Questions

  1. list the tests that rapidly identify group A streptococcus (Streptococcus pyogenes).
  2. Not all group A streptococd are S. pyogenes. How can the nonpathogenic group A streptococd be differentiated from the pathogenic strains?

Not all S. pyogenes are beta-hemolytic. What is the reason for this phenomenon, and how can the laboratory ensure that it detects the nonhemolytic strains?
