also known as: Hole in the Head Disease
|
Edwardsiella ictaluri is a bacterium that causes Enteric Septicaemia of Catfish (ESC) disease. It is known also as Hole in the Head disease. Its pathology is such that it causes chronic encephalitis or acute septicemias. In aquaculture, its hosts include white, channel, walking and sutchi catfish species. In several cases rainbow trout and chinook salmon have been shown to become infected under experimental conditions. Its wild hosts include the Japanese ell, tadpole madtom, glass knifefish, rosy barb, Devario devario (carp), white, bullhead, blue and wels catfish. It is a bacterium present commonly in the environment. As the first symptom of infection is weight loss due to anorexia, fish can be treated only after the infection has been recognized. This pathogen does not infect humans. |
