Abstract:
PCR amplification of insertion element IS6110 of Mycobacterium tuberculosis in fecal samples was evaluated in the diagnosis of intestinal tuberculosis (ITB). The numbers of samples that tested positive by PCR with SalI digestion were 16/18 untreated-ITB samples, 0/8 treated-ITB samples, 12/14 smear-positive pulmonary tuberculosis samples, and 0/30 control samples. The sensitivity, specificity, positive predictive value, and negative predictive value of fecal PCR were 88.8%, 100%, 100%, and 93.7%, respectively.
