Comparison between bloodstream and procyclic form trypanosomes for serological diagnosis of African human trypanosomiasis.
Trypanosoma brucei brucei MiTat 1.2 bloodstream and corresponding procyclic forms, as well as procyclics of T. b. gambiense and T. b. rhodesiense, were fixed, in suspension, using a mixture of 80% acetone and 0.25% (v/v) formalin in saline and used as antigens for diagnosis of African human trypanosomiasis by the indirect immunofluorescent antibody test. T. b. brucei bloodstream forms detected 41/42 and 37/41 parasitologically diagnosed cases of T. b. rhodesiense and T. b. gambiense trypanosomiasis, respectively, while the procyclic stages detected the same number (41/42) of T. b. rhodesiense, but fewer (29/41) T. b. gambiense infections.
