Trophozoites from the HGINV isolate with a normal ultrastructure found in a 30-day-old gerbil.
Abundant glycogen granules and ribosomes showed a characteristic electron-dense appearance. The parasites were integrated into the connective tissue of the submucosa. Extensions of the fibroblast membranes (*) and an intact basal membrane (arrowheads) were observed surrounding the trophozoites. Vacuoles (V); endoplasmic reticulum (thin arrows); mitochondria (M), electron-dense granules (arrows); collagen fibres (CF); adhesive disk (AD); flagella cut in various planes (F), axonemes (AX); cell nucleus (N). 20000x.
