The antibiotic sensitivity was determined by paper disc method for 102 strains of staphylococcus aureus isolated from the pus of surgical suppurative infections, and following results were obtained.
1. The percentages of sensitive strains among 102 strains against five antibiotics are as follows
7.8% against penicillin
73.5% against streptomycin
97.1% against aureomycin
91.2% against chloromycetin
90.2% against terramycin
2. Most of antibiotics show additive action by the combined use of them, and this action is marked for staphylococci isolated from un-treated patients rather than those of treated patients with penicillin, streptomycin, and their combination.
3. The combine action of penicillin and streptomycin is mostly additive to the strains isolated from un-treated patients, and mostly antagonistic to the strains treated with penicillin, streptomycin, and their combination.
