A few words on Clostridium Difficile.
It has been around for years. It is rare. Contrary to what the media would have you believe, it is not caused by poor hygiene. Just as MRSA lives happily up your nose without causing problems, so C.Difficle lives happily in your colon until the bacteriological environment of the colon is changed. And it is usually changed by an inexperienced junior hospital doctor prescribing a long and inappropriate course of broad spectrum antibiotics. Elderly women frequently get urinary tract infections. Mostly, they can be cured by six tablets of trimethoprim, one twice a day for three days. Cheap, cheerful, narrow spectrum and harmless. But give an inappropriate dose of what inexperienced doctors and nurses tend to view as a “stronger” antibiotic and the balance of the gut flora is disturbed and C.Difficle takes over. (A simple guide to C.Difficile here)
By the way, a quick word on dichotomous naming: as you doctors should know, the second section of the name is not capitalised.
Call me a pedant if you like, but it is Clostridium difficile not Clostridium Difficile...
