What are the general characteristics of Proteobacteria?
Characteristics. All “Proteobacteria” are Gram-negative (though some may stain Gram-positive or Gram-variable in practice), with an outer membrane mainly composed of lipopolysaccharides. Many move about using flagella, but some are nonmotile or rely on bacterial gliding.
What family is Burkholderia?

What characteristics unify bacteria in the Proteobacteria?
Alphaproteobacteria. The first class of Proteobacteria is the Alphaproteobacteria. The unifying characteristic of this class is that they are oligotrophs, organisms capable of living in low-nutrient environments such as deep oceanic sediments, glacial ice, or deep undersurface soil.
Where is Betaproteobacteria found?
Betaproteobacteria play a role in nitrogen fixation in various types of plants, oxidizing ammonium to produce nitrite- an important chemical for plant function. Many of them are found in environmental samples, such as waste water or soil.
What does Proteobacteria do in the gut?
The Proteobacteria are thought to play a key role in preparing the gut for colonization by the strict anaerobes required for healthy gut function by consuming oxygen, and lowering redox potential in the gut environment (Shin et al., 2015).
How do people get B. cepacia?
cepacia complex. Research has shown that people with CF can get B. cepacia from others who are infected with these bacteria. The germs spread either by direct contact, such as kissing, or indirectly from touching objects with the germs, such as doorknobs.
Which of the following characteristics distinguish the Archaea from the bacteria?
Archaea is differing from bacteria because the cell wall of archaea does not contain peptidoglycan and cell membrane uses ether linked lipids while the cell membrane of bacteria uses ester linked lipids.
Are Betaproteobacteria aerobic?
Betaproteobacteria includes groups of Gram-negative aerobic or facultative bacteria that often have versatile degradation capacities, including, in particular, the genus Burkholderia, which includes species pathogenic in humans and animals, such as B.
Is Proteobacteria unicellular or multicellular?
Mostly unicellular, but some can form cellular aggregates. Motile rods; strictly anaerobic chemoorganotrophs or chemolithotrophs.
What kind of bacteria are the Burkholderiales?
The Burkholderiales are an order of Proteobacteria. Like all Proteobacteria, they are Gram-negative. They include several pathogenic bacteria, including species of Burkholderia, Bordetella, and Ralstonia. They also include Oxalobacter and related genera, which are unusual in using oxalic acid as their source of carbon..
What kind of diet causes Burkholderiales to increase?
In particular, C. varians colonies fed a diet enriched in bee pollen showed increased abundance of some Rhizobiales symbionts, and concomitant decreases in the proportions of some Burkholderiales.
Are there any associations between Burkholderiales and paediatric patients?
For CD we found no association for paediatric patients, while there was a weak association for an unclassified group of Burkholderiales for adults (p = 0.07).
Is it possible to isolate Burkholderia cepacia pseudomallei?
B. pseudomallei not ruled out, especially if colonies have musty odor. B. pseudomallei is separated from B. cepacia by a susceptible amoxicillin-clavulanate test.Although rare in B. pseudomallei, resistance cannot rule out the identification. Contact your LRN Reference Level Laboratory to refer isolate.
