Aggressive periodontitis is a destructive disease characterized by the following: the involvement of multiple teeth with a distinctive pattern of periodontal tissue loss; a high rate of disease progression; an early age of onset; and the absence of systemic diseases.
What pathogen causes periodontitis?
The bacteria associated with periodontal diseases are predominantly gram-negative anaerobic bacteria and may include A. actinomycetemcomitans, P. gingivalis, P.
What bacteria initiates gingivitis?
Etiology. Periodontal infections are usually mixed, most often involving anaerobes such as Treponema denticola and Porphyromonas gingivalis. The microaerophile Actinobacillus actinomycetemcomitans causes a rare form known as localized juvenile periodontitis.
What are red complex bacteria?
The ‘red complex’ is an aggregate of three oral bacteria (Tannerella forsythia, Porphyromonas gingivalis and Treponema denticola) responsible for severe clinical manifestation of periodontal disease.
What does Treponema Denticola do?
Treponema denticola is a spirochete bacterium associated with progression of periodontal diseases, infectious diseases that destroy attachment of teeth. When the proteolytic activity of T. denticola was analyzed with a range of peptide and protein substrates a powerful proteinase was discovered [1].
Is Fusobacterium nucleatum Gram positive or negative?
Fusobacterium nucleatum, the first Gram-negative bacterium demonstrated to produce polyglutamate.
What causes Prevotella bivia in vagina?
Prevotella bivia (P. vivia) has a high proliferative potential in the presence of estrogen. Therefore, its involvement in vaginal tract infections, such as endometritis and pelvic inflammatory disease, has been well described in the literature.
How do you increase Alistipes?
A diet that includes animal protein, for example, correlates with overall microbial diversity. It increases Bacteroides, Alistipes and Bilophilas in the gut. While a high fat diet has been associated with loss of A Muciniphila and Lactobacillus, which are essential to a healthy metabolism.
How do Prevotella differ from Bacteroides?
How do Prevotella differ from Bacteroides? They are sensitive to bile. What is the antimicrobial agent of choice for treating Bacteroides infections? Which of the following organisms produces concentric wavelike patterns due to swarming cells when it is cultured on agar?
Does clindamycin cover Prevotella?
Prevotella, Porphyromonas, and Other Anaerobic Gram-Negative Rods. Porphyromonas species are generally susceptible to β-lactams, clindamycin, and metronidazole [21].
Does doxycycline treat Prevotella?
All of the Prevotella strains were susceptible to amoxicillin/clavulanic acid, doxycycline and metronidazole, whereas 7/39 strains were beta-lactamase-positive and resistant to amoxicillin, 5/39 were resistant to clarithromycin and 3/39 were resistant to both moxifloxacin and levofloxacin.
What is Prevotella Timonensis?
Prevotella timonesis are obligate anaerobes, non-pigmented, non-spore-forming, non-motile, Gram negative straight rods. The 16S rRNA accession number is DG518919. These cells are able to grow on sheep blood agar plate and TSB liquid medium while growth is inhibited by bile (20%).
Are bananas a prebiotic?
Bananas. Bananas are more than a delicious fruit: They’re rich in vitamins, minerals, and fiber, and they contain small amounts of inulin. Unripe (green) bananas are high in resistant starch, which has prebiotic effects ( 37 ).

What is a commensal pathogen?
Commensal bacteria act on the host’s immune system to induce protective responses that prevent colonization and invasion by pathogens. On the other hand, these bacteria can directly inhibit the growth of respiratory pathogens by producing antimicrobial products/signals and competing for nutrients and adhesion sites.
What is anaerobic infection?
Anaerobic infections are common infections caused by anaerobic bacteria. These bacteria occur naturally and are the most common flora in the body. In their natural state, they don’t cause infection. But they can cause infections after an injury or trauma to the body.
