Characterization of the cytolethal distending toxin (typhoid toxin) in non-typhoidal Salmonella serovars

BACKGROUND For many putative Salmonella enterica subsp. enterica virulence genes, functional characterization across serovars has been limited. Cytolethal distending toxin B (CdtB) is an incompletely characterized virulence factor that is found not only in Salmonella enterica subsp. enterica serovar Typhi (Salmonella Typhi) and dozens of Gram negative bacterial pathogens, but also in non-typhoi...

Delivery of a Salmonella Typhi exotoxin from a host intracellular compartment.

Salmonella Typhi, an exclusive human pathogen and the cause of typhoid fever, expresses a functional cytolethal distending toxin for which only the active subunit, CdtB, has been identified. Here, we show that PltA and PltB, which are encoded in the same pathogenicity islet as cdtB, associate with CdtB to form a multipartite toxin. PltA and PltB are homologs of components of the pertussis toxin...

The Aggregatibacter actinomycetemcomitans Cytolethal Distending Toxin Active Subunit CdtB Contains a Cholesterol Recognition Sequence Required for Toxin Binding and Subunit Internalization.

Induction of cell cycle arrest in lymphocytes following exposure to the Aggregatibacter actinomycetemcomitans cytolethal distending toxin (Cdt) is dependent upon the integrity of lipid membrane microdomains. Moreover, we have previously demonstrated that the association of Cdt with target cells involves the CdtC subunit which binds to cholesterol via a cholesterol recognition amino acid consens...

CdtA, CdtB, and CdtC form a tripartite complex that is required for cytolethal distending toxin activity.

Campylobacter jejuni encodes a cytolethal distending toxin (CDT) that causes cells to arrest in the G(2)/M transition phase of the cell cycle. Highly related toxins are also produced by other important bacterial pathogens. CDT activity requires the function of three genes: cdtA, cdtB, and cdtC. Recent studies have established that CdtB is the active subunit of CDT, exerting its effect as a nucl...
