In order to know the multiple antibiotic resistance of isolated Staphylococci in the air of various places of Chungnam National University Hospital, 2, 679 bacterial strains were collected at the department of Microbiology, Chungnam National University School of Medicine, during July, 1979.
The isolation rate, biochemical character and antibiotic resistance of isolated Staphylococci were studied.
The results were summerized as follows:
1. The isolation rate of Staphylococci in the Hospital air were 16. 1%(432 strains out of total 2, 679 strains).
2. Coagulase activity of the isolated Staphylococci were positive in 314 strains out of 432 strains isolated(72. 7%). Among of coagulase positive strains, 126 strains fermented mannitol(29. 2% ).
3. In the coagulase positive and mannitol fermenter, the isolation rate of resistant strains by one antibiotic was 69. 1%(C. P. ), 57.9%(L. M. ), 35.7%(C. C. ), 31.7%(S. M. ), 22.2%(K. M. ), 19.8%(A. P. ), 11.0%(C. D. ), and 18.3%(G. M. ).4. The multiple antibiotic resistance of Staphylococci isolated were resistant to 9 antibiotics(l.4%), 8 antibiotics(6. 5%), 7 antibiotics(4. 6%), 6 antibiotics(5. 1%), 5 antibiotics(5. 3%), 4 antibiotics(8. 6%) 3 antibiotics(14. 1%), 2 antibiotics(15. 0%) and all antibiotics sensitive(19. 9%)
