Gram-Negative Aerobic Bacteria
| Definition: |
A large group of aerobic bacteria which show up as pink (negative) when treated by the gram-staining method. This is because the cell walls of gram-negative bacteria are low in peptidoglycan and thus have low affinity for violet stain and high affinity for the pink dye safranine. |
| Notes: |
GEN: avoid; prefer specifics; do not use as a routine coord for a gram-negative aerobic bact; infection: coord IM with GRAM-NEGATIVE BACTERIAL INFECTIONS (IM); DF: GRAM NEG AEROBIC BACT |

Gram-Negative Aerobic Bacteria Categories.
 |
Caulobacter - A genus of gram-negative, aerobic, rod- or vibroid-shaped or fusiform bacteria that commonly produce a stalk. They are found in fresh water and soil and divide by binary transverse fission. |
|
Gallionellaceae - A family of gram-negative bacteria in the order Nitrosomonadales, class BETAPROTEOBACTERIA. It contains a single genus Gallionella. |
|
Gram-Negative Aerobic Rods and Cocci - A group of gram-negative bacteria consisting of rod- and coccus-shaped cells. They are both aerobic (able to grow under an air atmosphere) and microaerophilic (grow better in low concentrations of oxygen) under nitrogen-fixing conditions but, when supplied with a source of fixed nitrogen, they grow as aerobes. |
|
Gram-Negative Chemolithotrophic Bacteria - A large group of bacteria including those which oxidize ammonia or nitrite, metabolize sulfur and sulfur compounds, or deposit iron and/or manganese oxides. |
|
Thiotrichaceae - A family of colorless sulfur bacteria in the order Thiotrichales, class GAMMAPROTEOBACTERIA. |
|
Vitreoscilla - A genus of gram-negative, aerobic or microaerophilic, colorless filaments. It is nonfruiting, motile by gliding, and found in freshwater sediments and cow dung. One species (V. stercoraria) is considered morphologically to be a streptobacillus. That species is strictly aerobic and produces a homodimeric bacterial hemoglobin, especially under oxygen-limited growth conditions. (From Bergey's Manual of Determinative Bacteriology, 9th ed) |
