ABSTRACT:
An incubation limit marker for revealing the growth of contaminants present in a sample includes at least one strain or category of classically contaminant bacteria in dehydrated form which, once regenerated, will be present at a maximum concentration of 10.sup.3 CFU/ml. The incubation limit marker also includes a medium used for the dehydration of the contaminant bacterium or bacteria which includes a substrate capable of being degraded by the bacterium or bacteria. The incubation limit marker further includes an indicator of the growth of the bacterium or bacteria, for example, constituted by a colored indicator of changes in pH. A process for the "in vitro" detection of the susceptibility of pathogenic bacteria to various antibiotics present in MIC (i.e., Minimal Inhibitory Concentration) in culture or antibiogram media is carried out directly from the sample of the infected medium, in the presence of the above marker, used as a signal which limits the reading time of the antibiogram.
