Abstract (summary)

Loma salmonae is a microsporidian parasite pre-dominately infecting the endothelial cells of Pacificsalmon, Oncorhynchus spp. Loma salmonae formshypertrophied cells (xenomas) which are oftenvisible as white cysts in the gills. The parasite hasbeen associated with significant mortalities inspawning wild stocks (M. Higgins, personal com-munication), hatcheries (Hauck 1984) and inmarine netpen farms in the Pacific North-west(Kent, Elliott, Groff & Hedrick 1989; Speare,Brackett & Ferguson 1989; Shaw & Kent 1999).
