Species/Subspecies: Listonella anguillarum
Categories: Causes hemolysis; motile
Etymology: Genus name: named after Dr. J. Liston (?).
Species epithet: of eels.
Significance:  [Of minor importance]   
Alternative Species Name(s):Vibrio anguillarum
Taxonomy:
Phylum
Proteobacteria
Class
Gammaproteobacteria
Order
Vibrionales
Family
Vibrionaceae 
Genus
Listonella
Type Strain: ATCC 19264 = CCUG 47265 = NCTC 12159.
Macromorphology (smell):
     
Small translucent colonies (1-2 mm in diameter after 24 h). Hemolysis kan be observed around individual kolonies after 24 h and after 48 h massive hemolysis has occured where the colonies are close together (see Fig. 85:3).
Micromorphology: Small (0.5-0.8 x 1.4-2.6 µm) motile and curved rods (comma-shaped). The bacterium has one polar flagellum. Thus, the bacterium is monotrichous.

Special Media:
Listonella anguillarum  
V. anguillarum is growing well on purple agar, but this strain does not ferment lactose.
Disease:Vibriosis or red pest of eels.
Hosts: Salmonid fish, eel
Clinical Picture: Wounds in the skinn, septicemia, spleenomegaly.
