Facility of outflow in the eye of the vervet monkey Cercopithecus ethiops was studied by constant-rate and by constant-pressure infusion. Facility increased greatly after the injection of 2 to 3 fig of pilocarpine into the anterior chamber or after the application of 0.2 to 0.3 ing. to the cornea. The effect on facility consisted of 2 components. One component was reversed in 3 to 5 minutes by ...

The playback experiment – the playing back of recorded animal sounds to the animals in order to observe their responses – has twice become central to celebrated researches on non-human primates. First, in the years around 1890, Richard Garner, an amateur scientist and evolutionary enthusiast, used the new wax cylinder phonograph to record and reproduce monkey utterances with the aim of translat...

Abstract The urban landscape is a complex mosaic of costs and benefits for wildlife. Although many species may adapt thrive in the mosaic, complexity this can be stressful have health implications wildlife, raising concerns zoonosis biodiversity. In study, we assessed how human–primate interactions influenced parasite risk anxiety-related behaviour vervet monkeys KwaZulu-Natal, South Africa. Ov...

The current in vivo models for the utility and discovery of new potential anti-leishmanial drugs targeting Cutaneous Leishmaniasis (CL) differ vastly in their immunological responses to the disease and clinical presentation of symptoms. Animal models that show similarities to the human form of CL after infection with Leishmania should be more representative as to the effect of the parasite with...
