Document Summary
Lec 7- the global threat of antimicrobial resistance (a complex global public health challenge) Resistance of a microorganism (infectious agent) to an antimicrobial drug that was originally effective: standard treatments become ineffective and infections persist, increasing the risk of spread to others . Overtime, bacteria can become resistant to the antibiotics that one killed them. Require diff antibiotics b/c they have diff cell walls. Essential tools for human and veterinary medicine. Treating infectious diseases and relief of suffering. Preventing the spread of diseases during outbreaks. Prophylactic (preventive) treatment for people at risk for infection. Treating specific infections to reduce the likelihood of infected animals entering human food. Antibiotics attack bacterial or fungal processes of growth and reproduction. Cell wall and membrane (e. g. peptidoglycan cross-linking) Antibiotics aim to interfere with cellular functions, which viruses lack. Antibiotic resistance is a major contributor to the disease, death, and costs resulting from hospital-acquired infections.
