Webbut also binary toxin (CDT). Recent studies indicated that C. difficile strains containing cdt 110gene together with toxin A and toxin B play an important role in the severity of human C. difficile Infection (CDI), with higher recurrent CDI and CDI related fatality rates, compared to the strains with toxin A and B genes only. WebJan 10, 2024 · In addition to the main virulence factors, toxins A and B, these hypervirulent strains produce a third toxin known as C. difficile binary toxin (CDT) or binary toxin. CDT is comprised of CdtA, an actin-specific ADP-ribosyl transferase, and CdtB, the receptor-binding component [ 3 ].

What is a binary toxin compared to the "regular" ones?
WebGenes encoding for toxins A and B are present on the pathogenicity locus (PaLoc). The NAP1/BI/027 strain was discovered in the early 2000s to produce a newly recognized toxin—the binary toxin (4). Although the function of the binary toxin has not been well elucidated, the cdtA and cdtB genes that encode it are located near the PaLoc.
