A real-time quantitative PCR assay for evaluating Clostridium difficile adherence to differentiated intestinal Caco-2 cells.

Abstract:

:Herein we describe a real-time quantitative PCR assay for evaluating the adherence of Clostridium difficile to differentiated human intestinal Caco-2 cells. Our investigations demonstrated that the method, employing the C. difficile-specific triose-phosphate isomerase gene, is as reliable but less time-consuming than counting c.f.u. We conclude that the method will be useful for evaluating the role of host cell adherence in the pathogenesis of C. difficile infection.
