Abstract :
Background: Gram-negative bacteria are a major cause of pulmonary infection in patients with cystic fibrosis (CF).
Objectives: The study aimed to conduct the molecular identification of Gram-negative bacterial flora causing pulmonary infection
in children with CF.
Methods: In this study, sputum samples were taken from 64 CF children undergoing treatment as outpatients or inpatients at a
referral children’s hospital in Tehran. The PCR technique was used to detect the presence of Gram-negative bacteria, namely Pseudomonas
spp., Acinetobacter baumannii, Stenotrophomonas maltophilia, and Burkholderia cepacia.
Results: All samples were positive for 16srRNA. Pseudomonas spp. and A. baumannii were detected in 47% and 14% of the studied
samples, respectively. Co-colonization by Pseudomonas spp. and A. baumannii was observed in three (5%) samples.
Conclusions: According to this survey, Pseudomonas spp. were the most prevalent Gram-negative bacteria isolated from CF patients
with pulmonary infection by molecular assays.
