Exposure to foodborne and orofecal microbes versus airborne viruses in relation to atopy and allergic asthma: epidemiological study.

The authors propose that the incidence of allergic disease is inversely correlated with intestinal infection. To test the hypothesis, they carried out a controlled study in young Italian male cadets, comparing 240 atopic cases with 240 non-atopic controls. In another larger study of 1659 cadets, the lifetime cumulative exposure to three intestinal pathogens was estimated and it was found that the greater the exposure, the less chance of developing allergic disease. From these 2 studies, the authors concluded that respiratory allergy is less frequent in persons who have more microbes stimulating the gut. British Medical Journal 2000;320:412-417.
