resistant bacteria. Flashcards
define resistant.
unaffected by.
what type of medication kills bacteria?
antibiotics.
what is the causes of variations in bacteria?
mutations in DNA.
define immune.
resistant from.
how would bacteria become resistant to antibiotics?
some bacteria have mutations which make them resistant which then allow them to survive and reproduce and pass on the resistance.
describe the timeline of resistant bacteria development.
mutations of bacterial pathogens produce new strains.
some strains might be resistant to antibiotics and so aren’t killed.
they survive and reproduce, population of the resistant strain rises.
resistant strain spread- people aren’t immune to it and no effective treatment.
how can we slow the rate of anti-bacterial resistance?
doctor shouldn’t over prescribe antibiotics inappropriately such as for non-serious viral infections.
patients should complete their course of antibiotics so all bacteria are killed and non survive to mutate and form resistant strains.
agricultural use of antibiotics should be restricted.
what are the impacts of anti-bacterial resistance?
increased infection rates in hospital.
higher cost to treat infection.
increased length of treatments.
increased side effects from multiple treatments.
vulnerable people at risk: elderly, infants, weak immune systems, illness.
price of meat increases due to treating illness in cattle/ sheep.
