What are the characteristics of Pseudomonas cepacia?
Pseudomonas cepacia is an aerobic, glucose-nonfermenting Gram-negative bacillus which proliferates under conditions of minimal nutrition and can survive even in the presence of certain disinfectants. Morphological, biochemical, and growth characteristics of Pseudomonas cepacia from distilled water.
Does Burkholderia cepacia have flagella?
B. cepacia is a motile organism, and motility is mediated by polar flagella (3, 21).
Is Burkholderia cepacia Gram positive or negative?
Gram-negative bacilli
Bacteria in the genus Burkholderia are Gram-negative bacilli that include species with the potential to cause life-threatening human infections. People with cystic fibrosis (CF) are susceptible to infection by several Burkholderia species comprising the Burkholderia cepacia complex (Bcc) (LiPuma, 2005).
Is Burkholderia cepacia oxidase positive or negative?

Does Burkholderia cepacia grow on MacConkey Agar?
Burkholderia cepacia organisms grow well on standard solid media such as 5% sheep blood, chocolate, and MacConkey agars; in thioglycollate and brain-heart infusion broths; and in broth-based blood culture systems.
What shape is Burkholderia cepacia?
rod-shaped
Burkholderia cepacia are aerobic rod-shaped, free-living, motile Gram- negative bacteria ranging from 1.6- 3.2 μm. They have been found to possess multitrichous polar flagella as well as pili used for attachment.
Is Burkholderia motile?
Burkholderia pseudomallei, a facultatively intracellular pathogen, is a flagellated and motile gram-negative bacterium and is the causative agent of melioidosis in humans.
Is Burkholderia cepacia catalase-positive?
Burkholderia cepacia (B. cepacia), formerly known as Pseudomonas cepacia, is an aerobic, catalase-positive, gram-negative rod that was first isolated in 1950 as the responsible agricultural pest for onion skin rot.
What type of organism is Burkholderia?
bacteria
Burkholderia cepacia [burk-hōld–er–ee-uh si–pay–shee–uh] (also called B. cepacia) is the name for a group or “complex” of bacteria that can be found in soil and water. B. cepacia bacteria are often resistant to common antibiotics.
