Search for <i>Mycobacterium paratuberculosis</i> DNA in orofacial granulomatosis and oral Crohn’s disease tissue by polymerase chain reaction

Abstract

These results suggest that M paratuberculosis may not be a major aetiological agent in OFG or oral Crohn's disease lesions, although the use of paraffin wax embedded tissue as opposed to fresh tissue as a sample source could underestimate the true prevalence of the organism.
