Wildlife trade is a multibillion dollar global industry that impacts conservation, biodiversity and health. Millions of wild animals are collected and legally or illegally traded annually.2 Approximately 75% of emerging infectious diseases are zoonotic3, and the majority originate from wildlife1. Hence, handling and trade of wildlife are important factors in the emergence and spread of infectious diseases. However, little is known about species or repertoire of pathogens moved through the bushmeat trade. In this presentation we will discuss current molecular assays and their implementation in a program focused on surveillance of bushmeat confiscated at several US ports of entry. ‘DNA barcoding’ results identified bushmeat sample origin from nonhuman primates, including guenon (Cercopithecus sp.) and mangabey (Cercocebus sp.), bats, such as the greater long-tongued fruit bat (Macroglossus sobrinus), and cane rat (Thryonomys sp.). The application of family-level virus screening, also known as consensus PCR, of bushmeat from non-human primates revealed multiple strains of simian foamy virus and primate herpesviruses from two genera. Our results demonstrate the applicability of molecular diagnostic testing for species and pathogen identification in wildlife trade products. These results further help define animal species and pathogens present in the global wildlife trade and will be important in informing discussions and implementing strategies to protect public health as well as the conservation of animal species.
