Host factors such as age, concurrent gut flora, intrinsic intestinal disease, and other underlying illness also could contribute to induction or resolution of C difficile—associated disease.It seems that the pathogenesis of C difficile enterocolitis in individual cases remains poorly understood. There are reports of spontaneous occurrence
