Nasal carrige of Staphylococcus was studied in relation to its significance as a source of the Staphylococci that caused hospital-acquired infection.

The number of penicillin resistance of S. aureus were 11 (84%) in college students and 16 (94%) in hospital personnel. The number of strains of penicillin resistant S. aureus which produced 13-1actamase were 9 (82%) in college student and 14 (88%) in hospital personnel. Methicillin-resistant S. aureus (MRSA) which showed resistance to erythromycin and penicillin G were 100%, tetracyline, cephalothin and clindamycin were over 40% respectively, gentamicin 20%, SAM 20% and chloramphenicol 0%.
