You work in a clinical lab. A sample you cultivated overnight on blood agar yielded B-hemolytic colonies, suggestive of Streptococcus pyogenes, a member of the lactic acid bacteria. Unlike most bacteria that grow in the presence of O2, lactic acid bacteria are catalase-negative. If a catalase test on a colony yielded a positive result, what would this tell you about the identity of your organism? O This result does not tell you much about your sample. O Your sample is Streptococcus pyogenes. O Your organism may or may not be Streptococcus pyogenes. O Your sample is not Streptococcus pyogenes
