Summary:
Scientists at Rockefeller University for the first time ever have been able to observe the process of how bacteria adapts to become resistant to antibiotics. By collecting and isolated the bacteria in the blood of a patient with heart disease, the scientists were able to trace how a common strain of bacteria adapted its genes to try to kill it the antibiotics, until it became fully resistant to the antibiotics. This new information may be able to get scientists one step closer to creating an antibiotic that kills the adapted bacteria.
Relevance:
We have recently been learning about the adaptation of species to become better fit for their environment. The bacteria in this article has become resistant to the antibiotics that were once able to kill it. over time the bacteria changes and produces generations that gradually become more and more resistant to the drugs.

Are there any commonly known examples of bacteria that adapt to become resistant to antibiotics?
ReplyDeleteWill they be able to do this with all strains of bacteria and is there anything to stop it from happening again?
