Comparative histopathology of mucosa associated lymphoid tissue in the gills of Atlantic salmon Salmo salar and southern bluefin tuna Thunnus maccoyii ...
The recent identification of an interbranchial lymphoid tissue (ILT) revealed that an organized mucosa-associated lymphoid tissue (MALT) was present in the gills of salmonids. Due to its location in the gills, and lymphoid nature, it was hypothesized that the ILT could be affected by amoebic gill di...
