Volume 1, no. 4, e00512-13, 2013. After publication, we detected the presence of a putative cytolethal distending toxin (CDT) gene cluster in Helicobacter fennelliae MRY12-0050. In the last paragraph before the accession numbers, the third sentence should read as follows: “H. cinaedi and H. hepaticus have been reported to express cytolethal distending toxin (CDT), which causes DNA damage to tar...

Helicobacter hepaticus expresses a member of the cytolethal distending toxin (CDT) family of bacterial cytotoxins. To investigate the role of CDT in the pathogenesis of H. hepaticus, transposon mutagenesis was used to generate a series of isogenic mutants in and around the cdtABC gene cluster. An H. hepaticus transposon mutant with a disrupted cdtABC coding region no longer produced CDT activit...

Cytolethal distending toxins (CDTs) are inhibitory cyclomodulins, which block eukaryotic cell proliferation and are produced by a diverse group of Gram-negative bacteria, including Escherichia coli strains associated with intestinal and extraintestinal infections. However, the mode of transmission of the toxin gene clusters among diverse bacterial pathogens is unclear. We found that Cdt-I produ...

Campylobacter hyointestinalis is considered as an emerging zoonotic pathogen. We have recently identified two types of cytolethal distending toxin (cdt) gene in C. hyointestinalis and designated them as Chcdt-I and Chcdt-II. In this study, we developed a PCR-restriction fragment length polymorphism (RFLP) assay that can differentiate Chcdt-I from Chcdt-II. When the PCR-RFLP assay was applied to...

We have previously shown that Actinobacillus actinomycetemcomitans produces an immunosuppressive factor that is encoded by the cdtB gene, which is homologous to a family of cytolethal distending toxins (Cdt) expressed by several Gram-negative bacteria. Moreover, we have shown that CdtB impairs lymphocyte function by inducing G(2) arrest of the cell cycle. We now report that both CdtB as well as...

Three types of cytolethal distending toxin (CDT), namely, CDT-I, CDT-II, and CDT-III, have been described in Escherichia coli. Using primers designed for the detection of sequences common to the cdtB genes, we analyzed by PCR a set of 21 CDT-producing E. coli strains of intestinal and extraintestinal origins isolated from human and different animal species in several European countries and in t...

Cytolethal distending toxin (CDT) consisting of CdtA, CdtB and CdtC has been reported to be a possible virulence factor of campylobacters including Campylobacter upsaliensis. In our previous study, the cdtB gene-based PCR-restriction fragment length polymorphism (RFLP) assay for detection and differentiation of 7 Campylobacter species yielded 3 different RFLP patterns (Cu-I to Cu-III). In this ...

BACKGROUND Aggregatibacter actinomycetemcomitans (A.actinomycetemcomitans) is an important periodontal pathogen that can participate in periodontitis and other non-oral infections. The cytolethal distending toxin (Cdt) is among the virulence factors produced by this bacterium. This study was to elucidate the distribution of A.actinomycetemcomitans and the prevalence of its cdtB gene in Chinese ...

Aim This study evaluated the frequency of C. difficile and CDAD in the ICU of Shahid Bahonhar Hospital, Kerman, Iran. Background Clostridium difficile (C. difficile) is the most important antibiotic associated diarrhea agent in intensive care unit (ICU) patients. Based on its toxin producing ability, C .difficile is divided to toxigenic and non-toxigenic strains. Methods A total of 233 diar...

Data presented here are associated with the article: "In-depth proteomic analysis of soybean (Glycine max) seeds during controlled deterioration treatment (CDT) reveals a shift in seed metabolism" (Min et al., 2017) [1]. Seed deterioration is one of the major problems, affecting the seed quality, viability, and vigor in a negative manner. Here, we display the gel-based and gel-free proteomic da...
