Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.

In 2008, the sample was tested by researchers, identifying partial HIV viral sequences. [8] The specimen, named DRC60 contained a strain of HIV-1 around 88% similar to LEO70, but was found to be most closely related to HIV-1 (M) subgroup A isolates. These two specimens are significant not only because they are the oldest known specimens of HIV ...
