Direct culture-independent Strain typing of Burkholderia cepacia complex in sputum samples from patients with cystic fibrosis.

چکیده
We examined if multilocus sequence typing (MLST), a method for genotyping and species identification of Burkholderia cepacia complex bacteria, could be applied directly to cystic fibrosis sputum. The redesigned nested-PCR MLST format was successfully used to accurately identify strains in 23 sputum samples, of which 8 were culture negative.

Background and Aim: Cystic fibrosis is a common hereditary and autosomal disorder. One of the factors in cystic fibrosis is Burkholderia cepacia which can be transmitted through the sharing of admitted patients with hospitalized patients. Purpose of this study, was isolation and identification of Burkholderia cepacia from respiratory secretions from Masih Daneshvari Hospital cystic fibrosis...

Background: Complex of Burkholderia cepacia is one of the main and serious causes of infections in cystic fibrosis patients that can be highly transmissible. Small hospital outbreaks are frequent and are usually due to a single contaminated environmental source. The pulsed-field gel electrophoresis (PFGE) is widely used to identify the strain emission sources in cystic fibrosis patients. The ai...
متن کاملEvidence of transmission of Burkholderia cepacia, Burkholderia multivorans and Burkholderia dolosa among persons with cystic fibrosis.
Previous studies have identified specific Burkholderia cepacia complex strains that are common to multiple persons with cystic fibrosis (CF). Such so-called epidemic strains have an apparent enhanced capacity for inter-patient spread and reside primarily in Burkholderia cenocepacia (formerly B. cepacia complex genomovar III). We sought to identify strains from B. cepacia complex species other t...

We investigated the utility of PCR to detect Burkholderia cepacia directly in sputum samples at two cystic fibrosis (CF) centers serving children and adults. Following liquefaction of the sputa by using N-acetyl-L-cysteine, DNA was isolated and analyzed by PCRs with three different primer pairs directed toward bacterial rRNA loci. Two primer pairs were putatively specific for B. cepacia. The ot...
