Among the Burkholderia species, which is most commonly isolated from clinical specimens?

Explanation:
Burkholderia cepacia complex is the one most often recovered from clinical specimens, especially respiratory samples from patients with cystic fibrosis. It persists in moist environments and in healthcare settings, so it’s a common opportunistic pathogen encountered in the lab. The other species are associated with specific disease scenarios—glanders from Burkholderia mallei, melioidosis from Burkholderia pseudomallei, and various infections from Burkholderia gladioli—but they are far less frequently isolated in routine clinical specimens. So, the organism most commonly isolated among these options is Burkholderia cepacia.
