4. Discussion
Within the last decade it has become abundantly clear that African
great apes play a significant role in evolution, emergence, and
transmission of a range of infectious diseases important for human
populations. Simian immunodeficiency viruses and apicomplexan
parasites of the genus Plasmodium are among the best known examples
(Liu et al., 2010; Calvignac-Spencer et al., 2012; Liu et al.,
2014). Although the wild chimpanzees and other African great apes
live in regions endemic for African sleeping sickness, the research
on their trypanosome infections has been neglected. This situation
is mostly caused by the virtually insurmountable difficulties in
obtaining blood samples from free-ranging animals and ethical
unacceptability of experimental infections on captive animals.
