Clostridium difficile, an anaerobic spore-forming gram-positive bacillus, is the most important cause of antibiotic-associated diarrhea and pseudomembranous colitis. Polymerase chain reaction (PCR) assays have been developed to detect genetic markers in the PaLoc region of C difficile. While it is the most efficient direct method for laboratory diagnosis of C difficile infection, some laboratories may prefer the algorithmic approach using PCR as a confirmatory test for the presence of toxin.
