Viral seroprevalence in northern pig-tailed macaques (Macaca leonina) derived from Ho Chi Minh City, Vietnam

Abstract

Non-human primates are natural virus reservoirs, whether wild or domestic. In this study, we determined the seroprevalence of common viruses by ELISA in a northern pig-tailed macaque (Macaca leonina) colony derived from Ho Chi Minh City, Vietnam. A total of 20 types of virus which are commonly selected as target microorganisms for specific-pathogen-free colonies, or which have zoonotic potential were included in this study. The results showed only 2 in 90 northern pig-tailed macaques were seronegative for all the detected viruses, and at least 16 out of the total 20 types of virus tested were prevalent in this colony, so these macaques were commonly infected by various viruses. These macaques should be carefully assessed for viral seroprevalence in order to prevent zoonotic diseases from being transferred to human beings.
