GAME ANIMALS TO DISEASE IN AFRICA 
9 
buck, a water-buck, a hartebeest, and a wart-hog were found 
to contain trypanosomes. One of these animals was much 
emaciated, it is not stated which, but it is a point of consider- 
able interest if the ill-health was due to the presence of try- 
panosomes in its blood, particularly in view of the fact that the 
antelope artificially infected with T. gambiense by the Sleeping 
Sickness Commission in Uganda remained apparently in perfect 
health for a year afterwards. Dr. Wolf el injected blood 
from 10 of the above 40 animals into dogs ; and cultures 
in both were attempted from the blood of 6 others. The 
dogs did not sicken and no trypanosomes were found in the 
broth. 
It is worthy of note that of the above 40 wild animals 
all are game animals except 9, which only include 8 
species. 
In German East Africa also Professor F. K. Kleine and 
0. W. Fischer examined 54 wild animals, including hartebeest, 
topi ( Damaliscus corrigum ), water-buck, bush-buck, reed-buck, 
and wild pigs. Of these, 7 hartebeest, 2 water-buck, 1 bush- 
buck, and 1 pig (total 11) showed trypanosomes (‘ Sleeping 
Sickness Bulletin,’ No. 31, p. 406). It will be noticed that 
of these 54 wild animals all are game animals, except the 4 
pigs. No small animals, such as rodents, apparently were 
examined. 
The above conclusions have been arrived at as the result 
of experiments, particularly the experiments of the Sleeping 
Sickness Commission in Uganda 1908-10, which were most 
carefully devised and carried out ; but in examining the con- 
clusions arrived at, there are three very important points which 
are apparent : — 
(i) Attention has been almost entirely concentrated upon 
game animals. 
(ii) Up to the present no wild animal has been found 
naturally infected with a trypanosome of sleeping 
sickness, except two monkeys, one found by the 
Sleeping Sickness Commission in Uganda 1908-10, 
and the other by Koch, Beck and Kleine’s Commission. 
It was caught on Sesse Island (‘ Sleeping Sickness 
Bulletin,’ No. 82, p. 444).
