|Etymology:||Genus name: named after the American bacteriologist P. R. Edwards (1901-1966).|
Species epithet: slow (refers to the fact that it is biochemically inactive and can only ferment few carbohydrates).
|Significance:||More common in Asia than in the USA. Has been isolated from farmed and wild eel in Sweden.
[Of minor importance]
|Type Strain:||ATCC 15947 = CCUG 1638 = NCTC 10396.|
|Gram +/Gram -:||G-|
|Other Enzymes:||DNase -, esculinase -, ornithine decarboxylase +, tryptophanase + (cf. E. ictaluri), ureas -.|
|Biochemical Tests:||Citrate -, methyl red +, Voges-Proskauer -, hydrogen sulfide -.|
|Fermentation of carbohydrates:||
All strains ferment glucose under acid production and some of the strains also under gas production.
|Spec. Char.:||Can grow at 42°C (cf. E. ictaluri).|
|Disease:||Edwardsiellosis, septicemia in catfish and eels. "Red disease" of cultured eel.
|Virulence Factors:||Chondroitinase, quorum sensing and siderophore-mediated uptake of iron.|
|16S rRNA Seq.:|
||Four species have been described within the genus Edwardsiella. These bacteria belong to the familyEnterobacteriaceae and they are relatively closely related to bacteria within the genera Morganella and Proteus.|
