Why does CDT increase the virulence of C difficile?
CDT production is generally associated with increased virulence of C. difficile, although the mechanism is uncertain; it is cytotoxic in vitro and believed to enhance adherence of C. difficile to the intestinal epithelium 3.
How is C difficile spread from person to person?
C. difficile is spread via the faecal-oral route by ingestion of spores, which are resistant to drying, heat and many disinfectants and so persist in the environment, particularly in the vicinity of individuals with diarrhoea due to C. difficile.
