Infectious diarrhea has many causes, and in the days it takes for current
diagnostic techniques to diagnose the microbe responsible, the infection can
spread quickly and kill. Now scientists from the British Royal Infirmary and
the University of the West of England, both in Bristol, England, have proposed
a novel solution to the problem: a technique that uses gas chromatography
and mass spectroscopy to identify the culprit by analyzing the odor of the
patient's stool (Gut. 2004;53:58-61).
