ABSTRACT:
The invention relates to a novel solid medium for detecting meticillin-resistant micro-organisms, containing an antibiotic selected from the cephalosporin group, particularly second and third generation, and a chromogenic agent bearing a chromophore which is released after hydrolysis with an active enzyme in said micro-organisms.
