Clonal Spread of a Clostridium difficile Strain with a Complete Set of Toxin A, Toxin B, and Binary Toxin Genes among Polish Patients with Clostridium difficile-Associated Diarrhea

摘要

Clinically relevant Clostridium difficile strains usually produce toxins A and B. Some C. difficile strains can produce an additional binary toxin. We report clonality among five strains carrying all toxin genes from Polish patients with C. difficile-associated diarrhea. In another strain, possible recombination between binary toxin genes is documented.
