SEROLOGICAL DETECTION OF HEPATITIS A VIRUS IN FREE-RANGING NEOTROPICAL PRIMATES (Sapajus spp., Alouatta caraya) FROM THE PARANÁ RIVER BASIN, BRAZIL

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 2016
Nonhuman primates are considered as the natural hosts of Hepatitis A virus (HAV), as well as other pathogens, and can serve as natural sentinels to investigate epizootics and endemic diseases that are of public health importance. During this study, blood

How task format affects cognitive performance:a memory test with two species of New World monkeys [PDF]

open access: yes, 2016
In cognitive tests, animals are often given a choice between two options and obtain a reward if they choose correctly. We investigated whether task format affects subjects' performance in a physical cognition test.

The prion protein and New World primate phylogeny

open access: yesGenetics and Molecular Biology, 2004
The PrP C prion protein contains 250 amino acids with some variation among species and is expressed in several cell types. PrP C is converted to PrP Sc by a post-translational process in which it acquires amino acid sequences of three-dimensional ...

Inter- and intra-specific gene-density-correlated radial chromosome territory arrangements are conserved in Old World monkeys [PDF]

open access: yes, 2005
Recently it has been shown that the gene-density correlated radial distribution of human 18 and 19 homologous chromosome territories (CTs) is conserved in higher primates in spite of chromosomal rearrangements that occurred during evolution.

A perspective on color vision in platyrrhine monkeys [PDF]

open access: yes, 1960
Studies carried out over the past two decades show that many platyrrhine (New World) monkeys have polymorphic color vision. This condition results from the sorting of allelic versions of X-chromosome cone opsin genes at a single gene site, yielding a ...

Nutritional and health status of woolly monkeys [PDF]

open access: yes, 2008
Woolly monkeys (Lagothrix lagotricha and L. flavicauda) are threatened species in the wild and in captivity. Numerous zoological institutions have historically kept Lagothrix lagotricha spp., but only a few of them have succeeded in breeding populations.

Fast and non-invasive PCR sexing of primates: apes, Old World monkeys, New World monkeys and Strepsirrhines

open access: yesBMC Ecology, 2006
Background One of the key tools for determining the social structure of wild and endangered primates is the ability to sex DNA from small amounts of non-invasive samples that are likely to include highly degraded DNA.

Easy rider: monkeys learn to drive a wheelchair to navigate through a complex maze. [PDF]

open access: yesPLoS ONE, 2014
The neurological bases of spatial navigation are mainly investigated in rodents and seldom in primates. The few studies led on spatial navigation in both human and non-human primates are performed in virtual, not in real environments.
