Abstract:
Clostridium difficile( C. difficile)is a major nosocomial infection pathogen and the principal causative agent of antibiotic-associated diarrhea. The toxigenic C. difficile strains cause colonic injury and inflammation mainly by secreting enterotoxin A( TcdA)and cytotoxin B( TcdB). The severity of C. difficile associated disease( CDAD)is correlated to the toxin level during host infection. However,the toxigenic capacity of C. difficile varies widely among strains,which correlates with the gene regulation involved during toxin production. This article reviewed the regulatory mechanism of C. difficile toxin-associated pathogenic gene and anti-toxin treatment.
