A, D – liver flukes of Parafasciolopsis fasciolaemorpha, 10× (eyepiece) and 4× (objective); B, E – cyst capsule, 10× (eyepiece) and 4× (objective); C, F – the inner part of the cyst capsule, 10× (eyepiece) and 10× (objective); G – bile ductules in the layer of infiltration and secondary fibrosis, 10× (eyepiece) and 40× (objective); H – arteries in the layer of secondary fibrosis, 10× (eyepiece) and 40× (objective); I – cells of inflammatory infiltration, 10× (eyepiece) and 100× (objective). A, B, C, G, H, I – HE staining; D, E, F – Van Gieson staining. Black arrow – bile ductule, white arrow – artery, double arrow – connective tissue hyperplasia, * inflammatory infiltration
