We are grateful to Ayalew Mergia for providing the pSFV-1Lgp plasmid. This research was approved by the University of New Mexico’s Human Research and Review Committee and Institutional Animal Care and Use Committee. It was supported in part by grants from the Chicago Zoological Society, Unconventional Concepts, Inc., the University of New Mexico’s Student Research and Allocations Committee, the University of New Mexico School of Graduate Studies, NIH/NCRR grant P51 RR00166 (L.J.E) and NIH grant P51 RR013986-06 (J.S.A.). Dr. Jones-Engel is a research scientist at the University of Washington’s National Primate Research Center. Her research focuses on bidirectional pathogen transmission between humans and primates in Asia and its implications for public health and primate conservation. References 1.
