Porphyromonas gingivalis - Wikipedia
Porphyromonas gingivalis belongs to the phylum Bacteroidota and is a nonmotile, Gram-negative, rod-shaped, anaerobic, pathogenic bacterium. It forms black colonies on blood agar. It is found in the oral cavity, where it is implicated in periodontal disease, [1] as well as in the upper gastrointestinal tract, the respiratory tract, and the colon.
Porphyromonas gingivalis : An Overview of Periodontopathic ...
While human subgingival plaque harbors more than 500 bacterial species, considerable research has shown that Porphyromonas gingivalis, a Gram-negative anaerobic bacterium, is the major etiologic agent which contributes to chronic periodontitis.
Roles of Porphyromonas gingivalis and its Virulence factors ...
P. gingivalis virulence factors subvert immune responses to evade bacterial clearance and promote inflammation. P. gingivalis gingipains degrade C3, C4, and C5 to block complement cascade. Besides, anaphylatoxins C3a, C4a, and C5a are generated to promote inflammation.
Porphyromonas gingivalis : Major Periodontopathic Pathogen ...
Porphyromonas gingivalis is a Gram-negative oral anaerobe that is involved in the pathogenesis of periodontitis, an inflammatory disease that destroys the tissues supporting the tooth which eventually may lead to tooth loss.
Porphyromonas gingivalis - an overview | ScienceDirect Topics
Porphyromonas gingivalis (P. gingivalis) is a major oral pathogen and associated with periodontal diseases including periodontitis and alveolar bone loss. In this review, we indicate that two virulence factors, which are hemoglobin receptor protein (HbR) and cysteine proteases “gingipains”, expressed by P. gingivalis have novel functions on ...
P. Gingivalis - an overview | ScienceDirect Topics
P. gingivalis is an obligately anaerobic, Gram-negative, nonmotile, asaccharolytic, coccobacillus belonging to the phylum Bacteroidetes, which is strongly associated with periodontitis, and can be found in the upper gastrointestinal tract, respiratory tract, and colon.
