Abstract:
:It is difficult to make a precise diagnosis of intestinal tuberculosis and to differentiate it from Crohn's disease. For evaluating Polymerase Chain Reaction (PCR) assay in these two aspects, 36 specimens of intestinal tuberculosis from surgical resections and endoscopic biopsies and 26 Crohn's disease samples were subjected to PCR assay. 21 specimens of normal colon tissue surrounding cancer were used as the control. Oligonucleotides derived from the IS 6110 sequence, which is repeated in M. tuberculosis chromosome and highly specific for the M. tuberculosis complex, were used as a primer. The amplified PCR products were detected by examination of ethidium-bromide-stained polyacrylamide gels. The specificity of PCR products was confirmed by digestion with Sal I restrictive endonuclease and southern blot hybridization using digoxigenin-labeled probe. The results showed that the M. tuberculosis DNA was identified in 27/36 intestinal tuberculosis, but none of 26 Crohn's disease. Acid fast bacilli were only found in 16/36 intestinal tuberculosis. In conclusion, as a rapid, sensitive, and specific pathogenic method in diagnosis of intestinal tuberculosis, PCR assay has been developed in this study, and is considered valuable in the differentiation between intestinal tuberculosis and Crohn's disease.
