|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:||
|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.|
|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
