Azoreductase and Nitroreductase Activity of Bacteria in Feces from Reservoir Patients with an Ileal

Azoreductase and nitroreductase activities ofbacteria in feces of five patients with ileal reservoirswere evaluated, both at the onset of symptoms ofpouchitis and following recovery after treatment with drugs. All stool samples tested had bacteriawith azoreductase and nitroreductase activities.Azoreductase and nitroreductase activities were higherafter recovery than during attacks of pouchitis. During reestablishment of the normal microflora in theileal reservoirs after pouchitis, the anaerobic bacteriaincreased and the aerobic bacteria decreased.
