. Severe glomerular changes in the kidney of rainbow trout suffering from presumptive chronic viral haemorrhagic septicaemia are described. The pathological changes, as revealed by light‐ and electron microscopy, resembled those of membranous glomerulonephritis in mammals. Large electron‐dense subendothelial‐mesangial deposits were present in most glomeruli. A lattice‐like arrangement of macromolecules was observed. Monocytes and macrophages were observed in the capillary convolute. The possibility of post‐infectious disease nephropathy with aggregation of immunocomplexes in the capillary wall in fishes is discussed.
