Antibiotic classes and mechanism

These are the different classes of medications and their mechanism of action. I’ve sorted them by which ones are exclusively Gram + or Gram – and which ones do both.

Here’s a handy mnemonic for remembering the antibiotics that act on the ribosomes (I find they’re the most confusing to remember):

Buy AT 30
Aminoglycosides
Tetracyclines

CELL for 50
Clindamycin
Erythromycin
Linezolid

  1. Love your work, Ali!
    looks like you’ve left off Glycopeptides though. They only cover gram positives.
    I try and think of the GP as in Gram Positive Glyco Peptide!

  2. Hello,
    I have a question about the acronyms PABA, DHFA and THFA, could you write what they stand for please ?

    Congratulations for this awesome website :)
