Background: We report the causes of mortality for 4350 captive baboons that died or were euthanized due to natural causes during a 23 year period at the Southwest National Primate Research Center.
Methods: Necropsy records were retrieved and reviewed to determine a primary cause of death or indication for euthanasia. Data was evaluated for morphological diagnosis, organ system, and etiology.
Results: The 20 most common morphologic diagnoses accounted for 76% of the cases, including stillborn (10.8%); colitis (8.6%); hemorrhage (8.4%); ulcer (5.2%); seizures (4.7%); pneumonia (4.2%); inanition (4.1%); dermatitis (3.8%); spondylosis (3.3%); and amyloidosis (3.0%). The digestive system was most frequently involved (21.3%), followed by the urogenital (20.3%), cardiovascular (12.2%), and multisystem disease (10.3%). An etiology was not identified in approximately one-third of cases. The most common etiologies were trauma (14.8%), degenerative (9.5%), viral (8.7%), and neoplastic/proliferative (7.0%).
Conclusion: This information should be useful for individuals working with baboons.

Research shows mixed results about the impact of nursery rearing on baboons, with some studies indicating minimal differences in reproduction and behavior compared to mother-reared individuals.
A study with 231 olive baboons found that mother-reared baboons had different health indicators like higher heart rates, but overall health, body weight, and reproductive success were similar between nursery-reared and mother-reared groups.
The findings suggest that baboons may be less affected by abnormal rearing conditions compared to other nonhuman primate species, implying a degree of resilience in these animals.
Introduction: Inflammatory responses and coagulation disorders are a relevant challenge for successful cardiac xenotransplantation on its way to the clinic. To cope with this, an effective and clinically practicable anti-inflammatory and anti-coagulatory regimen is needed. The inflammatory and coagulatory response can be reduced by genetic engineering of the organ-source pigs.
Intraoral scanners are widely used in a clinical setting for orthodontic treatments and tooth restorations, and are also useful for assessing dental wear and pathology progression. In this study, we assess the utility of using an intraoral scanner and associated software for quantifying dental tissue loss in non-human primates. An upper and lower second molar for 31 captive hamadryas baboons () were assessed for dental tissue loss progression, giving a total sample of 62 teeth.
The study investigates hybridization among baboons to enhance our understanding of primate evolution, focusing on olive and yellow baboon species at the Southwest National Primate Research Center.
Researchers used full genome data from 881 baboons to analyze genetic ancestry and improve the quality of genetic markers, discovering historical admixture in some supposedly purebred specimens.
The findings included the creation of updated genetic maps and a set of 1,747 ancestry informative markers, which show strong agreement in global ancestry estimation but revealed phase switch errors influenced by the methods used.
