Flavobacterium hydatis is a type of bacteria . The species is a cause of bacterial gill disease in salmon .

features

The species Flavobacterium hydatis is Gram-negative . The cells are rod-shaped. The width is between 0.4 and 0.7 µm, the length between 1.5 and 15.0 µm. There are also coccoid forms and filaments. There are no flagella . However, Flavobacterium hydatis can move in a gliding motility . This type of movement can be found in many representatives of the genus. Growth takes place at temperatures between 5 and 35 ° C. 20-25 ° C are optimal. The species is facultatively anaerobic, so it shows when certain nutrients are added, such as B. peptone , even without oxygen growth. Sphaeroplasts can occur in older cultures . The GC content in the DNA is 32.7%.

Systematics

Flavobacterium hydatis one of the family of Flavobacteriaceae , which in turn to the class bacteroidetes is provided.

etymology

The genus name Flavobacterium is based on the Latin word "Bacterium" (bacterium) and the Latin word "flavus", which means yellow. The latter refers to the colors of the colonies, which often show a pronounced yellow. The species name is based on the Latin word hydatis , which means something like "on / from water".

Veterinary medicine

Flavobacterium hydatis is pathogenic for salmon , it is the cause of bacterial gill disease . In the genus Flavobacterium , several bacteria are pathogenic for fish, examples are F. columnare , F. johnsoniae and F. psychrophilum .
