Fig. 2From: Trypanosome infections in naturally infected horses and donkeys of three active sleeping sickness foci in the south of ChadElectrophoretic profiles illustrating DNA fragments resulting from the amplification of ITS1 of different trypanosome species. Lanes C−: negative controls; Lane TB+: positive control of purified DNA of T. b. gambiense isolate; Lane TC: positive control of purified DNA of T. congolense forest isolate; Lane M: molecular marker (GeneRuler1 kb DNA ladder); Lane 1: sample with trypanosomes of the subgenus Trypanozoon; Lanes 2, 6, 9, 10 and 11: samples T. congolense infections; Lane 7: sample with T. vivax; Lanes 3, 4, 5 and 8: samples with no trypanosome infectionBack to article page
