Research suggests that Clostridium difficile (C.diff) may be evolving to spread in hospitals, according to an article on the Daily Mail website.
Scientists have discovered the bacteria is gradually splitting into two species. The new bug spreads easily, is immune to disinfectants and thrives on the Western diet of sugary foods, they found.
The researchers hope understanding how C.diff adapts to changes in human lifestyles will lead to better infection control.
Outbreaks are thought to occur due to staff easily spreading the bacteria if their hands are contaminated.
