Background: To unravel the causes of major depressive disorder (MDD), the third leading cause of disease burden around the world, ethological animal models have recently been proposed. Our previous studies highlighted a depressive-like profile among...
Assessing the cardiovascular safety of new chemical or biological entities is important during pre-clinical development. Electrocardiogram (ECG) assessments in non-human primate (NHP) toxicology studies are often made using non-invasive telemetry systems. We investigated whether ECG...
Reduced space can lead to crowding in social animals. Crowding increases the risk of agonistic interactions that, in turn, may require additional physiological defensive coping mechanisms affecting health. To determine the stress induced from increased...
Positive reinforcement training can be used in many ways to enhance the welfare of captive primates. Training for biologic sample collection is one application of positive reinforcement training. In this study, 35 adult female chimpanzees...
In modern zoos, training should be an integral component of the animal care and management. The benefits of training include the opportunity for positive interactions with caretakers. This study was carried out with a group...
When training animals, time is sometimes a limiting factor hampering the use of positive reinforcement training (PRT) exclusively. The aim of this study was to evaluate the effects of a combination of negative and positive...
The exchange of services such as allo-grooming, allo-preening, food tolerance and agonistic support has been observed in a range of species. Two proximate mechanisms have been proposed to explain the exchanges of services in animals...
Due to the despotic nature of rhesus macaques (Macaca mulatta) and their frequent use in biomedical research, it is important to understand the impact that standard housing practices can have on individuals of this species...
The common marmoset (Callithrix jacchus) is a New World primate that is a useful model for medical studies. In this study, we report a convenient, reliable, and noninvasive procedure to genotype a living common marmoset...
The common marmoset (Callithrix jacchus, C. j.) is an established primate model in biomedical research and for human-related diseases. Monitoring of cardiovascular parameters including blood pressure (BP) is important for the health surveillance of these...
