Multicenter Survey of Routine Determinations of Resistance of Helicobacter pylori to Antimicrobials over the Last 20 Years (1990 to 2009) in Belgium

PCR ribotyping was modified to allow direct detection of Clostridium difficile from stool samples. Direct PCR ribotyping was possible in 86 out of 99 C. difficile-positive stool samples, and in 84 cases (84.8%), the ribotype determined directly from the stool sample was identical to the ribotype of the strain isolated from the same stool sample.
