[Comparative study of bacterial sensitivity to antibiotics with the "abac" automatic system and the agar diffusion disk method].

654 bacterial strains isolated from different biological materials have been tested either with "abac" automatic system or diffusion system on disks according to the Bauer-Kirby standardized method. The higher discrepancy has been observed to Co-trimoxazol antibiotic. Some other discrepancies, non significative, are shown in figures. The use of "abac" provides increased efficiency and convenience improving the quality of routine antimicrobic susceptibility results.
