What disease is Bacteroides Forsythus an agent for?
Bacteroides forsythus is a gram-negative, anaerobic, fusiform bacterium and is considered to be an etiological agent in periodontal disease.
Where is Porphyromonas gingivalis found?
P. gingivalis is mainly found during gingival and periodontal infections; however, it can also be found at low levels in 25% of healthy individuals with no oral disease (18).
What is Bacteroides gingivalis?
Bacteroides (Porphyromonas) gingivalis and Bacteroides (Porphyromonas) intermedius have been implicated in the etiology of human periodontal diseases. These organisms are able to bind and degrade human fibrinogen, and these interactions may play a role in the pathogenesis of periodontal disease.
What is the origin of the term red complex bacteria?
The red complex is a group of bacteria that are categorized together based on their association with severe forms of periodontal disease. The red complex—among a number of other complexes—were classified by Sigmund Socransky in 1998.
Is Tannerella forsythia motile?
Tannerella forsythia is a non-motile bacterium with filamentous cell morphology when grown with external supply of the essential cell wall sugar N-acetylmuramic acid (MurNAc) .
How do you get Fusobacterium nucleatum?
Fusobacterium nucleatum is an oral bacterium, commensal to the human oral cavity, that plays a role in periodontal disease. This organism is commonly recovered from different monocultured microbial and mixed infections in humans and animals.
How does P. gingivalis cause periodontitis?
gingivalis is a gram-negative oral anaerobe and considered as a main etiological factor in periodontal diseases by producing a number of virulence factors and extracellular proteases such as lipopolysaccharide, fimbria, gingipain etc., resulting in destruction of periodontal tissues (7–11).
What does P. gingivalis cause?
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.
What bacteria is orange?
Serratia marcescens (/səˈreɪʃiə mɑːrˈsɛsɪnz/) is a species of rod-shaped, Gram-negative bacteria in the family Yersiniaceae. It is a facultative anaerobe and an opportunistic pathogen. It was discovered in 1819 by Bartolomeo Bizio in Padua, Italy.
What is a pathogen in dentistry?
From Wikipedia, the free encyclopedia. Well studied Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis. Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses.
