Morphology of various strains of the trypanosome causing disease in man in Nyasaland.—The wild-game strain

Trypanosomes of this species, isolated from five antelope, are here described and compared with the Human strains which formed the subject of a previous paper. The Wild-game strains were isolated by injecting blood of antelope into susceptible animals. The blood was, as a rule, injected into a healthy goat, monkey, and dog, and from these other animals were inoculated. Trypanosomes from the following species were studies: reedbuck, water-buck, oribi, and hartebeeste. In these experiments, with the exception of the oribi, the three inoculated animals became infected. In the case of the oribi the blood was inoculted into a monkey and dog, no goat being available, and the monkey alone took the disease.
