Clonal diversity among Burkholderia cepacia complex isolates from cystic fibrosis patients in a reference unit.

چکیده
INTRODUCTION The epidemiology of Burkholderia cepacia complex (Bcc) in cystic fibrosis (CF) is not widely known. METHODS All CF patients with Bcc between 2002 and 2011 were reviewed, and a molecular analysis of isolates was performed. RESULTS The prevalence of Bcc infection was 7.2% (18/250). Molecular analysis of 16 Bcc isolates showed 5 species (7 B. contaminans, 6 B. cepacia, 1 B. cenocepacia, 1 B. multivorans, and 1 B. stabilis) and 13 sequence types. There were no cases of cross-transmission. CONCLUSION A high diversity of Bcc species was found in infected CF patients.

Burkholderia cepacia complex (Bcc) is a complex group of bacteria causing opportunistic infections in immunocompromised and cystic fibrosis (CF) patients. Herein, we report multilocus sequence typing and analysis of the 57 clinical isolates of Bcc collected over the period of seven years (2005-2012) from several hospitals across India. A total of 21 sequence types (ST) including two STs from cy...

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...

A total of 120 Burkholderia cepacia complex isolates collected during 2004-2010 from 66 patients in two cystic fibrosis reference centers in Argentina were analyzed. Burkholderia contaminans was the species most frequently recovered (57.6%), followed by Burkholderia cenocepacia (15%), a species distribution not reported so far. The recA-PCR-based techniques applied to the B. contaminans isolate...

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...
متن کاملPhenotypic methods for determining genomovar status of the Burkholderia cepacia complex.
Recent taxonomic advances have demonstrated that Burkholderia cepacia is a cluster of at least seven closely related genomic species (or genomovars) collectively referred to as the B. cepacia complex, all of which may cause infections among cystic fibrosis patients and other vulnerable individuals. Thus, it is important for clinical microbiologists to be able to differentiate genomovars. Prior ...
