From: Parasite-mediated interactions within the insect vector: Trypanosoma rangeli strategies
Illustration of Trypanosoma rangeli adhesion (A) and invasion (B) into the Rhodnius prolixus salivary gland. To cross the basal lamina (BL) that surrounds the salivary glands the parasite penetrates via the flagellum and invaginates in a vacuole (V) in which the trypanosome crosses the gland cells (GC) to reach the central lumen. After reaching the gland lumen, the parasite epimastigote long forms (ELF) remain adhered to the gland cell microvilli (GCM) by their flagella, while metacyclic trypomastigote forms (TF) are found swimming freely in the saliva. AG – accessory gland; ESF – epimastigote short forms.
