Green tea catechins inhibit Porphyromonas gulae LPS-induced inflammatory responses in human gingival epithelial cells

Journal of Oral Biosciences, 2022
To determine the anti-inflammatory effects of green tea catechins in immortalized human gingival epithelial cells (Ca9-22) stimulated with Porphyromonas gulae lipopolysaccharide (LPS).Ca9-22 cells were incubated with P. gulae LPS (10 μg/ml) with or without green tea catechins, epigallocatechin-3-gallate (EGCg), epigallocatechin (EGC), epicatechin-3 ...

The Effect of Subacute Oral Folic Acid Treatment on Growth of Porphyromonas gulae in Dogs

Journal of Veterinary Dentistry, 2023
Periodontitis is one of the most prevalent infectious diseases in humans and animals. It is a multifactorial disease resulting in attachment loss and tooth loss. Therefore, preventive dentistry, such as daily teeth cleaning or providing dental chews from puppyhood is essential. This study aimed to find an alternative option for preventive dentistry by

Identification and molecular characterization of Porphyromonas gulae fimA types among cat isolates

Veterinary Microbiology, 2019
Porphyromonas gulae, a Gram-negative black-pigmented anaerobe, is one of several major periodontal pathogens of animals. P. gulae isolates from dogs have been classified into three genotypes based on a 41-kDa filamentous appendage (FimA) on the cell surface, which is closely related to virulence in periodontal disease. However, other specific bacterial

Detection of Porphyromonas gulae from subgingival biofilms of dogs with and without periodontitis

Anaerobe, 2011
A rapid PCR approach was developed to detect Porphyromonas gulae strains from subgingival samples of dogs with and with periodontitis. The presence of P. gulae was observed in 92% and 56%, respectively, in dogs with and without periodontitis. The new primer pair was specific to detect this microorganism, and this technique could be used to evaluate a ...

Role of fimbriae variations in Porphyromonas gulae biofilm formation

Journal of Oral Biosciences
Porphyromonas gulae is a major causative agent of periodontal disease in companion animals that possesses various virulence factors, including fimbriae, lipopolysaccharides, and proteases. P. gulae fimbriae are classified into three genotypes (A, B, and C) based on their nucleotide sequences.

Short communication: Distribution of Porphyromonas gulae fimA genotypes in oral specimens from dogs with mitral regurgitation

Research in Veterinary Science, 2015
Porphyromonas gulae, a suspected pathogen for periodontal disease in dogs, possesses approximately 41-kDa fimbriae (FimA) that are encoded by the fimA gene. In the present study, the association of fimA genotypes with mitral regurgitation (MR) was investigated.
