Rapid Detection of Clostridium difficile Infection: Performance Evaluation of the GDH + Toxin A + Toxin B Combo Rapid Test Cassette
Author(s): Zhang Lei*, Yang Feng and Hangzhou
Clostridium difficile, an anaerobic bacterium, opportunistically thrives in the intestinal tract when the normal microbiota is disrupted by antibiotic treatment. It acts as a pathogen, capable of causing various infections ranging from mild diarrhea to lifethreatening pseudomembranous colitis. The pathogenicity of this disease is attributed to two toxins: Toxin A, an enterotoxin causing tissue damage, and Toxin B, a cytotoxic. While some strains produce both toxins, others produce only Toxin B. The role of a third toxin, known as the binary toxin, in the pathogenicity of Clostridium difficile is still a subject of debate. The detection of Glutamate Dehydrogenase (GDH), an antigen marker for C. difficile proliferation, has proven to be highly effective as all strains produce this enzyme abundantly.
