Treponema species enrich the gut microbiota of traditional rural populations but are absent from urban individuals

New Microbes and New Infections, 2019
There is a significant gap in our knowledge of the microbe–host relationship between urban and traditional rural populations. We conducted a large-scale study to examine the gut microbiota of different traditional rural and urban lifestyles in human ...

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.

Quantifying and mapping digital dermatitis–associated bacteria in lesion and nonlesion body sites and dairy farm environment

Journal of Dairy Science
: The source of infection of digital dermatitis (DD), an infectious lameness condition, is still uncertain. In this cross-sectional study, we aimed to identify potential reservoirs of DD bacteria in dairy cattle body sites with different stages of the ...

A sero-epidemiological approach to explore transmission of Mycobacterium ulcerans [PDF]

, 2016
The debilitating skin disease Buruli ulcer (BU) is caused by infection with Mycobacterium ulcerans. While various hypotheses on potential reservoirs and vectors of M. ulcerans exist, the mode of transmission has remained unclear.

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 ...

Matrix Metalloproteinases in Periodontal and Peri‐Implant Diseases: Contribution to Their Pathogenesis, Diagnosis, and Treatment

Journal of Periodontal Research, EarlyView.
This graphical abstract illustrates the role of matrix metalloproteinases (MMPs) across the pathogenesis, diagnosis, and therapeutics of periodontal and peri‐implant diseases. Microbial and host stimuli trigger MMP activation leading to extracellular matrix breakdown, point‐of‐care aMMP‐8 detection aids diagnosis, and adjunctive or AI‐assisted ...

Complete genome sequence of Treponema paraluiscuniculi, strain Cuniculi A: the loss of infectivity to humans is associated with genome decay.

PLoS ONE, 2011
Treponema paraluiscuniculi is the causative agent of rabbit venereal spirochetosis. It is not infectious to humans, although its genome structure is very closely related to other pathogenic Treponema species including Treponema pallidum subspecies ...

Methanogenic \u3cem\u3eArchaea\u3c/em\u3e and human periodontal disease [PDF]

, 2004
Archaea have been isolated from the human colon, vagina, and oral cavity, but have not been established as causes of human disease. In this study, we reveal a relationship between the severity of periodontal disease and the relative abundance of archaeal
