Vibrio vulnificus: Wild type vs. iscR mutant (V. vulnificus iron-sulfur cluster regulator)

ABSTRACT: IscR is a novel global regulator potentially contributing to the overall success in survival and pathogenesis of V. vulnificus by coordinating the regulation of various virulence factors. The profiles of transcripts from the V. vulnificus iscR mutant and the parental wild type were compared by using a V. vulnificus whole-genome microarray.

Vibrio vulnificus: Wild type vs. iscR mutant (V. vulnificus iron-sulfur cluster regulator)

Project description:IscR is a novel global regulator potentially contributing to the overall success in survival and pathogenesis of V. vulnificus by coordinating the regulation of various virulence factors. The profiles of transcripts from the V. vulnificus iscR mutant and the parental wild type were compared by using a V. vulnificus whole-genome microarray. Two-condition experiment: Wild type vs. iscR mutant. Biological replicates: 3 control, 3 mutant strains, independently grown and harvested. One replicate per array. For transcriptome analysis, the V. vulnificus whole genome TwinChip, manufactured and kindly provided by the 21C Frontier Microbial Genomics and Applications Center (Daejeon, South Korea), was used.

Iron regulation in Vibrio vulnificus CMCP6

Project description:Vibrio vulnificus multiply rapidly in host tissues under iron overloaded conditions. To understand the effects of iron in the physiology of this pathogen we performed a genome-wide transcriptional analysis of this bacterium growing under three different iron concentrations. V.vulnificus CMCP6 cells were grown under three different iron concentrations (TSBS + EDDA 50uM, TSBS and TSBS + FAC 250 ug/ml) and samples taken at log phase. Keywords: Response to the iron concentration of the media Strains were grown to an OD600nm of 0.6 to 0.8 in TSBS, TSBS with the addition of 250 Î¼g/ml FAC or TSBS with the addition of 50 Î¼M EDDA. Three independent cultures of the V. vulnificus cells grown in each media, were combined and treated as a single sample for the RNA extraction to minimize culture variation. Two samples per condition were used for the microarray analysis. Cells were centrifuged and the pellets resuspended in RNAWiz reagent (AmbionÂ®, Austin, TX). Total RNA was extracted from each strain according to the manufacturerâ??s instructions

Vibrio vulnificus: Wild-type vs. smcR mutant (V. vulnificus quorum sensing master regulator)

Project description:Two-condition experiment, Wild-type vs. smcR mutant. Biological replicates: 3 control, 3 mutant strains, independently grown and harvested. One replicate per array. A significant portion of the SmcR regulon predicted on the basis of microarray analysis results is indeed regulated by SmcR and that SmcR is a global regulator in V. vulnificus. For transcriptome analysis, the V. vulnificus whole genome TwinChip, manufactured and kindly provided by the 21C Frontier Microbial Genomics and Applications Center(Daejeon, South Korea), was used.

Vibrio vulnificus Wild-type vs. smcR mutant biofilm cells (V. vulnificus quorum sensing master regulator)

Project description:Two-condition experiment, Wild-type biofilm cells vs. smcR mutant biofilm cells. Biological replicates: 3 control, 3 mutant strains, independently grown and harvested. One replicate per array. A significant portion of the SmcR regulon predicted on the basis of microarray analysis results is indeed regulated by SmcR and that SmcR functions on biofilm dispersion in V. vulnificus. For transcriptome analysis, the V. vulnificus whole genome TwinChip, manufactured by e-biogen (Seoul, South Korea), was used.

Transcriptomic analysis of Vibrio vulnificus in response to iron concentration and Fur protein

Project description:V. vulnificus is a marine bacteria that causes diseases in both mammals and fish. In both hosts, the iron concentration represents a key factor that greatly influences the virulence of this bacterium. To further define the gene repertoire that is regulated by iron concentration and Fur protein (the main transcriptional regulator in response to iron concentration) in V. vulnificus, we obtained a mutant in Fur and used DNA microarray technology to monitor the expression of the entire gene repertoire in response to iron. Global transcriptomic response was reconstructed by comparing the transcriptional profiles of the wild-type (R99) and Fur mutant strains in poor and rich iron conditions.

European eel immune response against Vibrio vulnificus challenge

Project description:Vibriosis caused by Vibrio vulnificus on eels represents an important threat for this specie under culture conditions. Development of new transcriptomic tools is essential to increase the knowledge of eel biology, that nowadays is scarcer. Therefore, using previous results obtained by 454 sequencing of the eel immune-enriched transcriptome, an eel-specific custom microarray have been designed. Gills transcriptomic pattern were analyzed as a principal portal of entry for pathogens in fish after 1h of bath infection with Vibrio vulnificus to describe gill immune response. Moreover, two different strains were used, vibro vulnificus wild type (R99) and rtx double mutant (CT285), to asses the virulence of these pathogen caused by MARTX.
