The Cytolethal Distending Toxin Effects on Mammalian Cells: A DNA Damage Perspective
The cytolethal distending toxin (CDT) is produced by many pathogenic Gram-negative bacteria and is considered as a virulence factor. In human cells, CDT exposure leads to a unique cytotoxicity associated with a characteristic cell distension and induces

Prevalence of virulence genes and cytolethal distending toxin production in campylobacter jejuni isolates from diarrheal patients in Bangladesh? [PDF]
From 300 stool samples, 58 Campylobacter strains were isolated by standard microbiological and biochemical methods. Of these, 40 strains were identified as Campylobacter jejuni and 5 as Campylobacter coli.

Cytolethal distending toxin (CDT) produced by Campylobacter jejuni contains three subunits: CdtA, CdtB, and CdtC. Among these three toxin subunits, CdtB is the toxic moiety of CDT with DNase I activity, resulting in DNA double-strand breaks (DSB) and ...

Cytolethal distending toxin (CDT), a genotoxin produced by Campylobacter jejuni, is composed of three subunits: CdtA, CdtB, and CdtC. CdtB is a DNase that causes DNA double-strand breaks (DSB) in the nucleus resulting in cell cycle arrest at the G2/M ...

Bacterial Genotoxins: Merging the DNA Damage Response into Infection Biology
Bacterial genotoxins are unique among bacterial toxins as their molecular target is DNA. The consequence of intoxication or infection is induction of DNA breaks that, if not properly repaired, results in irreversible cell cycle arrest (senescence) or ...

Alteration of homeostasis in pre-osteoclasts induced by Aggregatibacter actinomycetemcomitans CDT
The dysbiotic microbiota associated with aggressive periodontitis includes Aggregatibacter actinomycetemcomitans, the only oral species known to produce a cytolethal distending toxin (AaCDT). Given that CDT alters the cytokine profile in monocytic cells,

A new functional site W115 in CdtA is critical for Aggregatibacter actinomycetemcomitans cytolethal distending toxin. [PDF]
Aggregatibacter actinomycetemcomitans, a specific pathogen of localized aggressive periodontitis, produces a cytolethal distending toxin (CDT) that arrests eukaryotic cells irreversibly in G0/G1 or G2/M phase of the cell cycle.

Single nucleotide polymorphism in the cytolethal distending toxin B gene confers heterogeneity in the cytotoxicity of A. actinomycetemcomitans [PDF]
Clinical Actinobacillus actinomycetemcomitans produces cytolethal distending toxin (CDT) with titers varying from 102 to 108 U/mg. SNP analysis of the Cdt gene in clinical isolates identified a variation of single amino acid at residue 281 of CdtB, which
