Specific Organism 507 Specific Organism.—The discovery of the specific organisms was foreshadowed byNepveu,* who recorded the existence of try- panosomes in the blood of several patients coming from Algeria, by Barron,t and by In 1901 Forde received under his care at the hospital in Bathurst (Gambia), a European, the captain of a steamer on the River Gambia, who had navigated the river for six years, and who had suffered several attacks of fever that were looked upon as malarial. The examination of his blood revealed the presence not of malarial parasites, but of small worm-like bodies, concerning the nature of which Forde was undecided. § Later, Button, in conjunction with Forde, examined this patient, whose condition had become more serious, and recognized that the worm- like bodies seen by Forde were trypanosomes. Of these parasites he has written an excellent description, calhng them Trypanosoma. Fig. 206.—Trypanosoma gambiense (Todd). The patient thus studied by Forde and Button died in England January i, 1903. In 1903 Button and Todd* * examined 1000 persons in Gambia and found similar trypanosomes in the bloods of 6 natives and i quadroon. In the same year Mansonft discovered 2 cases of trypanosomiasis in Europeans that had be- come infected upon the Congo. BrumptJJ also observed T. gam- biense at Bounba at the junction of the Ruby and the Congo, and Baker§§ observed 3 cases at Entebbe in Uganda. During all this time no connection was suspected between these * "Memoirs,.Soc. de Biol, de Paris," 1891, p. 49. t "Transactions of the Liverpool Medical Institute," Dec. 6, 1894. t "Janus," July to August, 1898, p. 41. § "Trypanosomes and Trjrpanosomiasis," Laveran and Mesnil, 1907.
