monkeys are important experimental models for investigating human diseases. the aim of this study was to survey the alimentary tract parasites among imported vervet monkeys (cercopithecus aethiops) to iran. fecal samples were collected from 40 vervets imported from tanzania to razi vaccine and serum research institute of iran. fecal samples were assessed by direct smear and telman sedimentation...

The results of an international comparative study of the neurovirulence of oral poliomyelitis vaccines in three species of Old World Monkeys, viz. Macacus irus (cynomolgus), M. mulalla (rhesus) and Cercopithecus aelhiops (vervet) are pre3ented. The greate~t sensitivity to Sabin poliovaccine types 1 and IIr was shown by cynomolgus monkeys, followed by rhesus and vervet monkeys, whilst vervet mon...

Abstract Generally, urbanisation affects biodiversity negatively; however, some species thrive in urban areas. One mammalian thriving the forest mosaic landscape is vervet monkey ( Chlorocebus pygerythrus ), particularly Durban, eThekwini Municipality, KwaZulu-Natal Province, South Africa. Vervet monkeys’ spatial use can provide important ecological information to understand their behavioural p...

In Kenya, Leishmania major is responsible for human cutaneous leishmaniasis (CL). Natural infection with L. major of a vervet monkey and experimental susceptibility of some nonhuman primates (NHPs) from Kenya has been established. However, there has been no comprehensive study of the prevalence of zoonotic CL in Kenya. And also, no investigation has been done to assess whether NHPs could be pot...

Rhesus and vervet monkeys respond differently to treatment with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride neurotoxin (MPTP). Both species develop akinesia, rigidity, and severe postural instability. However, rhesus monkeys only develop infrequent, short episodes of high-frequency tremor, whereas vervet monkeys have many prolonged episodes of low-frequency tremor. After MPTP tre...

BACKGROUND There are three subspecies of Trypanosoma brucei: T. b. gambiense, T. b. rhodesiense and T. b. brucei. The first two are infectious to humans, whilst T. b. brucei is not. Identifying an animal model of T. b. brucei that mimics human African trypanosomiasis (HAT) would enable researchers to study HAT without subjecting themselves to undue risks such as accidental infection. OBJECTIV...

In Amboseli National Park, Kenya, both superb starlings, Spreo superbus, and vervet monkeys, Cercopithecus aethiops, give acoustically different alarm calls to different classes of predators. The 'raptor alarms' of starlings and vervet monkeys are so called because they are given exclusively to avian species that attack from the air. In contrast, while vervets give 'leopard alarms' to a narrow ...

The alarm calls of vervet monkeys (Chlorocebus pygerythrus) constitute the classic textbook example of semantic communication in nonhuman animals, as vervet monkeys give acoustically distinct calls to different predators and these calls elicit appropriate responses in conspecifics. They also give similar sounding calls in aggressive contexts, however. Despite the central role the vervet alarm c...
