Comparison of direct and indirect methods of measuring arterial blood pressure in healthy male rhesus macaques (Macaca mulatta)

Blood pressure is a critical parameter for evaluating cardiovascular health, assessing effects of drugs and procedures, monitoring physiologic status during anesthesia, and making clinical decisions. The placement of an arterial catheter is the most direct and accurate method for measuring...

Physiologic correlates of interactions between adult male and immature long-tailed macaques (Macaca fascicularis)

Interactions between adult males and immature members of the same species are rare in most mammals; in contrast, an estimated 40% of primate species are characterized by an involvement of males in the social life of infants and juveniles. The...

Two methods of social separation for paired adolescent male rhesus macaques (Macaca mulatta)

Literature-based recommendations regarding how to separate pairs of laboratory-housed NHP when required for research, veterinary, or management needs are unavailable. This study assessed 2 separation techniques—rapid and stepwise—to determine whether a period of limited social access mitigates the behavioral stress...

Evaluation of a zinc gluconate neutralized with arginine product as a nonsurgical method for sterilization of rhesus macaques (Macaca mulatta)

Because rhesus macaques (Macaca mulatta) are prolific breeders, overpopulation can be problematic in both research and feral populations. Currently, the most effective contraceptive methods are hormonal control in female macaques and vasectomies in males. These methods each come with innate...

Effect of chronic social stress on prenatal transfer of antitetanus immunity in captive breeding rhesus macaques (Macaca mulatta)

Because tetanus can cause significant morbidity and mortality in NHP, colonywide vaccination with tetanus toxoid is recommended for outdoor breeding colonies of rhesus macaques, with primary immunizations commonly given to infants at 6 mo of age followed by booster vaccines...

Porches as enrichment for singly housed cynomolgus macaques (Macaca fascicularis)

Effective environmental enrichment is used by animals, promotes species-typical behavior, and decreases abnormal behavior. Porches attached to the front of an animal's cage provide additional space, perching opportunities, and a better view of the surroundings. Here we assessed the effectiveness...

Assessment of environmental enrichment for different primate species under low budget: A case study

The 2011 European Union Zoo Inquiry presented evidence that most zoos fail to achieve adequate levels of nonhuman animal welfare. Appropriate environmental enrichment (EE) can play a role in the promotion of welfare. However, financial and staff constraints frequently make...

Tailored enrichment strategies and stereotypic behavior in captive individually housed macaques (Macaca spp.)

The welfare of nonhuman animals in captivity is widely dependent on the natural psychological, physical, and behavioral needs of the animals and how adequately these needs are met. Inability to engage in natural behaviors can lead to chronic stress and...

Non-invasive detection and successful treatment of a Helicobacter pylori infection in a captive rhesus macaque

Gastritis is a commonly diagnosed condition in non-human primates used in biomedical research. As in humans, Helicobacter pylori infection may cause gastritis. The following report presents a method of non-invasive detection and a successful treatment protocol for this common pathogen.
