그람양성, 그람음성 세균 분류, 종류 (catalase, coagulase, oxidase test 등에 따라)

Gram positive(그람양성) : Staphylococci, Streptococci, Enterococci, Bacillus, Corynabacterium, Listeria, Lactobacillus, Actinomyces
Gram negative(그람음성) : Enterobacteriaceae, Pseudomonas, Haemophilus, Brucella, Legionella, Burkholderia cepacia, Vibrio, Acinetobacter, Stenotrophomonas maltophilia, Neisseria

 

Gram positive(그람양성) : G(+)라고 표기

Gram negative(그람음성) : G(-)라고 표기

 

G(+) cocci : Catalase test 시행
  Catalase(+) : Staphylococci임, Coagulase test 시행.
    Coagulase(+) : S.aureus
    Coagulase(-) : 일명 CNS – S.epidermidis
  Catalase(-) : Streptoccci or Enterococci

 

G(+) bacilli : Spore 여부 확인
  Spore(+) : Bacillus spp.
  Spore(-) : Calatase test 시행
    Catalase(+) : Corynebacterium, Listeria
    Catalase(-) : Lactobacillus, Actinomyces

 

G(-) cocci : Thayer Martin agar에서의 growth 확인
  (+) : Pathogenic Neisseria spp.
  (-) : Other Neisseria spp.

G(-) bacilli : MacConkey agar에서의 growth 확인
  (+) : Enterobacteriaceae, Pseudomonas 등임. Oxidase test 시행.
    Oxidase (+) : Pseudomonas, Vibrio, Burkholderia cepacia
    Oxidase (-) : Enterobacteriaceae, Acinetobacter, Stenotrophomonas maltophilia
  (-) : Haemophilus, Brucella, Legionella
