Project description:Comparative proteomics to identify proteins found in the media of Vibrio parahaemolyticus RIMD 2210633 bacteria with an active T6SS2 compared to bacteria with inactive T6SS2. Bacteria with an active T6SS2 are Vibrio parahaemolyticus RIMD 2210633 inwhich hcp1 was deleted to inactivate T6SS1. T6SS2 inactive bacteria are the former strain with an additional deletion in hcp2. Both strains express TfoX from an arabinose-inducible plasmid to induce T6SS2 activity.

Project description:Vibrio parahaemolyticus is a Gram-negative marine bacterium. Strain RIMD 2210633, the wild type strain of the organism, causes acute gastroenteritis in humans. Human intestinal factor bile often affects the global gene regulation in some species of enteropathogenic bacteria. To determine the genes in V. parahaemolyticus that respond to bile, we investigated the differences in the transcriptomes of the wild type strain and the vtrA-null strain grown in Luria-Bertani medium cultivated with or without 0.04% crude bile. The vtrA gene encodes the previously identified T3SS2 regulator. Our goal is to demonstrate bile regulon controlled by VtrA in V. parahaemolyticus.

Project description:Vibrio parahaemolyticus is a Gram-negative marine bacterium. A limited population of the organisms causes acute gastroenteritis in humans. Vibrio parahaemolyticus wild type strain RIMD 2210633 compared with the mutants of VtrA and VtrB have a winged helix-turn-helix DNA binding motif that genes encoded on pathogenicity island loci, at OD600=1.0 in Luria-Bertani containing medium 0.5 % NaCl at 37˚C. Our goal is to determine the VtrA or VtrB regulon. Cohybridized wild type versus vtrA or vtrB mutants on a single array. Biological replicates: three of wild type, three of vtrA mutants and three of vtrB mutants were independently grown and harvested.

Project description:Vibrio (V.) parahaemolyticus is the leading cause of seafood borne gastro-intestinal infections in humans worldwide. It is widely found in marine environments and is isolated frequently from seawater, estuarine waters, sediments and raw or insufficiently cooked seafood. Within the food chain, V. parahaemolyticus encounters different temperature conditions that might alter the metabolism and pathogenicity of the bacterium. In this study, we performed gene expression profiling of V. parahaemolyticus RIMD 2210633 after exposure to 4°C, 15°C, 20°C, 37°C and 42°C to describe the cold and heat shock response. Analysis of transcriptomics data resulted in differential expression of 19 genes at 20°C, 193 genes at 4°C, 625 genes at 42°C and 639 genes at 15°C. Thus the highest portion of significantly expressed genes was observed at 15°C and 42°C with 13.3% and 13%, respectively. Genes of many functional categories were highly regulated even at lower temperatures. Our results showed that virulence associated genes (tdh1, tdh2, toxR, toxS, vopC, T6SS1, T6SS2) remained largely unaffected by heat or cold stresses. Along with folding and temperature shock depending systems, an overall temperature depended regulation of expression could be shown. Particularly the energy metabolism was affected most by changed temperatures. Whole-genome gene expression studies of food related pathogens such as V. parahaemolyticus reveal how these pathogens react to stress impacts for prediction of its behaviour under conditions like storage and transport.

Whole-genome gene expression studies of food related pathogens such as V. parahaemolyticus reveal how these pathogens react to stress impacts for prediction of its behaviour under conditions like storage and transport. Temperature induced gene expression was detected in total bacterial RNA of V. parahaemolyticus. Five different temperatures (4°C, 15°C, 20°C, 37°C, 42°C) were used in at least 3 biological replicates (4 replicates for 37°C). Gene expression at 37°C was used for normalization.
