The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases

Journal of Periodontal Research, EarlyView.
This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...

Investigation of the source of haemolytic Escherichia coli infecting weaned pigs [PDF]

, 1987
Attempts were made to discover the source of strains of haemolytic Escherichia coli infecting weaned pigs on a piggery. The organisms were not detected in the faeces of sows in the farrowing house, or in the in the faeces or intestinal tracts of ...

Periodontitis and Inflammatory Bowel Diseases: Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This review aims to provide a conceptual framework for understanding the mechanistic interplay between periodontitis and IBD, with a particular emphasis on the microbial and immunological crosstalk linking the oral cavity and the gastrointestinal tract.

FimH and Anti-Adhesive Therapeutics: A Disarming Strategy Against Uropathogens

Antibiotics, 2020
Chaperone-usher fimbrial adhesins are powerful weapons against the uropathogens that allow the establishment of urinary tract infections (UTIs). As the antibiotic therapeutic strategy has become less effective in the treatment of uropathogen-related UTIs,

A multi-epitope fusion antigen candidate vaccine for Enterotoxigenic Escherichia coli is protective against strain B7A colonization in a rabbit model.

PLoS Neglected Tropical Diseases, 2022
Enterotoxigenic Escherichia coli (ETEC) strains are a leading cause of children's and travelers' diarrhea. Developing effective vaccines against this heterologous group has proven difficult due to the varied nature of toxins and adhesins that determine ...

Fimbrial Adhesins Produced by Atypical Enteropathogenic Escherichia coli Strains [PDF]

Applied and Environmental Microbiology, 2011
ABSTRACT Atypical enteropathogenic Escherichia coli (aEPEC) has emerged as a significant cause of pediatric diarrhea worldwide; however, information regarding its adherence mechanisms to the human gut mucosa is lacking. In this study, we investigated the prevalence of several ( fimA

Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways

Journal of Periodontal Research, EarlyView.
This narrative review aims to provide a comprehensive update on the potential mechanisms by which poor oral health and periodontitis impact lung health, focusing on pneumonia, COPD, and asthma. ABSTRACT Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID‐19, and asthma.

Escherichia coli σ70 senses sequence and conformation of the promoter spacer region [PDF]

, 2010
In bacteria, promoter identification by RNA polymerase is mediated by a dissociable p factor. The housekeeping σ70 factor of Escherichia coli recognizes two well characterized DNA sequence elements, known as the ‘-10’ and ‘-35’ hexamers.

Comparative Genomic Analysis of Multidrug‐Resistant Escherichia coli Across Poultry–Human–Environmental Interfaces

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Whole‐genome sequencing analysis of Escherichia coli isolates from broiler, layer and sonali chickens in Bangladesh shown extensive antimicrobial resistance, diverse virulence factors, plasmid‐mediated resistance, and a highly open pangenome. Comparative genomic analyses demonstrated close genetic relationships with global strains, highlighting the One
