The pathogenesis of colitis due to Clostridium difficile is closely linked to the elaboration of 2 large, single-unit glucosyltransferases referred to as toxin A (TcdA) and toxin B (TcdB). Clinical isolates from patients with symptomatic C. difficile infection (CDI) invariably produce both TcdA and TcdB or TcdB alone. Vaccination of experimental hamsters against both toxins prevents fatal C. di...

The toxins TcdA and TcdB produced by the human pathogen Clostridium difficile gain entrance to host epithelial cells by recognizing cell-surface carbohydrate ligands. Inhibiting the attachment of these toxins to host cells has been proposed to be a viable therapy to treat C. difficile infections. Glycan array screening previously revealed that the Le(A)-LacNAc pentasaccharide binds strongly to ...

Clostridium difficile is a spore-forming, gram-positive, anaerobic bacillus that can cause C. difficile infection (CDI). However, only a few studies on the prevalence and antibiotic resistance of C. difficile in healthy individuals in China have been reported. We employed a spore enrichment culture to screen for C. difficile in the stool samples of 3699 healthy Chinese individuals who were divi...

Clostridium difficile is an important nosocomial pathogen and the leading cause of hospital-acquired diarrhea. Antibiotic use is the primary risk factor for the development of C. difficile-associated disease because it disrupts normally protective gut flora and enables C. difficile to colonize the colon. C. difficile damages host tissue by secreting toxins and disseminates by forming spores. Th...
