Detection of Aspergillus species DNA by PCR in bronchoalveolar lavage fluid

The usefulness of a nested PCR assay for detection of Aspergillus so. DNA was evaluated in 177 bronchoalveolar lavage (BAL) fluid specimens. This test was accurate both to diagnose culture-negative BAL fluid specimens from patients with invasive pulmonary aspergillosis and to confirm culture-positive samples. However, if did not differentiate between infection and colonization.
