A possible role of urinary genotoxic Escherichia coli in prostate cancer in Nigerian patients

BMC Research Notes
Objective Infection and inflammation are potential initiating factors for the development and progression of prostate cancer. This study investigated the presence of bacterial genotoxins; colibactin (clb) and cytolethal distending toxin (cdt) in ...

Escherichia albertii in Wild and Domestic Birds

Emerging Infectious Diseases, 2010
Escherichia albertii has been associated with diarrhea in humans but not with disease or infection in animals. However, in December 2004, E. albertii was found, by biochemical and genetic methods, to be the probable cause of death for redpoll finches ...

Horizontal Transfer of Bacterial Cytolethal Distending Toxin B Genes to Insects. [PDF]

Mol Biol Evol, 2019
Horizontal gene transfer events have played a major role in the evolution of microbial species, but their importance in animals is less clear. Here, we report horizontal gene transfer of cytolethal distending toxin B (cdtB), prokaryotic genes encoding ...

Aging and periodontitis increase brain dissemination of oral bacteria

Journal of Periodontology, EarlyView.
Abstract Background The microbiome is a dynamic system that changes throughout life. Studies have revealed the relationship between periodontal disease and the oral microbiota; however, the impact of periodontal disease on the expression of senescence markers and on the inflammaging of the oral and systemic microbiome remains unclear.

Characterisation of cytolethal distending toxin (CDT) mutants of Campylobacter jejuni [PDF]

Journal of Medical Microbiology, 2000
In order to assess the contribution of cytolethal distending toxin (CDT) to the toxigenicity and pathogenicity of Campylobacter jejuni, the C. jejuni 81-176 and C. jejuni NCTC 11168 CDTs were inactivated by insertional mutation of the cdtB toxin subunit. Cell-free sonicates from isogenic C.

Localized Periodontitis in Young Individuals: Aggregatibacter JP2 Clone, Immunological Dysfunctions and Other Stories

Journal of Periodontal Research, EarlyView.
This review describes the features of grade C molar‐incisor pattern periodontitis and discusses the role of A. actinomycetemcomitans in its pathogenesis and why molars and incisors are preferably affected. Possible future studies on this aggressive disease in primary and permanent dentition and emerging omics techniques for diagnosis and management are

Escherichia coli cytolethal distending toxin blocks the HeLa cell cycle at the G2/M transition by preventing cdc2 protein kinase dephosphorylation and activation [PDF]

, 1997
Cytolethal distending toxins (CDT) constitute an emerging heterogeneous family of bacterial toxins whose common biological property is to inhibit the proliferation of cells in culture by blocking their cycle at G2/M phase.

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

Journal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

Clinical Management of Helicobacter Infection in Captive Baboons (Papio anubis and Papio hamadryas), and Isolation and Molecular Characterization of Three Novel Helicobacter Species

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Background Helicobacter spp. are gastric or enterohepatic bacteria that can be commensal, opportunistic, or pathogenic. Few studies have evaluated Helicobacter spp. in baboons. Methods Twenty‐seven captive baboons were surveyed for Helicobacter spp. by fecal PCR, and a subset evaluated by culture.
