Colobomas in Non-human Primates
Folia Primatologica, 1971Four cases of coloboma affecting various ocular structures in non-human primates are described. The gross and histologic features of each case are illustrated, and a possible reason for the lack of reports of this condition is discussed.

Ophthalmic Lesions in Non-Human Primates
Veterinary Pathology, 1971Over a 2-year period a number of spontaneous ophthalmic lesions were noted in non-human primates. These included lesions in baboons, old world monkeys, and chimpanzees. The lesions were divided into general etiologic categories of congenital, inflammatory, traumatic, degenerative, and undetermined.

Sequential learning in non-human primates
Trends in Cognitive Sciences, 2001Sequential learning plays a role in a variety of common tasks, such as human language processing, animal communication, and the learning of action sequences. In this article, we investigate sequential learning in non-human primates from a comparative perspective, focusing on three areas: the learning of arbitrary, fixed sequences; statistical learning;

Hydrogel keratophakia in non-human primates
Current Eye Research, 1981We performed sixteen keratophakia procedures in nine non-human primates using various hydrogel lenses (38% to 79% water) as donor corneas (lenticules). The lenses were treated as if they were donor human corneas using currently practiced keratophakia procedures including microkeratome resection of the recipient cornea, staining of the lenses before ...

Non-human primate dental arch form
Cells Tissues Organs, 1977Multivariate statistical analysis, based upon a number of dimensions, showed significant contrasts in dental arch form between four primate groups, which was difficult to identify from subjective visual inspection. Furthermore, analysis of dental arch size was shown to differ from dental arch shape, although whether this reflected predominantly genetic

Melioidosis in Imported Non-Human Primates
Journal of Wildlife Diseases, 1970In 1969, five cases of melioidosis in three separate outbreaks were diagnosed in nonhuman primates in the United States. In the first outbreak, two stump-tailed macaque monkeys (Macaca arctoides) developed signs of the disease approximately 6 months after purchase. A third animal, a chimpanzee (Pan troglodytes), probably acquired its infection from one

Hepatitis viruses in non‐human primates
Journal of Medical Primatology, 2006AbstractBackground Previous epidemiological studies of rural human populations in Gabon reveal a high prevalence of human hepatitis A, B, C and D viruses. In order to investigate the prevalence of the blood‐born hepatitis viruses in apes and monkeys living in the same area, we performed an epidemiological survey of HBV, HCV and HDV in wild‐born non ...

Experimental norovirus infections in non‐human primates
Journal of Medical Virology, 2004AbstractNoroviruses, with Norwalk virus as the prototype strain, are the most common cause of viral gastroenteritis in people of all ages. Limited information on the immunology of Norovirus infections has been obtained by studies both in the natural setting and in experimentally infected volunteers.

Non‐human primate models of multiple sclerosis
Immunological Reviews, 2001Summary: The phylogenetic proximity between non‐human primate species and humans is reflected by a high degree of immunological similarity. Non‐human primates therefore provide important experimental models for disorders in the human population that are caused by the immune system, such as autoimmune diseases.

1991
Abstract It is probably too much to hope that, except in the later stages where stratigraphic resolution is greatest, modes of evolution can be worked out in fossil primates. Gingerich and others tried it for Pelycodus and Plesiadapis, and it is still controversial.
