Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Addressing controversy in Fusobacterium nomenclature: what exactly does “F. nucleatum” refer to?

Gut Microbes
The F. nucleatum group (sensu lato) is historically composed of four subspecies (F. nucleatum subsp. animalis, F. nucleatum subsp. nucleatum, F. nucleatum subsp. polymorphum, F. nucleatum subsp. vincentii). Although F.

Outer Membrane Vesicles Derived From Fusobacterium nucleatum Trigger Periodontitis Through Host Overimmunity

Advancement of science
The virulent bacteria‐induced host immune response dominates the occurrence and progression of periodontal diseases because of the roles of individual virulence factors from these pathogens in the initiation and spread of inflammation.

Mobile Genetic Elements of Fusobacterium nucleatum

Plasmid, 1995
The gram-negative anaerobic bacterium, Fusobacterium nucleatum, is a predominant member of the human oral flora. As a major component of subgingival plaque, this bacterium has a significant impact on the ecology of the oral cavity due to its ability to adhere to many different microbial species.

Proposal of Three Subspecies of Fusobacterium nucleatum Knorr 1922: Fusobacterium nucleatum subsp. nucleatum subsp. nov., comb. nov.; Fusobacterium nucleatum subsp. polymorphum subsp. nov., nom. rev., comb. nov.; and Fusobacterium nucleatum subsp. vincentii subsp. nov., nom. rev., comb. nov. [PDF]

International Journal of Systematic Bacteriology, 1990
Heterogeneity among isolates of Fusobacterium nucleatum has been recognized for many years. The phenotypic properties of 340 strains considered to be F. nucleatum were examined. While these strains were phenotypically similar and fit the description of F. nucleatum, they could be differentiated into three groups on the basis of electrophoretic patterns

Intraosseous sarcoidosis imitating peri‐implantitis: A case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Sarcoidosis is a multisystem granulomatous disorder of unknown cause, typically affecting the lungs and lymph nodes, but it can also involve the eyes, skin, heart, bones, and other organs. The exact cause is unclear, but genetic factors and environmental triggers like infections, chemicals, or dust may play a role.

Intratumoral presence of the genotoxic gut bacteria pks+ E. coli, Enterotoxigenic Bacteroides fragilis, and Fusobacterium nucleatum and their association with clinicopathological and molecular features of colorectal cancer

British Journal of Cancer
This study aimed to investigate clinicopathological and molecular tumour features associated with intratumoral pks+Escherichia coli (pks+E.coli+), pks+E.coli- (non-E.coli bacteria harbouring the pks island), Enterotoxigenic Bacteroides fragilis (ETBF ...

Site specific endonuclease from Fusobacterium nucleatum

Nucleic Acids Research, 1979
Four different isolates of Fusobacterium nucleatum (A,C,D and E) contain restriction endonucleases of differing specificity. Whilst many of the endonucleases are isochizomers of known enzymes, two novel activities are Fnu DII which recognizes and cleaves the sequence 5'-CGCT-3'/3'-GCGC-5' AND Fnu EI which recognizes and cleaves the sequence 5'-GATC-3 ...

Periodontitis treatment and microbiome in a patient with FAM20A mutation: Case study of 1.5 years

Clinical Advances in Periodontics, EarlyView.
Abstract Background Enamel‐renal‐gingival syndrome (ERGS) is an autosomal recessive disorder caused by mutations in the FAMily with sequence similarity 20A (FAM20A) gene, and is characterized by amelogenesis imperfecta, delayed or failed tooth eruption, and periodontitis.

The role of Fusobacterium nucleatum in colorectal cancer: from carcinogenesis to clinical management

Chronic Diseases and Translational Medicine, 2019
Colorectal cancer (CRC) is a common malignant tumor that affects people worldwide. Metagenomic analyses have shown an enrichment of Fusobacterium nucleatum (F. nucleatum) in colorectal carcinoma tissue; many studies have indicated that F.
