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) |
Acidaminococcaceae - A family of gram-negative bacteria, in the order Clostridiales. | |
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. | |
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. | |
Butyrivibrio - A species of anaerobic bacteria, in the family Lachnospiraceae, found in RUMINANTS. It is considered both gram-positive and gram-negative. | |
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. | |
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. | |
Desulfuromonas - A genus of gram-negative, anaerobic, nonsporeforming bacteria in the family Desulfuromonadaceae. It is found in anoxic marine sediments. | |
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. | |
Ectothiorhodospiraceae - A family in the order Chromatiales, class GAMMAPROTEOBACTERIA. These are haloalkaliphilic, phototrophic bacteria that deposit elemental sulfur outside their cells. | |
Fibrobacter - A genus of gram-negative, anaerobic bacteria in the family Fibrobacteraceae, isolated from the human GASTROINTESTINAL TRACT. | |
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. | |
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) | |
Spirochaetaceae - A family of spiral bacteria of the order SPIROCHAETALES. | |
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. | |
Thauera - A genus of gram-negative, rod-shaped bacteria able to anaerobically oxidize and degrade toluene. | |
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) | |
Wolinella - A genus of gram-negative, anaerobic, rod-shaped bacteria isolated from the bovine RUMEN, the human gingival sulcus, and dental PULPITIS infections. |
