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

摘要

The present invention is related with the Microbiology in particular with a selective culture medium for the isolation and detection of species of Streptococcus genus. The proposed medium allows the identification of species of Streptococcus by the appearance of three different tonalities in the organisms to detect and the appearance of fluorescent emissions, besides changes of the coloration of the medium that offers the identification with a high degree of sensibility and specificity.;The medium includes specific ratios of mixtures of nutritive bases, rich in compounds of protein origin (polypeptides, peptides, proteoses, and aminoacids) and vitamins, which facilitate an abundant growth of the target species. In addition, the inclusion of the blood enzymatic hydrolyzate, guarantees the presence in the medium of blood-derived substances or of its fractions that are necessary for the Streptococcus growth, without interfering the identification.
