BACKGROUND Edwardsiella tarda is the etiologic agent of edwardsiellosis, a devastating fish disease prevailing in worldwide aquaculture industries. Here we describe the complete genome of E. tarda, EIB202, a highly virulent and multi-drug resistant isolate in China. METHODOLOGY/PRINCIPAL FINDINGS E. tarda EIB202 possesses a single chromosome of 3,760,463 base pairs containing 3,486 predicted ...

Outer membrane protein C of Edwardsiella tarda is a major cell surface antigen and it was identified to be an immunogenic protein by Western blot using flounder (Paralichthys olivaceus) anti-recombinant OmpC (rOmpC), and anti-E. tarda antibodies. rOmpC tested the immune protective effect against E. tarda challenge in a flounder model and produced a relative percentage of survival rate of 85%. T...

Edwardsiella tarda is the pathogen responsible for edwardsiellosis, a serious infectious disease of freshwater and marine fish species, and currently recognized to be the species pathogenic for human. An anti-idiotypic monoclonal antibody (mAb), 1E11, has been developed. It mimics the protective epitope of E. tarda and can prevent fish from infection of E. tarda. In this study, the correct vari...

Antibacterial activity of crude extracts of culinary spices like Aniseed (Pimpinella anisum), Star anise (Illicum verum Hook fruit) and Cinnamon (Cinnamomum zeylanicum) against some of the common fish bacterial pathogens like Aeromonas hydrophila, Aeromonas salmonicida and Edwardsiella tarda were explored by finding minimum inhibitory concentration (MIC). A twofold serial dilution of compounds ...

The increase in koi fish cultivation can lead to risks and caused problems. main problem is high disease attacks by the bacteria Edwardsiella tarda. One of alternatives control immunostimulant treatment with use maggot, Hermetia illucens Larvae, known as Black Soldier Fly (BSF). This study aims report effect maggot a substitute for feed formulations on immune system infected E. used descriptive...

The protective effects of a subunit vaccine, recombinant protein Edwardsiella tarda glyceraldehyde 3-phosphate dehydrogenase (Rec) combined with peptidoglycan (PGN) and polyinosinic:polycytidylic acid (polyIC), against edwardsiellosis in Japanese flounder Paralichthys olivaceus were investigated to evaluate an adjuvant property pathogen-associated molecular patterns. ?By injection the mixture p...

The current study evaluated the effects of a methanol extract from Chaetomorpha aerea (a green alga) on non-specific immune responses and resistance against Edwardsiella tarda infection in Labeo rohita. Different doses (5, 50 500 mg/kg body weight) were injected into fish intraperitoneally while control group was with 0.2 mL sterile physiological salt solution. Variations several immunostimulat...
