Project description:Edwardsiella tarda is a Gram-negative bacterial pathogen that can infect a wide range of freshwater and marine fish. However, the immune evasion mechanisms of Edwardsiella tarda is not fully understood. We found that Edwardsiella tarda infection generally significantly upregulated and downregulated a lot of immune-related genes of zebrafish ZF4 cells using RNA-seq technology.
Project description:In this study we analyzed the zebrafish embryonic host response induced by E. tarda (FL6-60) immersion. The E. tarda induced transcriptome profile was compared to those induced by either E. coli or Pseudomonas aeruginosa immersion using the same experimental setup.
Project description:Gene expression profiles by microarray have contributed for a elucidation of an immune-response and a determination of efficiency in vaccination. Recent day, edwardsielosis have caused a fatal damage in the aquaculture of Japanese flounder, Paralichthys olivaceus. However the formalin killed-cell vaccines made from Edwardsiella tarda isolated same fish species were not efficient. Recent our study revealed the mixed FKC vaccine made from the two different type of E. tarda protected Japanese flounder against Edwardsiella tarda infection for long-term. In this study, we analyzed the immune-response of a vaccinated fish kidney using the mixed FKC vaccine against Edwardsiella tarda with an Agilent custom-oligo DNA microarray on 9,573 probes of Japanese flounder. Our study revealed that the mixed FKC vaccine confered a strong immune-response and keeped a efficient for long-term on Japanese flounder.
