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
