specific detection media and identifying and/or counting method using same

Staphylococcus aureus Staphylococcus Staphylococcus Staphylococcus aureus Staphylococcus aureus Staphylococcus aureus The invention concerns a medium for specific detection of and/or discrimination between positive-coagulase and negative-coagulase enabling to isolate bacteria of the genus staphylococcus and identify the species, 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, using such a medium. It consists of a culture medium and at least an enzymatic substrate enabling testing of an α-glucosidase activity. The invention is particularly applicable in the field of diagnosis.
