Background: Clostridium difficile is a Grampositive, spore-forming, anaerobic bacterium commonly found in low concentrations in the intestine of clinically normal animals and humans. Pathogenic Clostridium difficile strains produce multiple toxins. The best characterized ones are enterotoxin (Clostridium difficile toxin A) and cytotoxin (Clostridium difficile toxin B), both of which may produce diarrhea and inflammation. Clostridium difficile infection (CDI) is a major cause of nosocomial antibiotic-associated infectious diarrhea and pseudomembranous colitis in humans.

Description: BactoReal® Kit Clostridium difficile uses real-time PCR for the detection of the Clostridium difficile toxin A (tcdA) gene and Clostridium difficile toxin B (tcdB) gene of C. difficile. Our carefully designed primers and probe ensure highest sensitivity and specificity. The kit consists of an assay mix for the detection of the pathogen as well as a positive control and an internal positive control (IPC). To minimize PCR cross-contamination,the reaction mix included contains dUTP and uracil-N glycosylase (UNG). For more detailed information see here.
