Streptococcus Selective Agar

Streptococcus Selective Agar

Roantree et al introduced a medium for isolation of group A beta-hemolytic streptococci. The medium-enriched with yeast nucleic acid and maltose promoted increased colony size and enhanced clarity and sharpness of hemolytic zones produced by these organisms. Streptococcus Selective Agar … Read more
