TranslationsBacteroides
Bacteroides [bak″tĕ-roi´dēz] a genus of gram-negative, anaerobic, rod-shaped bacteria. Organisms are part of the normal flora of the oral, respiratory, intestinal, and urogenital cavities of humans and animals; some species are potential pathogens, causing possibly fatal abscesses and bacteremias. Pathogenic species include B. asaccharoly´ticus; B. fra´gilis, the most common anaerobic bacterium causing human infection, most frequently implicated in intra-abdominal infections, but found in bacteremias, abscesses, and other lesions throughout the body; B. fundibulifor´mis, an animal pathogen also found in chronic ulcer of the colon in humans; B. melaninoge´nicus, which occurs in oral, lung, and brain abscesses and in mixed infections; and B. thetaiotaomi´cron, the second most common anaerobic bacterium causing human infection (after B. fragilis).
bacteroides [bak″tĕ-roi´dēz] 1. any rod-shaped bacteria that can take many different shapes.2. an organism of the genus Bacteroides.Bacteroides (bak'ter-oy'dēz), A genus that includes many species of obligate anaerobic, non-spore-forming bacteria (family Bacteroidaceae) containing gram-negative rods. Both motile and nonmotile species occur; motile cells are peritrichous. Some species ferment carbohydrates and produce combinations of succinic, lactic, acetic, formic, or propionic acids, sometimes with short-chained alcohols; butyric acid is not a major product. Those species that do not ferment carbohydrates produce from peptone either trace to moderate amounts of succinic, formic, acetic, and lactic acids or major amounts of acetic and butyric acids with moderate amounts of alcohols and isovaleric, propionic, and isobutyric acids. They are part of the normal flora of the intestinal tract and to a lesser degree, the respiratory and urogenital cavities of humans and animals; many species formerly classified as Bacteroides have been reclassified as belonging to the genus Prevotella. Many species can be pathogenic. The type species is Bacteroides fragilis.

A number of Bacteroides species have been reclassified as belonging to the genus Prevotella. Many species can be pathogenic. The type species is B. fragilis. [G. bacterion + eidos, form]Bacteroides A genus of GRAM NEGATIVE, non-motile, ANAEROBIC bacteria normally occurring in the mouth and digestive tract. Some species can cause disease.Bacteroides a GENUS of ANAEROBIC, Gram-negative BACTERIA (see GRAM'S STAIN), found in man and other animals. Some SPECIES are OPPORTUNISTIC PATHOGENS. INFECTIONS due to Bacteroides are often a cause of peritonitis.Bac·te·roi·des (bak-ter-oy'dēz) A genus that includes many species of obligate anaerobic, non-spore-forming bacteria containing gram-negative rods.
