[Comparison of three methods of measuring antibiotic sensitivities (author's transl)]

Two semi-automatic methods of measuring antibiotic sensitivities were compared to the disk method for everyday use in a bacteriology laboratory. The reproducibility, compared with 3 strains, proved satisfactory, the highest was the API method. There appeared to be few discrepancies between the semi-automatic methods and the disk method. Part of the latter may be explained by the difference of critical concentrations. Others, routine for a few antibiotics, merit more complete study.
