Light (left) and electron (right) microscopic examinations of schistosomules of Trichobilharzia szidati from the lungs and of T. regenti within the spinal cord from infected ducks. T. szidati schistosomules from/in lung (white arrow) with dark brown haem metabolites (white asterisk), crystals (white arrowheads) and/or lipid droplets (black arrowheads) in the gut lumen (black arrow). Detail of crystallization of hem metabolites is depicted in the box (a,b) T. regenti schistosomules (white arrow) migrating in the spinal cord with myelin (white asterisk) in the gut lumen (black arrows). Partially digested myelin sheath is depicted in detail in the box. (c,d) Immune cells surrounding (ic) or within the gut (black arrow, white asterisk) of T. regenti schistosomules (white arrow) in sub-meningeal space. Immune cells from sub-meningeal space are depicted in the box (e and f).
