How common is Burkholderia cepacia?
Burkholderia cepacia, a bacteria which used to be called Pseudomonas cepacia, is a rare but significant threat to people living with cystic fibrosis (CF). While the infection is most often symptom-free, it can turn serious, and even life-threatening.
What antibiotics treat Burkholderia?
Infections due to Bcc can be challenging to manage, as Bcc is intrinsically resistant to a number of commonly used antibiotics. Trimethoprim-sulfamethoxazole (TMP-SMX) and ceftazidime are considered first-line options for Bcc infections (1).

In general, Burkholderia manifests innate resistance to aminoglycoside antibiotics and widespread resistance to many beta-lactam agents, including extended-spectrum penicillins such as piperacillin and the 4th generation cephalosporin cefepime.
Is Burkholderia cepacia aerobic or anaerobic?
Burkholderia cepacia is an aerobic gram-negative bacillus found in various aquatic environments. B cepacia is an organism of low virulence and is a frequent colonizer of fluids used in the hospital (eg, irrigation solutions, intravenous fluids). B cepacia rarely causes infection in healthy hosts.
Does Burkholderia cepacia require isolation?
cepacia” should be avoided. Although the guidelines also state that patients harboring multiresistant organisms require isolation, the risk of B. cepacia transmission to or from non-CF patients is not specifically addressed.
How many Burkholderia species are there?
Many other species of Burkholderia have been described since the discovery of B. cepacia by W.H. Burkholder and there are currently more than 40 validly described species (see http://www.bacterio.cict.fr/b/burkholderia.html for an up-to-date overview).
