Genetic Characterization of a Captive Colony of Pigtailed Macaques (Macaca nemestrina)

摘要

Effective colony management is critical to guarantee the availability of captive NHP as subjects for biomedical research. Pigtailed macaques (Macaca nemestrina) are an important model for the study of human and nonhuman primate diseases and behavior. Johns Hopkins University hosts one of the largest captive colonies of pigtailed macaques in the United States. In this study, we used 56 single-nucleotide polymorphisms (SNP) to characterize this population of pigtailed macaques, understand their population structure, and assess the effectiveness of their colony management. The results demonstrate that the colony has maintained a high level of genetic diversity, with no loss of heterozygosity since its origin, and low levels of inbreeding and genetic subdivision.
