Mihok, S., Otieno, L.H. & Darji, N. (1989) Isoenzyme polymorphism and the blood incubation infectivity test (BIIT): Contradictory predictions of human infectivity for Trypanosoma brucei. pp. 137-141 in ISCTRC. (Ed) Nairobi, International Scientific Council for Trypanosomiasis Research and Control.

Isoenzyme information of Trypanosoma brucei isolates from the Lambwe Valley, Kenya was used to differentiate between human-infective isolates and isolates of unknown infectivity. Human infectivity was linked to specific banding patterns for the enzymes isocitrate dehydrogenase, peptidase one, aspartate aminotransferase, and alanine aminotransferase. No relationship was found between BIIT results and isoenzyme patterns. These contradictory results probably reflect the unreliability of BIIT information in determining human infectivity.
