Microbiology

  • Catalase-negative]] Gram [[Catalase::positive"Gram [[Catalase::positive" is not in the list (Gram-positive, Gram-negative, acid-fast, partially acid-fast, Gram-variable) of allowed values for the "Stain" property. coccus in pairs or chains
  • Two orthogonal classifications
    • Hemolytic properties
      • Alpha: incomplete hemolysis (appears green)
      • Beta: complete hemolysis (appears clear)
      • Gamma: no hemolysis
    • Lancefield antigen group (A-H)
