SELECTIVE CULTURE MEDIUM FOR THE ISOLATION AND/OR DETECTION OF SPECIES IN THE STREPTOCOCCUS GENUS.

摘要

The invention relates to microbiology and, in particular, to a selective culture medium for the isolation and detection of species in the Streptococcus genus. The inventive medium can be used to identify Streptococcus species with the appearance of three different tones in the organisms to be detected and the appearance of fluorescent emissions, in addition to changes in the colour of the medium, thereby providing an identification with a high degree of sensitivity and specificity. According to the invention, the medium comprises specific proportions of mixtures of nutritive bases which are rich in compounds of protein origin (polypeptides, peptides, proteoses, amino acids) and vitamins which favour an abundant growth of the species of interest, as well as the enzymatic hydrolysate of blood, which ensures that substances derived from blood or from the fractions thereof, which are necessary for Streptococcus growth, are present in the medium, without hindering the identification process.
