NPW = nasopharyngeal wash; FBAS = fibrobronchial aspirate; TBAS = tracheobronchial aspirate; PSB = protected specimen brush; BAL = bronchoalveolar lavage; RSV = respiratory syncytial virus; VHS-1 = virus herpes simplex-1.
↵4-150 Some organisms were simultaneously isolated with more than one technique and some of these techniques (FBAS, TBAS, PSB, and BAL) allowed the identification of more than one organism.
