Atlantic salmon (Salmo salar L.) exposed to cultured gill-derived Neoparamoeba branchiphila fail to develop amoebic gill disease (AGD)

Gill-derived Neoparamoeba spp. from Atlantic salmon cause amoebic gill disease (AGD) in naive recipients. Atlantic salmon were inoculated with clonal gill-derived Neoparamoeba branchiphila that had been cultured in the presence or absence of Atlantic salmon cutaneous mucus. Neoparamoeba branchiphila did not elicit AGD and the supplementation of cultures with cutaneous mucus did not influence virulence. Amoebic gill disease (AGD) of Atlantic salmon is caused by amphizoic marine amoebae, Neoparamoeba spp. (Adams & Nowak, 2004; Dykova, et al., 2005). In
