[Revaluation of gentamicin in laboratory and clinical studies (author's transl)]

The MIC of gentamicin and other antibiotics against clinical isolates was determined, and the following sensitivity distribution was obtained. a) Against 54 strains of Staphylococcus aureus, GM had the lowest MIC, followed by TOB, DKB, BB-K8 in order. The distribution range of 0.1-6.25 mug/ml was noted with GM. The peak of MIC was 1.56 mug/ml. b) Against 54 strains of E. coli, the lowest MIC was obtained with GM, and 53 strains (98%) were in the range of 0.4-6.25 mug/ml. The peak of MIC was 3.12 mug/ml. GM was followed by TOB, CL, DKB in order of superiority. c) Against 27 strains of Klebsiella pneumoniae, GM and TOB had the lowest MIC, showing the peak of MIC of 0.8 mug/ml. No significance difference was noted between GM and TOB. GM and TOB were followed by DKB, CL, BB-K8 in order of superiority. d) Against 27 strains of Proteus, GM had the lowest MIC, followed by TOB, DKB and BB-K8 in order. But the peak was 6.25 mug/ml even in GM. The activity of antibiotics against Klebsiella pneumoniae was generally low. e) Against 54 strains of Pseudomonas, the peak of MIC of GM was 3.12 mug/ml and 49 strains (91%) were in the range of 1.56-12.5 mug/ml. Whereas TOB had the peak value of 0.8 mug/ml and 49 strains (91%) were in the range of 0.4-3.12 mug/ml. TOB was followed by DKB, GM, BB-K8 in order of superiority.
