Analyzing pace frequencies in bipedal primates and primate "predecessors" reveals mechanisms that regulate foot inversion and thus ensure foot stability at touchdown Hasselt University
In walking bipedally, various arboreal New World primate species use a “forefoot first” strategy, after which heel contact occurs. A similar walking scenario is seen in arboreal New World marsupials like the opossum, a quadrupedal primate “predecessor”. In opossum walking the swing phase ends with the foot in the inverted position to the next touchdown with the forefoot. We therefore hypothesized that those quadrupedal marsupials which are ...
Reproductive research in non-human primates at Institute of Primate Research in Nairobi, Kenya (WHO Collaborating Center): a platform for the development of clinical infertility services? KU Leuven
The Institute of Primate Research (IPR; www.ipr.or.ke) is a WHO collaborating center for research in reproductive biology, infectious diseases and ecology/conservation. It includes a fully equipped surgical complex, >5000 square feet of laboratory space, a quarantaine facility, library, conference room, administrative offices, etc. More than 500 primates can be housed at IPR, mainly baboons. Reproductive research at IPR is applied to ...

SOME FUNCTIONAL-ANATOMICAL CHARACTERISTICS OF FINGER MOVEMENTS IN THE HANDS OF HUMAN AND OTHER PRIMATES Hasselt University
In human and non-human primates, at the level of the proximal interphalangeal joint of the finger, the arrangement of tendinous bands in the extensor assembly as well as the shape of the trochlea of the proximal phalanx determine the rate of release of the third phalanx as seen in e.g., ordinary opening and closing of the hand. In view of the importance of skilled forelimb movements and hand- and finger joint coordination, in prehensile ...
Evidence for adolescent length growth spurts in bonobos and other primates highlights the importance of scaling laws Royal Zoological Society of Antwerp
Adolescent growth spurts (GSs) in body length seem to be absent in non-human primates and are considered a distinct human trait. However, this distinction between present and absent length-GSs may reflect a mathematical artefact that makes it arbitrary. We first outline how scaling issues and inappropriate comparisons between length (linear) and weight (volume) growth rates result in misleading interpretations like the absence of length-GSs in ...
Flavivirus antibodies reactive to Zika virus detected in multiple species of nonhuman primates in Kenya, 2008-2017 Institute of Tropical Medicine
Background: Zika virus (ZIKV), first described in 1947, is an arthropod-borne virus associated with sporadic outbreaks and interepidemic transmission. Recent studies have implicated nonhuman primates (NHPs) as the probable reservoir hosts. We tested archived serum samples of NHPs collected in Kenya for evidence of neutralizing ZIKV antibodies.
Methods: We randomly selected 212 archived serum samples from Institute of Primate Research ...
Occurrence of Prosthenorchis elegans in Free-living Primates from the Atlantic Forest of Southern Bahia, Brazil Royal Zoological Society of Antwerp
Parasite prevalence and abundance are important factors affecting species’ conservation. During necropsies on a free-living golden-headed lion tamarin (Leontopithecus chrysomelas) and two Wied’s marmosets (Callithrix kuhlii) in the Atlantic Forest of southern Bahia, Brazil, we collected a large number of adult intestinal parasites that we identified as Prosthenorchis elegans. This parasite is pathogenic for Neotropical primates. Prosthenorchis ...
Molecular characterisation of Giardia duodenalis in captive non-human primates reveals mixed assemblage A and B infections and novel polymorphisms Royal Zoological Society of Antwerp Ghent University
Giardia is frequently detected in stools of non-human primates (NHP). However, a molecular identification has been rarely applied to Giardia isolates from NHP, and the distribution of the zoonotic assemblages A and B remains unclear. Moreover, little is known about the genetic variability among the isolates, although this may contribute to the elucidation of the different transmission pathways, including the role of NHP as a reservoir for human ...
Gastrointestinal protozoa in non-human primates of four zoological gardens in Belgium Royal Zoological Society of Antwerp Institute of Tropical Medicine
Gastrointestinal parasites are important infectious causes of diarrhoea in captive non-human primates (NHP). However, prevalence data of gastrointestinal parasites in zoological gardens are scarce. Therefore, a cross-sectional survey was conducted to estimate the occurrence of gastrointestinal parasites in NHP of four zoological gardens in Belgium. Between August 2004 and April 2006, 910 faecal samples were collected from 222 animals housed in ...
