1. New PHA products using unrelated carbon sources
Polyhydroxyalkanoates (PHA) are natural polyesters stored by a wide range of bacteria as carbon source reserve. Due to its chemical characteristics and biodegradability PHA can be used in chemical, medical and pharmaceutical industry for many human purposes. Over the past years, few Burkholderia species have become known for production of PHA. Aside from tha

2. Molecular Typing of, and Distribution of Genetic Markers among, Burkholderia cepacia Complex Isolates from Brazil
PCR tests were used to assign genomovar status to 39 non-cystic fibrosis (non-CF) and 11 CF Burkholderia cepacia complex isolates from patients in hospitals in Recife, Brazil. Non-CF isolates were assigned to genomovar IIIA (71.8%), genomovar I (15.4%), B. vietnamiensis (7.7%), and B. multivorans (5.1%). CF isolates were assigned to genomovar IIIA (18.2%), B

3. Identification and Population Structure of Burkholderia stabilis sp. nov. (formerly Burkholderia cepacia Genomovar IV)
The Burkholderia cepacia complex currently comprises five genomic species, i.e., B. cepacia genomovar I, B. multivorans (formerly known as B. cepacia genomovar II), B. cepacia genomovar III, B. cepacia genomovar IV, and B. vietnamiensis (also known as B. cepacia genomovar V). In the absence of straightforward diagnostic tests for the identification of B. cep

4. 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

5. Comparative Assessment of Genotyping Methods for Epidemiologic Study of Burkholderia cepacia Genomovar III
We analyzed a collection of 97 well-characterized Burkholderia cepacia genomovar III isolates to evaluate multiple genomic typing systems, including pulsed-field gel electrophoresis (PFGE), BOX-PCR fingerprinting and random amplified polymorphic DNA (RAPD) typing. The typeability, reproducibility, and discriminatory power of these techniques were evaluated,

6. Salicylate induces an antibiotic efflux pump in Burkholderia cepacia complex genomovar III (B. cenocepacia)
An antibiotic efflux gene cluster that confers resistance to chloramphenicol, trimethoprim, and ciprofloxacin has been identified in Burkholderia cenocepacia (genomovar III), an important cystic fibrosis pathogen. Five open reading frames have been identified in the cluster. There is apparently a single transcriptional unit, with llpE encoding a lipase-like

7. Quorum-Sensing System and Stationary-Phase Sigma Factor (rpoS) of the Onion Pathogen Burkholderia cepacia Genomovar I Type Strain, ATCC 25416
Bacterial strains belonging to Burkholderia cepacia can be human opportunistic pathogens, plant pathogens, and plant growth promoting and have remarkable catabolic activity. B. cepacia consists of several genomovars comprising what is now known as the B. cepacia complex. Here we report the quorum-sensing system of a genomovar I onion rot type strain ATCC 254

8. Impact of mutS Inactivation on Foreign DNA Acquisition by Natural Transformation in Pseudomonas stutzeri
In prokaryotic mismatch repair the MutS protein and its homologs recognize the mismatches. The mutS gene of naturally transformable Pseudomonas stutzeri ATCC 17587 (genomovar 2) was identified and characterized. The deduced amino acid sequence (859 amino acids; 95.6 kDa) displayed protein domains I to IV and a mismatch-binding motif similar to those in MutS

9. Comparative Genetic Diversity of Pseudomonas stutzeri Genomovars, Clonal Structure, and Phylogeny of the Species
A combined phylogenetic and multilocus DNA sequence analysis of 26 Pseudomonas stutzeri strains distributed within the 9 genomovars of the species has been performed. Type strains of the two most closely related species (P. balearica, former genomovar 6, and P. mendocina), together with P. aeruginosa, as the type species of the genus, have been included in t

10. Enhanced Susceptibility to Pulmonary Infection with Burkholderia cepacia in Cftr−/− Mice
Progressive pulmonary infection is the dominant clinical feature of cystic fibrosis (CF), but the molecular basis for this susceptibility remains incompletely understood. To study this problem, we developed a model of chronic pneumonia by repeated instillation of a clinical isolate of Burkholderia cepacia (genomovar III, ET12 strain), an opportunistic gram-n

11. Identification of Burkholderia cenocepacia Genes Required for Bacterial Survival In Vivo
Burkholderia cenocepacia (formerly Burkholderia cepacia complex genomovar III) causes chronic lung infections in patients with cystic fibrosis. In this work, we used a modified signature-tagged mutagenesis (STM) strategy for the isolation of B. cenocepacia mutants that cannot survive in vivo. Thirty-seven specialized plasposons, each carrying a unique oligon

12. Burkholderia cepacia Produces a Hemolysin That Is Capable of Inducing Apoptosis and Degranulation of Mammalian Phagocytes
Burkholderia cepacia is an opportunistic pathogen that has become a major threat to individuals with cystic fibrosis (CF). In approximately 20% of patients, pulmonary colonization with B. cepacia leads to cepacia syndrome, a fatal fulminating pneumonia sometimes associated with septicemia. It has been reported that culture filtrates of clinically derived str
