The structure of Podocotyle atomon metacercariae cysts and their surrounding capsules in the second intermediate hosts Locustogammarus locustoides (Brandt, 1851) and Spinulogammarus ochotensis (Brandt, 1851) was assessed using light and transmission electron microscopy. A single, amorphous layer represents the cyst formed by the parasite. The capsules formed by the host consist of two layers: an electron-light, loose inner layer, and an electron-dark, unstructured outer layer, including a small amount of intact and fragmented host cells. The inner capsule layer may have been formed by the degeneration and transformation of the muscle tissue of amphipods surrounding the larva. The outer layer of the capsule contained deposits of pigment. [ABSTRACT FROM AUTHOR] |
