  12. anerobe
    Gram +
    rod
    name me and how to treat!
    • Clostridium difficile
    • PO vancomycin or flagel

    start with metronidazole because is narrow spectrum dont respond in 3-5 days switch to PO vancomycin
  13. Gram -
    Anerobe
    rod
    name me!
    Bacteroides fragilis--

    causes foul smelling ulcers and abcesses
