Porphyromonas

Porphyromonas

(pōr'fir-om'ō-năs),
A genus of small anaerobic gram-negative nonmotile cocci and usually short rods that produce smooth, gray to black pigmented colonies the size of which varies with the species. In humans, they are found as part of the normal flora in the oropharynx, including gingival crevices, and in the vaginal and intestinal tracts. The type species is Porphyromonas asaccharolytica.

Por·phyr·o·mon·as

(pōr-fir-ŏm'ō-năs)
A genus of small, anaerobic, gram-negative, nonmotile, pleomorphic cocci and usually short rods that produce smooth, gray-to-black-pigmented colonies, the size of which varies with the species. In humans, they are found as part of the normal flora in the oropharynx, including gingival crevices, and in the vaginal and intestinal tracts. The type species is P. asaccharolytica.

Porphyromonas

(pōr″ fĭ-rō-mōn′ ăs) [Gr. porphyra, purple + monas, single]
A genus of gram-negative, rod-shaped, anaerobic bacteria that inhabits the oral cavity. One species, Porphyromonas gingivalis, is a common cause of gingivitis and periodontal infection.

Porphyromonas

a genus of gram negative, anaerobic bacteria previously grouped in the genus Bacteroides. Involved in periodontal disease and a cause of dog and cat bite wound infections.

For example, when Porphyromonas gingivalis and Tannerella forsythia are present in the subgingival plaque, a patient is more likely to develop chronic periodontitis, more likely to progress to advanced periodontal disease, and less likely to experience a successful treatment outcome.
The microbiological parameters Aggregatibacter actinomycetemcomitans (Aa), Fusobacterium nucleatum (Fn), Porphyromonas gingivalis (Pg) and Prevotella intermedia (Pi) were recorded.
Microbiological studies have demonstrated Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Fusobacterium nucleatum, and Treponema denticola organisms, suggesting that many pathogens may be involved in the disease process.
The bacterium causing periodontitis, namely Porphyromonas gingivalis, causes citrullination through its own PADI enzyme.
This leaves us vulnerable to infections by bacteria that cause gum disease, such as Porphyromonas gingivalis.
Using culturing-based studies of the bacteria growing at healthy and periodontitis-affected sites, three species have been identified as significantly associated with clinical disease severity: Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia.
Estudios demuestran que las enfermedades periodontales estan asociadas a multiples bacterias, tanto gran-negativas como gran-positivas, pero vienen siendo la Porphyromonas gingivales y Aggregatibacter actinomycetemcomitans las principales responsables del inicio y progreso de esta enfermedad, causando asi la destruccion del tejido directamente a traves de productos patogenos tales como endotoxinas y colagenasas o por provocar una respuesta immune.
Levels of interleukin IL-1[beta], IL-8 and IL-10 in saliva and gingival crevicular fluid (GCF) were evaluated by ELISA, as well as the expression of Porphyromonas gingivalis (Pg), Aggregatibacter actinomycetemcomitans, (Aa) Tannerella forsythia (Tf), and Treponema denticola (Td), by qPCR.
24, 2016 /PRNewswire/ -- Two new research studies demonstrate how the 1064nm wavelength PerioLase[R] MVP-7[TM] dental laser system, optimized for the LANAP[R] protocol, selectively destroys Porphyromonas gingivalis (Pg), a "keystone" pathogen that directs other gum tissue bacteria to become pathogenically active in the progressive destruction involved in moderate to severe gum disease.
9, 17, 18) Pregnancy outcomes were evaluated in these animals after either the establishment of experimental periodontitis, the establishment of a non-disseminating subcutaneous tissue infection with Porphyromonas gingivalis (a common gramnegative periodontal pathogen) (9) or intravenous injection of LPS from P.
