Study of Antibodies to Cytolethal Distending Toxin B (CdtB) and Antibodies to Vinculin in Patients with Irritable Bowel Syndrome

Association of cytolethal distending toxin locus cdtB with enteropathogenic Escherichia coli isolated from patients with acute diarrhea in Calcutta, India.

Among Escherichia coli strains isolated from stool specimens from patients with acute diarrhea, 1.4% were found to harbor cdtB by use of enrichment cytolethal distending toxin (CDT) PCR. These isolates were identified as being enteropathogenic E. coli (EPEC). In a retrospective study using a probe hybridization assay, 6 of 138 EPEC strains were found to harbor the cdtB locus. cdtB-positive isol...

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...

Auto-antibodies in Patients with Inflammatory Bowel Disease Unclassified

Background: Inflammatory bowel disease unclassified (IBDU) is considered to be an aberrant immune response with loss of tolerance to many antigens. Objective: This paper tries to address whether there is any value to test for auto-antibodies in such patients. Methods: 60 patients with inflammatory bowel disease unclassified participated in the study. Auto-antibodies to nuclear antigen, intestin...
