Study Notes
Cephalosporinase and Chloramphenicol Acetyltransferase
- Cephalosporinase is a type of β-lactamase.
- Chloramphenicol acetyltransferase is an enzyme that inactivates chloramphenicol.
Bacteria and Antimicrobials
- Campylobacter jejune is a microphilic bacteria.
- Chloramphenicol acts by inhibiting protein synthesis.
- Antibiotics can inhibit bacterial growth by targeting the cell wall, DNA synthesis, or metabolic pathways.
Antibiotic Mechanisms
- Streptomycin, Clarithromycin, and Tedizold work by binding to the 50S subunit.
- Penicillinase-resistant penicillins include Oxacillin and Dicloxacillin.
- Antistaphylococcal antibiotics include Oxacillin, Dicloxacillin, and Nafcillin.
Antibiotic Sources
- Kanamycin is produced by Streptomyces bacteria.
- Cephalosporins are derived from the fungus Cephalosporium lactamdurans.
Antibiotic Generations
- Cephamycins are a type of antibiotic.
- Cefepime and Ceftazidime are fifth-generation cephalosporins.
- Ceftaroline is a fifth-generation cephalosporin.
