[Critical evaluation of the Abbott MS-2 automatic system in the rapid determination of antibiograms]

The Abbott MS-2 system for rapid determinations of the bacterial growths in the kinetic mode is briefly described. Some details of the operations of the apparatus and about the experimental procedure are given by referring to a phenomenological description for the bacterial growth. A critical analysis of the antimicrobic susceptibilities and of the minimum inhibiting concentrations (MIC) provided by the apparatus is also carried out. In particular the problems arising for cephalosporins is emphasized.
