Controversias taxonómicas del género Edwardsiella: E. tarda vs. E. piscicida

Abstract

Four species (E. tarda, E. ictaluri, E. piscicida and E. anguillarum) belongin to the genus Edwardsiella, are very important for the aquaculture industry due to the several outbreaks caused by this pathogens. In this thesis, the taxonomic problems of the genus through techniques such as AFLP, MLSA and the study of the complete genome. In addition, we investigate the evolutionary process of the genus, emphasizing one of the most pathogenic species, E. pisicicida. The proteomic studies carried out in E. piscicida, 2D-DIGE and TMT6plexTM have been useful in the identification of virulence factors. Also, we collect all the available information of E. pisicicida in order to update the knowledge of this microorganism.
