Antibiotic Resistance Flashcards
How do bacteria become resistant?
Bacteria reproduces through variation rapidly and have short generations which allows it to adapt well to that environment. Thus, due to high variations in the gene pool, some bacteria may be resistant to antibiotics once administered. These resistant bacteria will then survive and reproduce and pass on this gene (theory of natural selection). Eventually, a new strain of resistant bacteria will be formed.
What are the problems relating to antibiotic resistance?
Pathogens which were once easily cured, have now turned resistant to first-line antibiotics e.g. tuberculosis. Thus, effects are more severe and lasts longer –> increases the chance of passing it down.
What is another problem of antibiotic resistance?
Due to antibiotic resistance of the first-line, 2nd and 3rd line antibiotics must be used, but it up to 100x more expensive & toxic that 1st line.
What is an example of antibiotic resistance?
Golden staph - a recently discovered “super bug”, which is resistant to almost all antibiotics.
What can golden staph only be killed by?
New experiment drugs.
Where is golden staph usually found?
Hospitals.
Why is golden staph deadly?
As weak and vulnerable people such as elderly and the sick are susceptible.
