Prevotella species as oral residents and infectious agents with potential impact on systemic conditions

Journal of Oral Microbiology, 2022
Oral Prevotella are known as anaerobic commensals on oral mucosae and in dental plaques from early life onwards, including pigmented P. melaninogenica, P. nigrescens, and P. pallens and non-pigmented Prevotella species. Many Prevotella species contribute

Adherent-invasive E. coli – induced specific IgA limits pathobiont localization to the epithelial niche in the gut

Frontiers in Microbiology, 2023
Background and aimAdherent-invasive E. coli (AIEC) has been identified as a pathobiont associated with Crohn’s disease (CD), that prefers to grow in inflammatory conditions.

Gastrointestinal Pathobionts in Pediatric Crohn’s Disease Patients [PDF]

International Journal of Microbiology, 2018
Crohn’s disease (CD) is an inflammatory disease of the gastrointestinal tract, with a rising incidence worldwide, particularly in children. CD is thought to arise due to an immune response to environmental factors. The role of bacteria in CD has recently been highlighted, and here, we examine the prevalence of two bacterial species ...

Oral Vaccination Reduces the Effects of Lawsonia intracellularis Challenge on the Swine Small and Large Intestine Microbiome

Frontiers in Veterinary Science, 2021
Porcine proliferative enteropathy remains one of the most prevalent diseases in swine herds worldwide. This disease is caused by Lawsonia intracellularis, an intracellular bacterial pathogen that primarily colonizes the ileum. In this study, we evaluated

Preterm Infants Harbour a Rapidly Changing Mycobiota That Includes Candida Pathobionts

Journal of Fungi, 2020
Fungi and the mycobiome are a fundamental part of the human microbiome that contributes to human health and development. Despite this, relatively little is known about the mycobiome of the preterm infant gut.

Dysbiosis by Eradication of Helicobacter pylori Infection Associated with Follicular Gastropathy and Pangastropathy

Microorganisms, 2023
Dysbiosis plays an important role in the development of bacterial infections in the gastric mucosa, particularly Helicobacter pylori. The international guidelines for the treatment of H.

Sequestration of gut pathobionts in intraluminal casts, a mechanism to avoid dysregulated T cell activation by pathobionts

Proceedings of the National Academy of Sciences, 2022
T cells that express the transcription factor RORγ, regulatory (Treg), or conventional (Th17) are strongly influenced by intestinal symbionts. In a genetic approach to identify mechanisms underlying this influence, we performed a screen for microbial genes implicated, in germfree mice monocolonized with Escherichia coli

The Cynomolgus Macaque Intestinal Mycobiome Is Dominated by the Kazachstania Genus and K. pintolopesii Species

Journal of Fungi, 2022
The cynomolgus macaque, Macaca fascicularis, is a non-human primate (NHP) widely used in biomedical research as its genetics, immunology and physiology are similar to those of humans.

Porphyromonas gingivalis: keeping the pathos out of the biont

Journal of Oral Microbiology, 2013
The primary goal of the human microbiome initiative has been to increase our understanding of the structure and function of our indigenous microbiota and their effects on human health and predisposition to disease.

Die Kämpfe únd schláchten—the struggles and battles of innate-like effector T lymphocytes with microbes

Frontiers in Immunology, 2023
The large majority of lymphocytes belong to the adaptive immune system, which are made up of B2 B cells and the αβ T cells; these are the effectors in an adaptive immune response.
