3. Antibiotics
Medications used to treat bacterial infections
Ideally, before beginning antibiotic therapy, the suspected areas of
infection should be cultured to identify the causative organism and
potential antibiotic susceptibilities.

4. TYPES
Bactericidal: kill bacteria
Bacteriostatic: inhibit growth
of susceptible bacteria, rather
than killing them
immediately; will eventually
lead to bacterial death

5. Ideal Qualities

7. Ampicillin
First introduced in the 1940s
Bactericidal: inhibit cell wall
synthesis
Kill a wide variety of bacteria

8. Mode of Action
Beta lactum antibiotics (pencillin and ampicillin) act by
inhibition of cell wall formation in bacteria
Disrupt of peptidoglycan synthesis
Inhibiting the action of the enzyme trans peptidase that is
necessary for crosslinking of peptidoglycan, which form the
skeleton of bacterial cell wall

11. Mode of Action
Inhibit microbial protein synthesis
Binds reversibly to the 50S ribosomal subunit of bacteria
Inhibit the peptidyl transferase step of protein synthesis
Prevents the formation of peptide bonds
