Where is Prevotella intermedia found?
Prevotella intermedia (formerly Bacteroides intermedius) is a gram-negative, obligate anaerobic pathogenic bacterium involved in periodontal infections, including gingivitis and periodontitis, and often found in acute necrotizing ulcerative gingivitis.
What shape is Prevotella?
are obligate anaerobic, Gram-negative rod-shaped bacteria belonging to the Prevotellaceae family. The genus comprises approximately 30 species. Prevotella spp. often colonise the human oral, intestinal and urogenital floras.
What causes Prevotella?
Prevotella is a genus of Gram-negative bacteria. Prevotella spp. are members of the oral, vaginal, and gut microbiota and are often recovered from anaerobic infections of the respiratory tract. These infections include aspiration pneumonia, lung abscess, pulmonary empyema, and chronic otitis media and sinusitis.
Is Prevotella Gram positive or negative?
B thetaiotaomicron and B vulgatus are the dominant species of Bacteroides encountered, followed by B distasonis, B ovatus, and B fragilis. In animal studies, Bacteroides protects against infection with Salmonella or Shigella. Bacteroides, Prevotella, and Fusobacterium species are common in the vaginal flora.
How do you get Prevotella intermedia?
Prevotella intermedia is one of the bacterial pathogens that has been implicated to cause periodontitis and is often recovered from subgingival plaque in patients suffering from acute necrotising gingivitis, pregnancy gingivitis and chronic periodontitis (Loesche et al., 1982).
How is Prevotella treated?
Antibiotics for treating Prevotella include metronidazole, amoxycillin/clavulanate, ureidopenicilins, carbapenems, cephalosporins, clindamycin, and chloramphenicol (Pavillion). Prevotella is also well-known as a preventative agent for the bovine disease of rumen acidosis.
Does prevotella require blood to grow?
Prevotella grows well on laked blood agar with kanamycin and vancomycin (LKV) and has variable resistance to colistin. Although Prevotella spp. are largely regarded as pigmented GNARs, they can be nonpigmented as well. Pigmented Prevotella spp.
Is prevotella an Anaerobe?
Prevotella species are anaerobic Gram‐negative bacteria of the Bacteroidetes phylum, which also includes the clinically important genera Bacteroides and Porphyromonas.
Is Prevotella intermedia motile?
Prevotella intermedia is a short, round-ended nonmotile gram-negative anaerobic pathogenic rod which is less virulent and less proteolytic than P. gingivalis. Treponema denticola is a Gram-negative motile anaerobe related to periodontal lesions.
