1. Polyphasic characterisation of Burkholderia cepaciacomplex species isolated from children with cystic fibrosis
Cystic fibrosis (CF) patients with Burkholderia cepacia complex (Bcc) pulmonary infections have high morbidity and mortality. The aim of this study was to compare different methods for identification of Bcc species isolated from paediatric CF patients. Oropharyngeal swabs from children with CF were used to obtain isolates of Bcc samples to evaluate six diffe

3. Complexo Burkholderia cepacia em pacientes com fibrose cística em um Centro de Referência no Brasil : identificação, prevalência e importância clínica / Burkholderia cepacia complex in cystic fibrosis patients in a Brazilian Preference Center : identification, prevalence and clinical relevance
Objetivos: Determinar a prevalência da colonização/infecção pelo Complexo Burkholderia cepacia (CBc) e os respectivos genomovares em pacientes com fibrose cística (FC) e comparar os indicadores clínicos, nutricionais, tomográficos e funcionais de gravidade da lesão pulmonar em dois grupos de pacientes: GI: pacientes colonizados/infectados pelo CBc e

4. Diversidade de bactérias Burkholderia em solo de Terra Preta Arqueológica da Amazônia por análise em gel de poliacrilamida com gradiente desnaturante (DGGE) e sequenciamento / The bacterial diversity of Burkholderia in Archeological Black Earth determined by denaturing gradient gel eletrophoresis (DGGE) and DNA sequencing
Dentre os vários microrganismos que fazem parte de microecossistemas de solos, as bactérias do gênero Burkholderia apresentam-se de interesse por possuírem amplo potencial agrícola e biotecnológico. São portadores de uma infinidade de características, como por exemplo: promotoras de crescimento em plantas com a fixação biológica do nitrogênio e p

5. Quorum-Sensing Signals and Quorum-Sensing Genes in Burkholderia vietnamiensis
Acyl-homoserine lactone (acyl-HSL) quorum sensing is common to many Proteobacteria including a clinical isolate of Burkholderia cepacia. The B. cepacia isolate produces low levels of octanoyl-HSL. We have examined an environmental isolate of Burkholderia vietnamiensis. This isolate produced several acyl-HSLs. The most abundant species was decanoyl-HSL. Decan

6. Discrimination of Burkholderia multivorans and Burkholderia vietnamiensis from Burkholderia cepacia Genomovars I, III, and IV by PCR
We present a PCR procedure for identification of Burkholderia cepacia, Burkholderia multivorans, and Burkholderia vietnamiensis. 16S and 23S ribosomal DNAs (rDNAs) of B. multivorans and B. vietnamiensis were sequenced and aligned with published sequences for definition of species-specific 18-mer oligonucleotide primers. Specific antisense 16S rDNA primers (f

7. Burkholderia, a Genus Rich in Plant-Associated Nitrogen Fixers with Wide Environmental and Geographic Distribution
The genus Burkholderia comprises 19 species, including Burkholderia vietnamiensis which is the only known N2-fixing species of this bacterial genus. The first isolates of B. vietnamiensis were recovered from the rhizosphere of rice plants grown in a phytotron, but its existence in natural environments and its geographic distribution were not reported. In the

8. Distribution of Quorum-Sensing Genes in the Burkholderia cepacia Complex
The distribution of quorum-sensing genes among strains from seven genomovars of the Burkholderia cepacia complex was examined by PCR. cepR and cepI were amplified from B. cepacia genomovars I and III, B. stabilis, and B. vietnamiensis. cepR was also amplified from B. multivorans and B. cepacia genomovar VI. bviIR were amplified from B. vietnamiensis. All gen

9. Invasion of Spores of the Arbuscular Mycorrhizal Fungus Gigaspora decipiens by Burkholderia spp.
Burkholderia species are bacterial soil inhabitants that are capable of interacting with a variety of eukaryotes, in some cases occupying intracellular habitats. Pathogenic and nonpathogenic Burkholderia spp., including B. vietnamiensis, B. cepacia, and B. pseudomallei, were grown on germinating spores of the arbuscular mycorrhizal fungus Gigaspora decipiens

10. DNA-Based Diagnostic Approaches for Identification of Burkholderia cepacia Complex, Burkholderia vietnamiensis, Burkholderia multivorans, Burkholderia stabilis, and Burkholderia cepacia Genomovars I and III
Bacteria of the Burkholderia cepacia complex consist of five discrete genomic species, including genomovars I and III and three new species: Burkholderia multivorans (formerly genomovar II), Burkholderia stabilis (formerly genomovar IV), and Burkholderia vietnamiensis (formerly genomovar V). Strains of all five genomovars are capable of causing opportunistic

11. Diagnostically and Experimentally Useful Panel of Strains from the Burkholderia cepacia Complex
Two new species, Burkholderia multivorans and Burkholderia vietnamiensis, and three genomovars (genomovars I, III, and IV) currently constitute the Burkholderia cepacia complex. A panel of 30 well-characterized strains representative of each genomovar and new species was assembled to assist with identification, epidemiological analysis, and virulence studies

12. Differentiation of Burkholderia Species by PCR-Restriction Fragment Length Polymorphism Analysis of the 16S rRNA Gene and Application to Cystic Fibrosis Isolates
Burkholderia cepacia, which is an important pathogen in cystic fibrosis (CF) owing to the potential severity of the infections and the high transmissibility of some clones, has been recently shown to be a complex of five genomic groups, i.e., genomovars I, II (B. multivorans), III, and IV and B. vietnamiensis. B. gladioli is also involved, though rarely, in
