Human Intestinal Spirochetosis Shows Higher Positivity in Sessile Serrated Lesions Than in Tubular Adenomas With Preferential Colonization of Absorptive Epithelium. [PDF]

Pathol Int
Human intestinal spirochetosis (HIS) positivity was significantly higher in sessile serrated lesions (SSLs) than in tubular adenomas (TAs). HIS preferentially colonized absorptive epithelium, which is abundant in SSLs but limited in TAs, indicating that differences in absorptive epithelial abundance account for the higher HIS positivity in SSLs ...

Pathogenicity of porcine intestinal spirochetes in gnotobiotic pigs

, 1994
Twelve intestinal spirochete strains of porcine origin were characterized on the basis of their phenotypic properties, by multilocus enzyme electrophoresis, and by pathogenicity testing in gnotobiotic pigs.

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Human intestinal spirochetes are distinct from Serpulina hyodysenteriae

, 1993
Twenty-nine intestinal spirochetes isolated from Australian aboriginal children and six strains from Italian adults (HRM1, -2, -4, -5, -7, and -14) were genetically examined at 15 enzyme loci by using multilocus enzyme electrophoresis.

The complete genome sequence of the pathogenic intestinal spirochete Brachyspira pilosicoli and comparison with other Brachyspira genomes

, 2010
Background: The anaerobic spirochete Brachyspira pilosicoli colonizes the large intestine of various species of birds and mammals, including humans. It causes ''intestinal spirochetosis'', a condition characterized by mild colitis, diarrhea and reduced ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...
