Drugs capable of inhibiting/destroying disease-causing bacteria.
Prevent the formation of bacterial cell walls – peptidoglycan – can inhibit synthesis of peptide links that hold molecules together. Cell wall is weakened and osmotic lysis occurs.
OSMOTIC LYSIS: water enters cells by osmosis, pressure builds up if too much water enters, cells burst.
Antibiotics can work by:
· Bind to bacterial ribosomes & inhibit protein synthesis – not dangerous to humans, because bacterial ribosomes & protein synthesis aren’t same as in humans
· Disrupt DNS synthesis during DNA replication
· Disrupt cell membranes
