Antibiotic resistance.

Cards (5)

    • main causes of antibiotic resistance have been linked to:​
    •Over-prescription of antibiotics.​
    For example, being prescribed antibiotics for the common cold ‘just in case’ The common cold is caused by a virus and antibiotics do not work.​
    •Patients not finishing the entire antibiotic course. For example, stopping a 7 day course on day 5 because they feel better.​
  • What happens when a antibiotic gains resistance
    • The microorganism initially survives exposure to the medication that would normally kill it.​
    • It then mutates, (changes) it’s shape to protect itself from the medication.​
    • These microorganisms then multiply and spread or transfer their resistance to other organisms.
  • Methicillin-resistant staphylococcus Aureus (MRSA)​
    • One of the most well known of the ‘super bugs’​, Resistant to most antibiotics​,Carried on the skin, in the nostrils and throat.​Can cause life threatening infections if they enter wounds​
    • Screening takes place in some situations in hospitals (for example if a wound won’t heal or is infected)​
    • Treatment starts with an antibacterial wash solution.​
    • More recently, some hospitals routinely swab all new admissions.​
    • Also strains of Tuberculosis (TB) , Malaria and more recently, the STD Gonnorrhea that have become resistant to medications.​
  • Mutating viruses​
    • It is not just bacteria that can mutate and become resistant.​
    • Viruses naturally mutate over time .​
    • Once mutated, the immune system no longer recognises it and therefore treats the disease as a new invasion.​
    • Influenza (flu) is one example of this and recently COVID-19.​
  • Consequences of antimicrobial resistance​: Increased mortality rates, increased costs, reduced effectiveness of antibiotics
