| 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: | 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. | ||||||||
| Gram +/Gram -: | G- | ||||||||
| Metabolism: | Facultatively anaerobic | ||||||||
| Catalase/Oxidase: | +/+ | ||||||||
| Other Enzymes: | Tryptophanase - (= indole -), urease - | ||||||||
| Biochemical Tests: | Citrate +, Voges-Proskauer + | ||||||||
| Fermentation of carbohydrates: | D-glucose + lactose - maltose + L-rhamnose ? sucrose + L-arabinose ? cellobiose ? D-mannitol + salicin - trehalose + glycerol + inulin ? raffinose ? D-sorbitol + starch ? |
||||||||
| Spec. Char.: | Halophilic | ||||||||
| Special Media:
| 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. | ||||||||
