[Sensitivity of bacteria to chemotherapeutic agents (Zurich 1980). Part II. Bacteria isolated from outpatients].

The frequency with which grampositive and gramnegative bacteria sensitive to antimicrobial agents are isolated from outpatients is reported. The data were obtained by the standardized Bauer/Kirby technique. Most of the strains examined proved to be sensitive to various betalactam antibiotics, to the tetracyclines, chloramphenicol and sulphamethoxazole/trimethoprim. Aminocyclitols were the most potent drugs. No decrease in sensitivity to standard agents was observed from 1975 to 1980 in E. coli and S. aureus, the most frequently isolated organisms.
