Page 4,5,6 - Antimicrobial Resistance (AMR) Flashcards
Countries most vulnerable to climate change and rising temperature showed rising levels of
AMR pathogens
2 methods of bacteria develop AMR
- DNA Mutations
- Acquiring mobile genetic elements from other microorganisms
DNA mutations occur randomly however antimicrobial treatment at sub-therapeutic levels can trigger genome-wide
hypermutations
Subtherapeutic antimicrobial use also places _ _ on microbial populations
selection pressure
A common mechanism of AMR involves DNA mutations within genes coding enzymes that use _, they can also modify _ targets, and proteins affecting _ _
antimicrobials, protein, membrane permeability
Mobile Genetic Elements can be transferred from one organism to another by _ or _ or _
Transformation, Transduction, Conjugation
Transformation is when foreign DNA containing _ gene is incorporated into the genome by _
AMR, recombination
Transduction is when _ (virus that infects bacterium) found in wastewater transfer DNA containing AMR gene between _
bacteriophages, bacteria
Conjugation is when a bacterial _ containing AMR gene is transferred across _ _ that can form between _
plasmid, membrane channel, bacteria
Antimicrobial Misuse occurs when the wrong _ is used, wrong _ is used, _ antimicrobials are used, poor / antimicrobials are used, _ _ isn’t followed, inappropriate _ methods
antibiotic, dosage, banned, quality, expired, treatment period, disposal
_ is when antimicrobials are administered to livestock to prevent disease instead of treating
Overuse
Largest Drivers of AMR
Human and Animal overuse
Other drivers of AMR
Heavy Metals, Biocides, N fertilizers
Reversing AMR by _ use of antimicrobials, the rational behind this is that it may lower _ _, allowing _ that are not AMR to dominate
limiting, selection pressure, microbes
In concern to AGPs and prolonging the use of Therapeutic Antimicrobials what should be done
Ban AGPs
