In 2008, a preemptory study was conducted to determine the effectiveness of saliva testing in mountain gorillas. During this study, discarded forage food was collected from free-ranging mountain gorillas and salivary alpha-amylase and gorilla DNA was consistently recovered. Additionally, dental ropes were given to the confiscated orphans in Kinigi. After the gorillas chewed on the rope, an average of 200 ul of saliva was collected off of each dental rope and they were able to successfully detect gorilla DNA in those samples. A study was then conducted at UC Davis on 23 rhesus macaques to determine the effectiveness of saliva sampling, where dental ropes were compared with oral swab samples. Then, forage food techniques in captive western lowland gorillas were tested. Next, a similar technique was implemented in a free ranging population of 22 baboons. Childrens oral swabs were hidden in a banana and given to each baboon. The baboons would then eat the banana and spit out the swab. An average of 800 ul of saliva was collected from these swabs - more than enough to test. Only the discarded forage food technique will be applicable to free-ranging mountain gorillas however, though improving sampling of other primate species through the distribution of dental ropes and children’s swabs could help better describe the epidemiology of certain viruses in the region.
