A
step forward has been made in understanding how a subset of bacterial cells
escape being killed by many antibiotics. It appears that cells become
"persisters" by entering a state in which they stop replicating and
are able to tolerate antibiotics. Unlike antibiotic resistance, which arises
because of genetic mutations and is passed on to later generations, this
tolerant phase is only temporary, but it may contribute to the later
development of resistance.
For
further details, refer to the following research paper:
