MICROBIOLOGY

  • Anaerobic Gram-positive cocci: part of normal flora of the mouth, GI and GU tracts as well as skin.
  • Heterogeneous group of "anaerobic strep" now classified in 5 groups and changes in taxonomy can be confusing. For example, Finegoldia magna is the former Peptosteptococcus magnus.
  • Small cocci, may be seen on Gram stain in short chains and pairs.
    • GPC seen may appear identical to aerobic streptococci (chains) or staphylococci (clusters) [Fig].
    • Non-spore forming
  • Peptostreptococcus (which includes the former Peptococcus) account for nearly all anaerobic GPC except Finegoldia magna.
  • Most common and important: Finegoldia magna, P. asaccharolyticus. Less common: P. micros, P. anaerobius.
