Comparative proteomic analysis of extracellular proteins of Edwardsiella tarda.
A comparison of extracellular proteins of virulent and avirulent Edwardsiella tarda strains revealed several major, virulent-strain-specific proteins. Proteomic analysis identified two of the proteins in the virulent strain PPD130/91 as flagellin and SseB, which are virulence factors in bacterial pathogens. PCR amplification and DNA sequencing confirmed the presence of the genes that encode the...
متن کاملRole of type III secretion in Edwardsiella tarda virulence.
Edwardsiella tarda is a Gram-negative enteric bacterium affecting both animals and humans. Recently, a type III secretion system (TTSS) was found in Ed. tarda. Such systems are generally used by bacterial pathogens to deliver virulence factors into host cells to subvert normal cell functions. Genome-walking was performed from the eseB and esrB genes (homologues of Salmonella sseB and ssrB, resp...
متن کاملIntramacrophage Infection Reinforces the Virulence of Edwardsiella tarda.
UNLABELLED Edwardsiella tarda is an important pathogenic bacterium that can replicate in macrophages. However, how the intramacrophage infection process affects the virulence of this bacterium is essentially unknown. Here, we show that E. tarda replicates and induces a caspase-1-dependent cell pyroptosis in a murine macrophage model. Via pyroptosis, intracellular E. tarda escapes to the extrace...
متن کاملIntraspecific genetic variability of Edwardsiella tarda strains from cultured turbot.
Edwardsiella tarda is an enterobacterial fish pathogen that causes mortality in various fish species worldwide. In this study, we analyzed the intraspecific variability in a collection of E. tarda strains isolated from turbot. To do this we employed 4 polymerase chain reaction (PCR)-based methods: (1) random amplified polymorphic DNA (RAPD), (2) enterobacterial repetitive intergenic consensus-P...
متن کاملEdwardsiella tarda bacteremia with metastatic gastric cancer
Edwardsiella tarda (E. tarda) is a rare human pathogen; however, the overall mortality of bacteremia is reported to be up to 50%. Here, we describe a case of cholangitis with E. tarda bacteremia who had a pancreatoduodenectomy for a locally advanced gastric cancer. He was successfully treated using a cefmetazole, a second generation cephalosporin for 14 days. To the best of our knowledge, this ...
