Gram-Negative Anaerobic Straight, Curved, and Helical Rods

Medical Definition: A group of anaerobic, rod-shaped bacteria that show up as pink (negative) when treated by the Gram-staining method.
Guide Notes: avoid: too general; prefer specific families & genera; coord IM with GRAM-NEGATIVE BACTERIAL INFECTIONS (IM); DF: GRAM NEG ANAEROBIC RODS
Previously Indexed: Gram-Negative Anaerobic Bacteria (1992-1997)
Gram-Negative Anaerobic Straight, Curved, and Helical Rods Categories.
Canadian Medical Guide Definition Acidaminococcaceae - A family of gram-negative bacteria, in the order Clostridiales.
Canadian Medical Guide Definition Anaerobiospirillum - A genus of gram-negative, spiral-shaped bacteria in the family SUCCINIVIBRIONACEAE. It has been isolated from the THROAT and COLON of beagle dogs and from human FECES.
Canadian Medical Guide Definition Bilophila - A genus of gram-negative, anaerobic bacteria in the family Desulfovibrionaceae. It was originally recovered from infections in patients with gangrenous and PERFORATED APPENDICITIS. It is also associated with ABSCESS; BACTEREMIA; and BILIARY TRACT sepsis.
Canadian Medical Guide Definition Butyrivibrio - A species of anaerobic bacteria, in the family Lachnospiraceae, found in RUMINANTS. It is considered both gram-positive and gram-negative.
Canadian Medical Guide Definition Chromatium - A genus of gram-negative, ovoid to rod-shaped bacteria that is phototrophic. All species use ammonia as a nitrogen source. Some strains are found only in sulfide-containing freshwater habitats exposed to light while others may occur in marine, estuarine, and freshwater environments.
Canadian Medical Guide Definition Desulfovibrio - A genus of gram-negative, anaerobic, rod-shaped bacteria capable of reducing sulfur compounds to hydrogen sulfide. Organisms are isolated from anaerobic mud of fresh and salt water, animal intestines, manure, and feces.
Canadian Medical Guide Definition Desulfuromonas - A genus of gram-negative, anaerobic, nonsporeforming bacteria in the family Desulfuromonadaceae. It is found in anoxic marine sediments.
Canadian Medical Guide Definition Dichelobacter nodosus - A gram-negative, obligate anaerobe of the family Cardiobacteriaceae. It has polar fimbriae and is the causative agent of ovine FOOT ROT. It is the lone species in the genus Dichelobacter.
Canadian Medical Guide Definition Ectothiorhodospiraceae - A family in the order Chromatiales, class GAMMAPROTEOBACTERIA. These are haloalkaliphilic, phototrophic bacteria that deposit elemental sulfur outside their cells.
Canadian Medical Guide Definition Fibrobacter - A genus of gram-negative, anaerobic bacteria in the family Fibrobacteraceae, isolated from the human GASTROINTESTINAL TRACT.
Canadian Medical Guide Definition Geobacter - A genus of gram-negative, anaerobic, metal-reducing bacteria in the family Geobacteraceae. They have the ability to oxidize a variety of organic compounds, including AROMATIC HYDROCARBONS.
Canadian Medical Guide Definition Oxalobacter formigenes - The sole species of the genus Oxalobacter consisting of straight or curved gram-negative rods with rounded ends. Cells are nonmotile, nonsporing, and use OXYLATES as the only source of CARBON and energy, with formate and CARBON DIOXIDE as end products. They are isolated from lake sediments and from the rumen or large bowel of humans and animals. (From Bergey's Manual of Determinative Bacteriology, 9th ed)
Canadian Medical Guide Definition Spirochaetaceae - A family of spiral bacteria of the order SPIROCHAETALES.
Canadian Medical Guide Definition Succinivibrionaceae - A family of gram-negative, rod-shaped bacteria isolated from the RUMEN of SHEEP and CATTLE and from human FECES. They are chemoorganotrophic and strictly anaerobic.
Canadian Medical Guide Definition Thauera - A genus of gram-negative, rod-shaped bacteria able to anaerobically oxidize and degrade toluene.
Canadian Medical Guide Definition Thermotoga maritima - A rod-shaped bacterium surrounded by a sheath-like structure which protrudes balloon-like beyond the ends of the cell. It is thermophilic, with growth occurring at temperatures as high as 90 degrees C. It is isolated from geothermally heated marine sediments or hot springs. (From Bergey's Manual of Determinative Bacteriology, 9th ed)
Canadian Medical Guide Definition Wolinella - A genus of gram-negative, anaerobic, rod-shaped bacteria isolated from the bovine RUMEN, the human gingival sulcus, and dental PULPITIS infections.
