CAMP-test_Streptococcus agalactiae

  • General

    • Streptococcus agalactiae is CAMP-test positive.

      The test is carried out by streaking a beta-hemolysis producing Staphylococcus aureus (ATCC 25923) strain and Streptococcus agalactiae parallel to each other on a blood agar plate.
      Suspect cultures are streaked at right angles in between (but not touching) the two streakes.
      Hemolysis by Streptococcus agalactiae is enhanced in the vicinity of S. aureus.

  • History

    • The CAMP factor reaction was first described in 1944 by Christie, Atkins and Munch-Peterson and reverse to the synergistic lysis of erythrocytes by the beta hemolysin of Staphylococcus aureus and the extra cellular CFB protein of Streptococcus agalactiae.
