Changes in the innate response of Atlantic salmon, Salmo salar L., exposed to experimental infection with Neoparamoeba sp
An experiment was conducted to determine the effect of Neoparamoeba sp. infection on the innate immune responses of Atlantic salmon. Atlantic salmon were experimentally infected with Neoparamoeba sp. and serially sampled 0, 1, 4, 6, 8 and 11 days post-exposure (dpe). Histological analysis of infecte...
