abscesses [13] were examined. All the 50 strains belonged to biotype B according to the classification by Hájek and Marsálek. All of them were phage typable, showing a single phage pattern of 52A/79/47/53/77/83A/85. The coagulase type was classified as VII. All of the 50 strains were highly sensitive to penicillin, methylphenylisoxazolyl penicillin, erythromycin, spiramycin, lincomycin, chloramphenicol, tetracycline, kanamycin, gentamicin and cephaloridine, but were resistant to sulfisoxazole. Two S. aureus strains isolated from the nostril and finger of one person working in the mouse colony were identified as the same biotype as the murine strains but different in phage type, coagulase type and drug resistance pattern.
