Project description:Burkholderia cepacia complex (Bcc) comprises opportunistic bacteria infecting hosts such as cystic fibrosis (CF) patients. Bcc long-term infection of CF patient airways has been associated with emergence of phenotypic variation. Here we studied two Burkholderia multivorans clonal isolates (D2095 and D2214) displaying different morphotypes from a chronically infected CF patient in order to evaluate traits development during lung infection.

Here we studied two Burkholderia multivorans clonal isolates (D2095 and D2214) displaying different morphotypes from a chronically infected CF patient in order to evaluate traits development during lung infection. Since the custom array described in platform GPL13356 was based on Burkholderia multivorans ATCC 17616 genome, here we performed a DNA-DNA hybridization to determine which probes of the array hybridize with our test genomes

Project description:Hfq proteins are RNA chaperones that play a critical role in post-transcription regulation of gene expression. Bacteria of the Burkholderia cepacia complex harbor two distinct and functional Hfq proteins, the Hfq and Hfq2. We have previously performed the functional analysis of Hfq and Hfq2 in the pathogen Burkholderia cenocepacia J2315. In order to examine the impacts of each RNA chaperone on the global transcriptome of B. cenocepacia J2315, we performed comparative transcriptome profile of mutants on the hfq and hfq2 genes, using as reference the wild-type strain.

Project description:Burkholderia cenocepacia sequence type 32 (ST32) represents one of the most globally distributed strains from Bukrholderia cepacia complex (Bcc), which infected 30% of Czech cystic fibrosis (CF) patients. The aim of this study was to compare gene expression in two pairs of ST32 clinical isolates that were subjected to cultivation in two different conditions, characteristic for chronic B. cenocepacia infection in CF patients. ST32 strain is known to be a problematic epidemic strain, which caused a serious outbreak at the Prague CF centre.

Here we studied two Burkholderia multivorans clonal isolates (D2095 and D2214) displaying different morphotypes from a chronically infected CF patient in order to evaluate traits development during lung infection. For expression profiling, overnight cultures of the mucoid D2095 and the nonmucoid D2214 isolates grown in SM medium were diluted to an initial OD640 nm of 0.1 into the same medium. Triplicate samples were cultured at 37ºC with 250 r.p.m. agitation for 17 h and RNA extracted from the two bacterial isolates.

Project description:The bacterial tyrosine (BY) kinase family comprises the major group of bacterial enzymes endowed with tyrosine kinase activity. We have previously shown that the BceF protein from Burkholderia cepacia IST408 belongs to this BY kinase family and is involved in the biosynthesis of the exopolysaccharide cepacian. However, little is known about the extent of regulation in the cell by this kinase protein. In order to examine this, we performed a comparative transcriptome profile between the bceF mutant and the wild-type B. cepacia IST408. As a control, the transcriptome of another exopolysaccharide-deficient mutant, which had a mutation in the bceE gene, was also determined.

For expression profiling, over-night cultures of the Burkholderia cenocepacia J2315 wild-type strain and the isogenic mutants hfq::Tp and M-NM-^Thfq2 grown in LB medium were diluted to an initial OD640 nm of 0.25 into LB medium. Triplicate samples were cultured at 37M-BM-:C with 250 r.p.m. agitation for 16 h and RNA extracted from the three bacterial isolates.
