Bacteria recycle broken DNA that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with resistance to antibiotics in hospitals and in our perception of the evolution of life itself. Our surroundings contain large amounts of strongly fragmented and damaged DNA, which is being degraded. Some of it may be thousands of years old. Laboratory experiments with...

Bacterial Transfer Of Resistance Genes Targeted By Scientists
2012-10-24 14:58:18

The bacterium Streptococcus pneumoniae — which can cause pneumonia, meningitis, bacteremia and sepsis — likes to share its antibiotic-defeating weaponry with its neighbors. Individual cells can pass resistance genes to one another through a process called horizontal gene transfer, or by "transformation," the uptake of DNA from the environment. Now researchers report that they can interrupt the cascade of cellular events that allows S. pneumoniae to swap or suck up DNA. The new...
