View source for Burkholderia cepacia complex

== Background ==

* [[Stain::Gram-negative]] [[Shape::bacillus]]
* Classified into nine genomovars (phenotypically similar but genotypically distinct)
** [[Burkholderia cenocepacia]] (genomovar III)
** [[Burkholderia multivorans]] (genomovar II)
** [[Burkholderia dolosa]] (genomovar VI) 
* Multiple mechanisms of resistance:
** β-lactamases
** RND efflux pumps
** Altered LPS conferring polymixin resistance
** Gyrase mutations conferring fluoroquinolone resistance

== Clinical Manifestations ==

* Opportunistic lung infections, primarily of [[cystic fibrosis]] and [[lung transplant]] patients
* Colonizes the lungs of patients with [[cystic fibrosis]] and portends a poor prognosis

== Management ==

* Should be guided by antimicrobial susceptibility testing
* Antibiotic options include:
** [[TMP-SMX]] (preferred, if susceptible)
** [[Ceftazidime]] and [[ceftazidime-avibactam]]
** [[Meropenem]] and [[imipenem]]
** [[Minocycline]]
