Submission + - Watching Drug Resistance Develop in Real Time

nursegirl writes: As the spread of multi-drug resistant bacteria like MRSA and the new XDR-TB (extremely drug resistant tuberculosis) becomes a growing concern throughout the world, a team of scientists has been able to learn how bacteria evolves in vivo as a response to vancomycin and other antibiotics.

The team isolated S. aureus bacteria intermittently through a patient's antibiotic therapy and sequenced the genome of the bacterium multiple times. The results demonstrated 35 mutations in 31 locations as the bacteria evolved from vancomycin-susceptible to vancomycin-resistant.

Be careful when a loop exits to the same place from side and bottom.
