ABSTRACT:
The invention concerns a medium for specific detection ofStaphylococcus aureusand/or discrimination between positive-coagulaseStaphylococcusand negative-coagulase enablingStaphylococcusto isolate bacteria of the genus staphylococcus and identify theStaphylococcus aureusspecies, which use at least an enzymatic substrate, preferably a chromogenic or fluorescent agent, and still more preferably consisting of an indoxyl or naphthol base. The invention also concerns a method for identifying, and optionally counting,Staphylococcus aureususing such a medium. It consists of aStaphylococcus aureusculture medium and at least an enzymatic substrate enabling testing of an α-glucosidase activity. The invention is particularly applicable in the field of diagnosis.
