Abstract
The simian foamy virus (SFV) has been reported to be transmissible among humans occupationally exposed to nonhuman primates. Nevertheless, epidemiological and genotypic data on the SFV in Macaca mulatta and zookeepers in China are limited. In the present study, SFV proviral DNA was detected in 74 blood samples from M. mulatta and 12 saliva specimens from zookeepers by nested polymerase chain reaction. A total of 29 blood samples from M. mulatta (29/74, 39.19%) and two saliva specimens from zookeepers (2/12, 16.67%) were positive. The phylogenetic analysis indicated that these SFV strains shared the highest homology with Macaca fascicularis (93.4%). The two SFV strains infected human beings, and shared the highest homology of 98.6% with each other as well as 90.8-99.5% with M. mulatta. The investigation revealed the high prevalence of the SFV in M. mulatta in China and its zoonotic transmission to humans.
