Poop sniff test

It's a dirty job, but nobody's got to do it any more. Researchers from the University of Leicester, UK, have developed an electronic nose that can sniff out the chemical signs of disease in a feces sample. The system based on mass spectrometry can detect the chemical signature of the potentially deadly microbe Clostridium difficile, which is a serious health concern in hospitals and elsewhere. Writing in the journal Metabolomics, the team explains that the same system might be able to detect different strains. Some forms of C diff cause stomach pain and diarrhea other, but there are strains that can be lethal, particularly in vulnerable patients.
