Study Notes
Antibiotic Resistance and Mechanisms of Action
- A 12-year-old boy acquired a ceftriaxone-resistant Salmonella strain from cattle treated with the drug
- Antibiotics are metabolic products of microorganisms that inhibit or kill other microorganisms
- Mechanisms of action for antibiotics include cell wall active agents, inhibition of nucleic acid synthesis, and inhibition of protein synthesis
- Antibiotic resistance is inevitable due to bio-evolution, and can be acquired through mutations on the chromosome or plasmid
- Plasmid-mediated antibiotic resistance can lead to high-level resistance and is easily transferable to other species
- Acquired antibiotic resistance can occur through mutation, transformation/transposition, or conjugation
- Mechanisms of antibacterial resistance include producing enzymes to inactivate or destroy the drug, altering the drug's target, and preventing entry or efflux of the drug from the cell
- Antibiotic misuse creates a favorable environment for antibiotic-resistant organisms to thrive
- One-third of antibiotic prescriptions are unnecessary, contributing to antibiotic resistance
- Control of antibiotic resistance involves prescription restrictions, rotation, reducing animal use, expertise, surveillance, infection control, and immunization
- Immunization is crucial in preventing human and animal infections, involving vaccines such as live, killed, toxoid, and subunit vaccines
- Vaccines induce immunity to prevent infectious diseases and can be administered through vaccination, including live, killed, toxoid, and subunit vaccines
