Non-human primates with a close phylogenetic relationship to humans are often susceptible to a number of diseases and parasites found in humans (Tauraso et al., 1969) . To establish an unknown pathogen as the cause of a disease Koch's postulates should be followed (Fouchier et al., 2003; Pan and Sun, 2004; Conly and Johnston, 2008) . The similarity of genetic, physiological, and behavioral characteristics between humans and non-human primates, and the occurrence of similar pathological changes upon infection, have led to non-human primates becoming an irreplaceable animal model for the study of pathogen infection, the screening of anti-pathogen drugs, and vaccine evaluation (Conly and Johnston, 2008) . Because of the critical role that non-human primates play in the study of these pathogens, it is critical to find safe and reliable methods for their physical containment.
