Cytomegalovirus (CMV) is a common chronic herpesvirus found in humans and numerous other mammalian species. In people, chronic viruses like CMV can alter overall health and immunity and pose a serious risk for those with an inadequate immune system. In addition, CMV plays an important role in animal health, and could affect the health of vulnerable populations, like endangered species. Previous studies found a high rate of CMV seropositivity among adult baboons (), and results from our laboratory revealed that baboon CMV (BaCMV) seropositivity was correlated with altered immune cell populations. In the current study, we further characterized BaCMV infection in normal, adult baboons. Analysis of blood samples from baboons (age, 6 to 26 y) revealed a low overall prevalence of detectable of BaCMV DNA, with a higher detection rate in aged baboons (older than 15 y). Furthermore, data suggest that individual baboons maintain similar rates of recurrence and levels of BaCMV shedding in saliva over time. Finally, we evaluated multiple commercially available assays for antihuman CMV IgG and IgM for use with baboon sera. Results of this study will improve our understanding of BaCMV and may be directly relevant to other closely related species.

A comparative study of causal perception in Guinea baboons (Papio papio) and human adults.

In humans, simple 2D visual displays of launching events ("Michottean launches") can evoke the impression of causality. Direct launching events are regarded as causal, but similar events with a temporal and/or spatial gap between the movements of the two objects, as non-causal. This ability to distinguish between causal and non-causal events is perceptual in nature and develops early and preverbally in infancy.

Introduction: Schistosomiasis is a neglected tropical disease that puts over 200 million people at risk, and prevention options are sparse with no approved vaccine. Our vaccine candidate, SchistoShield, is based on an approximately 87 kDa large subunit of calcium activated neutral protease - termed Sm-p80 - combined with a potent TLR4 agonist-based adjuvant. SchistoShield has been shown to prevent disease throughout the parasitic life cycle - including egg, juvenile, and adult worm stages - in numerous animal models up to and including baboons.

Article Synopsis
- Neutrophil to lymphocyte ratio (NLR) serves as a marker for stress and inflammation, but its research in nonhuman primates (NHPs) like baboons is limited, with some links to health and longevity noted.
- In this study, researchers monitored baboon NLR over time, noting that younger baboons showed increasing NLR, especially females, while older ones remained stable.
- Findings suggest that the order of sedation impacts NLR—those sedated later had higher levels—while higher monthly sedation rates corresponded with lower NLRs, highlighting NLR's potential as a stress welfare indicator in clinical settings.
High early lactational synchrony within baboon groups predicts increased infant mortality.

Article Synopsis
- Social group composition influences fitness in female baboons, especially during critical periods like early lactation when competition for resources peaks among mothers with infants.
- The study revealed that as more females in a group had young infants, female-female aggression increased, leading to higher infant mortality rates.
- Findings suggest that both aggressive interactions among mothers and potential infanticide by younger females can discourage synchronous birthing, impacting reproductive behaviors in this species.
Age- and size-related changes in hind limb muscles in two baboon species (Papio anubis and P. papio).

Article Synopsis
- Body size significantly influences biological functions, including locomotion, which is essential for understanding competitive dynamics, especially among juvenile animals.
- This study examines the growth of hind limb muscles in two baboon species (olive baboons and Guinea baboons) to assess size and age-related changes in their locomotor systems.
- Results indicate that while there are no sexual differences in growth patterns, the olive baboon exhibits isometric scaling of muscle mass, while the Guinea baboon shows allometric scaling, which may relate to differences in adult body size and locomotor independence.
