Detection of occult Scedosporium species in respiratory tract specimens from patients with cystic fibrosis by use of selective media.

ABSTRACT

Respiratory samples from cystic fibrosis outpatients were cultured on Sabouraud's dextrose agar (SABD) containing antibiotics, Mycosel, and Scedosporium-selective medium (SceSel+). Thirty-two (14.7%) of 218 specimens from 11/69 (15.9%) patients yielded a Scedosporium sp., most frequently Scedosporium aurantiacum (17/218). Scedosporium was recovered on SceSel+, Mycosel, and SABD from 90.6%, 50.0%, and 46.9% of the specimens tested, respectively.
