Burkholderia cepacia complex nasal isolation in immunocompetent patients with sinonasal polyposis not associated with cystic fibrosis.

The article studies the nasal microbiology of patients with sinonasal polyposis and chronic sinusitis treated with functional endoscopic sinus surgery (FESS). The isolation rate of Burkholderia cepacia complex (Bcc), a gram-negative bacteria, in sinonasal polyposis patients without cystic fibrosis is examined. The pre-operative and post-operative cultures of the species including Staphylococcus aureus, Bcc, Pseudomonas aeruginosa and others are also studied.
