The Tacugama Sanctuary in Sierra Leone has been experiencing deaths of chimpanzees for over a decade with no explanation. Over a dozen chimpanzees have died due to an unexplained disease, and scientists believe it can affect humans. A newly discovered bacteria linked to this fatal illness in chimpanzees was reported for the first time in Nature Communications. The sanctuary staff has conducted several investigations to find out the cause of the infection but has reached no conclusions yet. Some of the antibiotics have proved to be better when tested on a chimp that recently started developing the syndrome. The syndrome can, however, still result in fatality.
