Abstract
Six transtracheal aspirations (TTA) and expectorated sputum specimens were collected from 4 children suffering from cystic fibrosis who had pulmonary infection. Specimens obtained from both sites were cultured for aerobic bacteria and TTA aspirates were also cultured for anaerobes. Differences in bacteria isolated in TTA and sputum aspirates were present in all instances. Six isolates were recovered in both sites (3 Pseudomonas aeruginosa, 2 Staphylococcus aureus and 1 Aspergillus flavus). Five aerobic isolates were recovered only in the expectorated sputum and not in TTA aspirations (2 Klebsiella pneumoniae and 1 each of P. aeruginosa, Escherichia coli and Proteus mirabilis). Nine organisms were isolated only from the TTA (2 each of Veillonella parvula and .alpha. hemolytic streptococci, and 1 each of Bacteroides fragilis, B. melaninogenicus, Lactobacillus sp., Haemophilus influenzae and .gamma. hemolytic streptococci). The recovery of anaerobic organisms from 4 of the 6 TTA specimens suggests a possible role for these organisms in the etiology of pulmonary infection in cystic fibrosis. TTA was helpful in the bacterial diagnosis and management of pulmonary infections in cystic fibrosis.
