Primates are frequently used today in dental research and in South Africa the primate most commonly used is the vervet monkey (Cercopithecus pygerythus). This paper describes the normal histology of the soft palate in this animal based on a preliminary study towards the possible use of the vervet monkey in cleft palate research. Materials and methods Twenty-five soft palates from adult vervet m...

The relationship between humans and non-human primates in South Africa is problematic. On the one hand, vervet monkeys were formerly designated vermin species and could be destroyed at will. On the other hand, many people keep young vervets as pets even though this is illegal, and the animals are confiscated if discovered. Sanctuaries were established to accommodate large numbers of orphaned an...

Nine vervet monkeys (Cercopithecus aethiops) were infected intradermally with 8 x 10(7) virulent L. donovani promastigotes. Four animals developed clinical visceral leishmaniasis and died over a period of 18 months. The remaining five animals have remained asymptomatic for a period of 3 years now. Attempts to isolate parasites from spleen and liver through biopsies were fruitless. Immunological...

Globally, habitat degradation is accelerating, especially in the tropics. Changes to interface habitats can increase environmental overlap among nonhuman primates, people, and domestic animals and change stress levels in wildlife, leading to changes in their risk of parasite infections. However, the direction and consequences of these changes are unclear, since animals may benefit by exploiting...

Free-ranging vervet monkeys can solve a complex, multi-player coordination problem, learning to remain outside a 'forbidden circle' imposed by one member of the troop, in the absence of any social learning, communication, or policing by more dominant animals.

BACKGROUND Tools for authenticating cell lines are critical for quality control in cell-based biological experiments. Currently there are methods to authenticate human cell lines using short tandem repeat (STR) markers based on the technology and procedures successfully used in the forensic community for human identification, but there are no STR based methods for authenticating nonhuman cell l...

The physical growth patterns of crested langurs and vervet monkeys are investigated for several unilinear dimensions. Long bone lengths, trunk height, foot length, epiphyseal fusion of the long bones and the pelvis, and cranial capacity are compared through six dental growth stages in male Trachypithecus cristatus (crested langurs) and Cercopithecus aethiops (vervet monkeys). Results show that ...
