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. 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.

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:Compare the secreted proteins of a wild-type Vibrio parahaemolyticus strain with those of a mutant in hcp2, rendering the T6SS2 inactive
Project description:In order to gain a better understanding of the impact of Vibrio parahaemolyticus infection on genetic regulation of Litopenaeus vannamei,we performed a transcriptome analysis in the hepatopancreas of Litopenaeus vannamei challenged with Vibrio parahaemolyticus, using the Illumina HiSeq 2500 platform.
