Diversity and significance of Burkholderia species occupying diverse ecological niches

Abstract

SummaryMembers of the genus Burkholderia are versatile organisms that occupy a surprisingly wide range of ecological niches. These bacteria are exploited for biocontrol, bioremediation and plant growth promotion purposes, but safety issues regarding human infections, especially in cystic fibrosis patients, have not been solved. This minireview gives an overview of the taxonomic and ecological diversity of the genus with particular emphasis on strains belonging to the Burkholderia cepacia complex and addresses the important question whether 'good' and 'bad' strains are actually the same.

Dynamics of the bacterial community structure in the rhizosphere of a maize cultivar

“…SI_2). Members of Burkholderiales were enriched in the rhizosphere, possibly due to their versatile abilities to utilize root metabolites, degrade aromatic compounds (Goldfarb et al, 2011;Vandenkoornhuyse et al, 2007) and produce anti-microbial substances (Coenye and Vandamme, 2003). In this order, genera Massilia predominated at the early stages of succession, while Burkholderia and Variovorax increased at later growth stages (Fig.…”

The suhB gene of Burkholderia cenocepacia is required for protein secretion, biofilm formation, motility and polymyxin B resistance

“…Burkholderia cenocepacia is a member of the Burkholderia cepacia complex (Bcc), a group of closely related Gramnegative bacteria found ubiquitously in the environment (Coenye & Vandamme, 2003;Mahenthiralingam et al, 2005). Bcc members have emerged as serious respiratory multidrug-resistant pathogens in patients with cystic fibrosis (CF) (Isles et al, 1984) and chronic granulomatous disease (Guide et al, 2003).…”

A minor catalase/peroxidase from Burkholderia cenocepacia is required for normal aconitase activity

“…Burkholderia cepacia is an aerobic, Gram-negative, catalasepositive bacterium found in soil and water environments (Coenye & Vandamme, 2003). Strains identified as B. cepacia belong to a group of at least nine closely related species or genomovars, collectively referred to as the B. cepacia complex (Coenye & Vandamme, 2003).…”

“…Strains identified as B. cepacia belong to a group of at least nine closely related species or genomovars, collectively referred to as the B. cepacia complex (Coenye & Vandamme, 2003). B. cepacia complex strains have become medically important multidrug-resistant opportunistic pathogens, particularly in patients with cystic fibrosis and chronic granulomatous disease Govan & Deretic, 1996;Speert et al, 1994).…”
