T brucei rhodesiense?

Trypanosoma brucei by morphology and I would guess rhodesiense by geographic location.

T. brucei, I do not think the 2 species can be differentiated by morphology.

Oppps the questions says East Africa, so that would go more with T. brucei rhodisiense. My bad.

Bobbi, Is there a line of demarcation between the 2 subspecies, or is there some ov erlap? T.brucei by the way.

Fred P - I recall seeing a map of the distribution of rhodesiense and gambiense and that there is no overlap, but I just checked the CDC website to be sure:

"At present, there is no overlap in their geographic distribution."
