An amoeba associated with gill disease in turbot, Scophthalmus maximus (L.)
Abstract An amoeba associated with a severe gill disease affecting farmed turbot, characterized by pronounced hyperplasia of the branchial epithelia and accumulation of mucus between the secondary lamellae, is described for the first time. The amoeba was isolated, cloned and cultured on Bactoagar. L...
