The organism marked by a red arrow in the photomicrograph above represents Trypanosoma gambiense.
Trypanosoma gambiense is a protozoan haemoflagellate endoparasite of man inhabiting the blood, lymph and the intercellular spaces of different tissues and organs of man. Hogs, goats, cattle and sheep are potential reservoir hosts.
The parasite causes a disease called Gambian or West-African sleeping sickness in human-beings. The disease African sleeping sickness was first described by Atkins in 1724 and Winterbottom in 1803, but the causative parasite was described in human blood by Forde in 1901 and later on named as T. gambiense by Dutton in 1903.
