[Further investigations into the effectiveness of gentamicin and other antibiotics against urinary tract infection organisms (author's transl)].

In continuance of our investigations from 1968 to 1972, we isolated 32939 microorganisms from urinary tract infections and subjected them to routine sensitivity tests against six antibiotics from 1973 to August 1975. All organisms except enterococci and proteus proved to be sensitive to gentamicin at a level exceeding 90% during the study period of two and a half years. A loss of activity of gentamicin worth mentioning was not detected during the studies. So this antibiotic must further be considered as one of the drugs of first choice in the treatment of urinary tract infections.
