The Influence of Oral Bacteria on Epithelial Cell Migration In Vitro

open access: yesMediators of Inflammation, 2013
Oral ulcerations often arise as a side effect from chemo- and radiation therapy. In a previous clinical study, Porphyromonas gingivalis was identified as a positive predictor for oral ulcerations after hematopoetic stem cell transplantation, possibly ...

Saliva, supragingival biofilm and root canals can harbor gene associated with resistance to lactamic agents

open access: yesBrazilian Oral Research, 2015
This study aimed to determine the presence of Prevotella strains and genes associated with resistance to lactamics in different oral niches from patients with/without primary endodontic infections. Saliva (S) and supragingival biofilm (SB) were collected

Binding and degradation of lactoferrin byPorphyromonas gingivalis Prevotella intermediaandPrevotella nigrescens [PDF]

open access: yesFEMS Immunology & Medical Microbiology, 1996
The ability of laboratory and clinical strains of Porphyromonas gingivalis, Prevotella intermedia and Prevotella nigrescens to bind and to degrade lactoferrin (Lf) has been assessed. Lf bound readily to whole cells of each species apparently via high-affinity site and one or more low-affinity sites. P. gingivalis showed a lower affinity for Lf than the

Antimicrobial Activity of Diterpenes from Viguiera arenaria against Endodontic Bacteria

open access: yesMolecules, 2011
Six pimarane-type diterpenes isolated from Viguiera arenaria Baker and two semi-synthetic derivatives were evaluated in vitro against a panel of representative microorganisms responsible for dental root canal infections. The microdilution method was used

Role of Porphyromonas gingivalis, Prevotella intermedia, and Prevotella nigrescens in Extraoral and Some Odontogenic Infections [PDF]

open access: yesClinical Infectious Diseases, 1997
Porphyromonas gingivalis, Prevotella intermedia, and Prevotella nigrescens were isolated from 138 subjects with various infections (intraabdominal, skin and soft-tissue, head and neck, pleuropulmonary, and odontogenic infections and bacteremia). The phenotypic identification of 173 isolates was completed by molecular methods.

Endodontic-Like Oral Biofilms as Models for Multispecies Interactions in Endodontic Diseases

open access: yesMicroorganisms, 2020
Oral bacteria possess the ability to form biofilms on solid surfaces. After the penetration of oral bacteria into the pulp, the contact between biofilms and pulp tissue may result in pulpitis, pulp necrosis and/or periapical lesion.

Presence of Porphyromonas and Prevotella species in the oral microflora of cattle with periodontitis

open access: yesPesquisa Veterinária Brasileira, 2015
Abstratc: Bovine periodontitis is a progressive purulent infectious process associated with the presence of strictly and facultative anaerobic subgingival biofilm and epidemiologically related to soil management in large geographic areas of Brazil.
