Prevotella intermedia Aggravates Subclinical Hypothyroidism

Journal of Dental Research, 2023
Subclinical hypothyroidism (SCH) has been shown to be associated with microbiota. However, the association between SCH and oral microbiota has not yet been elucidated. The results of our previous clinical studies showed that Prevotella intermedia was abundant in the oral microbiota of SCH patients.

Prevotella intermedia ATCC 25611 Targets Host Cell Lamellipodia in Epithelial Cell Adhesion and Invasion

Oral Microbiology and Immunology, 2009
Introduction: The Prevotella intermedia group bacteria, namely P. intermedia, Prevotella nigrescens, and Prevotella pallens, are phylogenetically closely related and potentially connected with oral and gastrointestinal tract disease pathogenesis. The aim

Degradation of human hemoglobin by Prevotella intermedia

Anaerobe, 2006
In this study, the ability of Prevotella intermedia, an obligate anaerobic rod, to degrade human hemoglobin was determined by SDS-PAGE and the degradation was quantified by scanning densitometry. Both bacterial cells and culture supernatants degraded hemoglobin. The hemoglobin degradation by P.

Glucose metabolism by Prevotella intermedia and Prevotella nigrescens

Oral Microbiology and Immunology, 2000
Glucose metabolism by Prevotella intermedia and Prevotella nigrescens were investigated. Glucose increased the anaerobic growth of these bacteria and promoted the accumulation of intracellular polysaccharide. The polysaccharide was confirmed to be glycogen‐like glucan by the absorption spectrum of iodine‐polysaccharide complex and the sugar composition.

Optimized oligonucleotides for the differentiation of Prevotella intermedia and Prevotella nigrescens

Oral Microbiology and Immunology, 1997
The gram‐negative, anaerobic bacterium Prevotella intermedia plays an important role in the progression of periodontitis, whereas the etiological role of the closely related but phenotypically indistinguishable species Prevotella nigrescens is controversial.

Prevotella intermedia fimbriae mediate hemagglutination

Oral Microbiology and Immunology, 1996
Our earlier studies demonstrated that clinical strains of Prevotella intermedia, isolated from human periodontal pockets, possess various types of fimbria (surface appendages) as determined ultrastructurally. These bacteria have the ability to agglutinate selected mammalian erythrocytes.

Pyogenic vertebral osteomyelitis caused by Prevotella intermedia

Journal of Infection and Chemotherapy, 2002
We describe a case of vertebral osteomyelitis caused by Prevotella intermedia, which is an extremely unusual cause of vertebral osteomyelitis. The organism was isolated from vertebral biopsies and the patient was treated successfully with intravenous ampicillin-sulbactam and clindamycin. Diagnosis and management of this condition are described, and the

Identification of hemolytic activity in Prevotella intermedia

Oral Microbiology and Immunology, 1998
Hemolysin production was measured in strains of Prevotella intermedia. Zones of beta‐hemolysis were detected on agar plates supplemented with either sheep, rabbit or human erythrocytes. A standard tube assay was performed on cell suspensions of the organism to measure hemolytic activity, which was found to be dose dependent, eliminated by heat ...

Occurrence of Prevotella intermedia and Prevotella nigrescens in relation to gingivitis and gingival health

Journal of Clinical Periodontology, 2001
AbstractAim: The occurrence of Prevotella intermedia (Pi) and Prevotella nigrescens (Pn) in relation to natural gingivitis, gingival health and 14‐day experimental gingivitis was investigated in 25 non‐dental students.Materials and Methods:Samples were taken from the dorsum of the tongue, the tonsils (or tonsillar area), and the supra‐ and subgingival ...
