◦ Animal tolerate Antimicrobial & its side effects such as vomiting/diarrhea, Nephrotoxicity.
Antibiotic Susceptibility
The effectiveness of an antibiotic in inhibiting the growth of the bacteria is reflected in its measurable minimum inhibitory concentration (MIC)
what drug inhibit cell wall formation?
Pencillins & Cephalosporins
What drugs change the permeability of the cell membrane resulting in death of the cell
Antifungals
what drug inhibit protein synthesis preventing the cell from being able to grow and reproduce

What drugs damage bacterial DNA or RNA which prevents prolific action and/or reproduction of the bacteria causing death
Quinolones
