Project description:The profiles of transcripts from the V. vulnificus grown under normal and high c-di-GMP conditions were compared by using a V. vulnificus whole-genome microarray Two-condition experiment, normal c-di-GMP condition vs. high c-di-GMP condition. Biological replicates: 3 control, 3 experimental, 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.

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.

Adult european eels were bath infected with two Vibrio vulnificus strains, the wild type and double Rtx mutant (CT285). After 0, 3, 12h post-infection eel gills were sampled. Three individuals per experimental point were sampled, including a Control group and a Handling control group. Obtaining a total of 24 samples. The transcriptomic profile was described for each individual sample.

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

Project description:In order to analyze the transcripts of Arabidopsis thaliana (Col-0) and Vibrio vulnificus MO6-24/O simultaneously, Vibrio vulnificus MO6-24/O was infiltrated onto Arabidopsis leaves and then leaves were harvested at 0, 3, 6, 12, 24 and 48 h post-infiltration. A total of 31, 128, 303, 219 and 130 differentially expressed genes (DEGs) of Vibrio were up- and down-regulated at 3, 6, 12, 24 and 48 h post-infiltration (hpi). Meanwhile, differentially expressed genes (DEGs) were monitored at 3, 6, 12, 24 and 48 h post-infiltration. A total of 2,097, 1,839, 1,220, 1,170 and 1,383 genes were characterized at each time points in Arabidopsis. Our data clearly indicate that total transcripts of the marine bacterial pathogen V. vulnificus MO6-24/O are detected and analyzed in plant Arabidopsis and two organisms were inter-communicated at the same time under favorable conditions.

Project description:Vibrio parahaemolyticus scr genes modulate expression of gene sets pertinent to swarming and biofilm formation. They do so by affecting the level of the second messenger c-di-GMP. Here we explore the extent of this regulation by comparing the transcriptomes of a scrABC mutant and its wild-type parental strain. The scope of transcriptional effects modulated by c-di-GMP includes ~100 genes that are positively and negatively regulated. An elevated cellular level of c-di-GMP represses the surface sensing regulon including the genes encoding the lateral flagellar and type three secretion systems while inducing expression of genes encoding cell surface molecules and capsular polysaccharide. Expression of a few transcriptional regulators was also affected, and here we describe the role of one, CpsQ. CpsQ is one of four V. parahaemolyticus homologs in the CsgD/VpsT family of regulators, members of which have been implicated in c-di-GMP signaling. Mutations in cpsQ, like defects in another previously identified capsule regulator, cpsR, suppress the sticky phenotype of scr mutants. By using a combination of mutant and reporter analyses in Vibrio and E. coli, CpsQ is shown to be the direct positive regulator of cpsA transcription and its cpsA-activating ability is found to be responsive to the cellular level of c-di-GMP. Unexpectedly, we find that a low level of this nucleotide diminishes the stability of CpsQ. The molecular interplay in this signaling circuit is further defined by demonstrating that CpsQ is epistatic to CpsS, a negative regulator of capsule. CpsR activates cpsQ, and CpsQ can also regulate its own transcription. Wildtype Vibrio parahaemolyticus (LM5674) and scrABC mutant (LM6567) were grown on rich mediim agar plates and gene expression profiles were compared.

Project description:VarS/A is one of the global factors regulating diverse aspects of metabolism and virulence of bacteria including pathogenic Vibrio spp. An experiment to identify VarS/A-regulon in V. vulnificus revealed that a putative LuxR-type transcriptional regulator was down-regulated in ΔvarA mutant. To investigate the roles of this regulatory cascade from VarS/A to a LuxR-type regulator in V. vulnificus, the target gene regulated by a LuxR-regulator was identified and its expression was characterized.
