Abstract


In accordance with the emergence of drug resistant strains of staphylococci, incidences of clinical infection due to resistant strains are increasing and, especially hospital infections have implied important signif cances from clinical viewpoint and this has teen studied extensively.
Along with the hospital infection, studies on distribution of pathogenic staphylococci among hospital environments are of practical importance for the illustration of mode of spread and route of infection by this organism.
In the present study, auther investigated the distribution of pathogenic staphylococci in hospital materials at Kyungpook University Hospital during 3 seasons of spring, summer and winter, from March 1966 to February 1967.
The results obtained are as follows:
1) Total mumber of isolated staphylococci was 758 strains during spring, summer, and winter seasons. Among them, 400 strains (52.7%) were coagulase positive, and more coagulase positive strains belong to summer strains than other seasonal origin
2) The highest incidence of coagulase positive strain was observed in dressing car regardless of season, and next were shoes and pillows, patient ward areas contained heavier organisms than out patient clinic generally, and nursery harbored higher rate in spring and decreased in summer and winter.
3) The sensitivity to antibiotics of isolated pathogenic strains was diverse in pattern, however, highly sensitive to albamycin erythromycin, kanamycin and neomycin but generally resistant to other 8 kinds of drugs.
4) Of the 400 strains tested, 80% of them were typable by standard phage set, among them 69 strain (17.2%) were belong to epidemic group.
Epidemic strains, with a few exception, exhibited a higher resistancy to antibiotics as compared to the non-epidemic strains, and more multiple resistant strains belong to epidemic strains in ratio.
5) The phage patterns of epidemic strain were following order in frequency 80, 80/81 and 52/52A/80.
