CausesAppropriate Tests

Bacterial infection

  • Streptococcus pyogenes
  • Streptococcus 'milleri'
  • Bacteroides spp
  • Fusobacterium spp
  • Peptostrptococcus spp

Throat swab, pus - microscopy and culture (pus obtained by needle aspiration or operative drainage).

While some infections are caused by Streptococcus pyogenes alone, many are polymicrobial so culture for anaerobes should be performed.
