In another study, Falcone et al. [33] reported that p47phox deficiency increased susceptibility to DSS colitis, while breeding p47phox+/− mice and standardizing the microflora between littermate p47phox−/− and wild‐type mice from birth, significantly reduced DSS and C. rodentium colitis susceptibility in p47phox−/− mice. The gene discussed is NCF1; the disease is colitis.
