Occurrence of the microsporidian parasite Nucleospora salmonis in four species of salmonids from the Massif Central of France
International audience Nucleospora salmonis (Hedrick, Groff et Baxa, 1991), an intranuclear microsporidian parasite of marine and freshwater fish, causes diseases mainly in salmonid species. Losses have been reported in stocks of salmonid fish reared in the region of Auvergne (France). The cause of...
