Project description:Small octopus is one of the major source for V. vulnificus outbreak among aquatic products in Northeast Asian due to improperly cooking and wound infection by mishandling. However, there is no report on whole genome sequence of V. vulnificus isolated from contaminated surf clam, thus no information is available for major virulence factors about V. vulnificus obtained from small octopus. Therefore, the analysis of transcriptome of isolated V. vulnificus from products are necessary to investigate potential risk of foodborne illness by contaminated products.

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.

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.

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: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.

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.

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:Vibrio vulnificus is an foodborne pathogen that can cause gastroenteritis and septicemia in humans. V. vulnificus secretes a multifunctional autoprocessing repeats-in-toxin (MARTX) toxin as an essential virulence factor to cause disease. MARTX toxins are pore-forming toxins that translocate multiple functionally independent effector domains into a target cell. MARTX toxins of V. vulnificus can contain anywhere from 3 to 5 of the 10 identified effector domains and strains with different effector repertories having varying virulence potential. The goal of this study was to compare how different effector combinations from an F-type MARTX toxin differentially remodel the transcriptional response of human intestinal epithelial cells (IECs). F-type MARTX toxins contain five effector domains – the actin crosslinking domain (ACD), two copies the makes caterpillar floppy-like domain (MCF), and alpha-beta hydrolase (ABH) domain, and the Ras/Rap1 specific endopeptidase (RRSP). Cultured human IECs were treated with V. vulnificus or strains modified to secrete a toxin with only ACD, ACD with MCF-ABH, ACD with RRSP, or no active effectors. We demonstrate that when no active effectors are present, the bacterium induces minimal changes in the transcriptional profile of IECs. However, the strains containing different effector combinations each uniquely remodeled the transcriptional profile of IECs. These data provide insight into how V. vulnificus strains with varying effector combinations can differentially regulate the host cell response to cause disease.

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.
