Veterinary bacteriology: information about important bacteria
|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|
|Type Strain:||ATCC 19264 = CCUG 47265 = NCTC 12159.|
||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-|
|Other Enzymes:||Tryptophanase - (= indole -), urease -|
|Biochemical Tests:||Citrate +, Voges-Proskauer +|
|Fermentation of carbohydrates:||
||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.|
|16S rRNA Seq.:|
||Two species have been described within the genus Listonella and they are closely related to species within the genera Vibrio and Aliivibrio.|
|New names of bacterial phyla|
The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota.Published 2023-03-01. Read more...
|The taxonomy of chlamydias|
Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBactPublished 2023-03-15. Read more...
