MI 1.2.1

Front

This antibiotic works by making it difficult for the bacteria to form cell walls (capsule) correctly. The peptidoglycan can't cross-link, so the walls are weak, and the cells burst. It actually kills bacteria, not inhibits them.

Back

Penicillin (beta-lactam)

Front

This antibiotic works by binding to ribosomes, preventing bacteria from synthesizing proteins and reproducing.

Back

Tetracyclines

Front

This antibiotic works by interfering with bacteria's ability to copy their DNA. This stops them from reproducing.

Back

Fluoriquinolones

Front

This antibiotic works by interfering with a B vitamin (folate) that bacteria require to survive. They can't reproduce or grow well without that vitamin.

Back

Sulfa antibiotics (sulfonamids)
