enteric redmouth disease
Enteric redmouth disease, or simply redmouth disease is a bacterial infection of freshwater and marine fish caused by the pathogen ''Yersinia ruckeri''. It is primarily found in rainbow trout (''Oncorhynchus mykiss'') and other cultured salmonids. The disease is characterized by subcutaneous hemorrhaging of the mouth, fins, and eyes. It is most commonly seen in fish farms with poor water quality. Redmouth disease was first discovered in Idaho rainbow trout in the 1950s.〔(LSC - Fish Disease Leaflet 82 )〕 The disease does not infect humans.〔
==Distribution of disease==
Some fish species serve as vectors for the disease and have subsequently spread the pathogen to other parts of the world.〔 An example is the fathead minnow (''Pimephales promelas'') which is responsible for the spread of redmouth disease to trout in Europe. Other vectors include the goldfish (''Carassius auratus''), Atlantic and Pacific salmon (''Salmo salar''), the emerald shiner (''Notropis atherinoides''), and farmed whitefish (''Coregonus'' spp.). Infections have also occurred in farmed turbot (''Scophthalmus maximus''), seabass (''Dicentrarchus labrax''), and seabream (''Sparus auratus'').〔 It can now be found in North and South America, Africa, Asia, and Australia, as well as Europe.
