MEDIUM AND PROCESS FOR THE CULTURE AND SELECTIVE ISOLATION OF THE BACTERIUM ENTEROCOCCUS HIRAE

摘要

The present invention relates to a specific culture medium for the culture and selective isolation of an Enterococcus hirae bacterium, consisting of nutrients other than sugars of a basic culture medium for the culture of enterococci devoid of esculin, comprising inhibitors of Gram-negative bacteria and of Gram-positive bacteria other than enterococci, and preferably at least one antifungal compound, characterized in that it comprises: - as inhibitor of Gram-positive bacteria other than enterococci, sodium chloride at a concentration of at least 20 g/l and no more than 60 g/l; - mannitol as the sole sugar; and - as sole dye, a coloured indicator that changes colour at a pH less than the pH of said specific culture medium, corresponding to the acidification of the specific culture medium resulting from the consumption of the mannitol.
