Staphyylococci are responsible for over 80 per cents of the suppurative diseases encountered in medical practice. They cause most suppurative infections of the skin but may also invade and produce severe infections in any other parts of the body. In order to know the carrier rate of staphylococci between the parahospital workers and in the hospital workers, the author undertook isolation of S aureus from nasal cavity on 68 cases of freshmen, 31 cases of sophomores, and 37 cases of juniors in Busan National University, and 30 cases of nursing students, 30 cases of nurses, 30 cases of nurses in charge of operating room and 30 cases of doctors in Busan National University Hospital. The tested total cases were 256 cases which were 136 Cases in parahospital workers and which were 120 cases in hospital workers. The biochemical characters of S aureus strains isolated were studied on coagulase test, mannitol test, hemolysis test and sensitivity test to antimicrobial agents. The results obtained were as follows: 1. S aureus were isolated 49 cases(29.7%) from nasal cavity parahospital workers and were isolated 67 cases(55.8%) from nasal cavity on hospital workers. 2. Among 40 strains of S aureus isolated from parahospital worker's nasal cavity coagulase positive were 29 cases(72.1%), and coagulase negative were 11 cases(27.5%). And mannitol positive were 29 cases(72.5%), and mannitol negative were 11 cases(27.5%). 3. Among 67 strains of S aureus isolated from hospital worker's nasal cavity coagulase positive were 59 cases(88.1%), and coagulase negative were 8 cases(11.9%). And mannitol positive were 49 cases(73.1%), and mannitol negative were 18 cases(26.9%). 4. The hemolysis test of each erythocytes on coagulase and mannitol positive S aureus isolated were sensitive to rabbit(40 cases: 81.6%), guinea pig(26 cases: 53.6%), sheep(13 case: 26.5%), and were not sensitive to chicken and human erythrocytes, respectively. 5. The hemolysis test of each erythocytes on 10 strains of coagulase and mannitol negative S aureus isolated were not sensitive to all of, erythrocytes. 6. The sensitivity test to the various chemotherapeutic agents was almost sensitive to the strains isolated from parahospital workers, but was almost resistant to the strains isolated from hospital workers.
