Faecal Samples

Faecal samples and blood films from 3 species of Old-World monkeys, Macaca mulatta, Macaca irus and Papio dogeura, were examined for the presence of nematode parasites. 8 separate groups, a total of 200 animals, were examined within 24 hours of their arrival at the premises of a primate importer. 8 species of nematode were found to be common inhabitants of the alimentary tract, and small numbers of microfilaria were detected in all groups.

Histopathologic Findings

Histological lesions in the lungs of rhesus monkeys (Macaca mulatta) related with Pneumonyssus simicola were evidenced. The most prominent pathologic alterations included numerous thin-walled cysts 1-5 mm diameter scattered throughout the lungs, bronchiolitis, peribronchiolitis where the mites were found associated with pigmented and non-pigmented materials. Our study included data from 347 rhesus monkeys submitted to necropsies during 20 years. Four adult debilitated animals were found with pulmonary acariasis which showed a very low incidence of parasite (1.2%) in the colony. Most of the published literature described as common and widespread pulmonary acariasis in Old World monkeys. The present study confirms the ubiquity of P. simicola in captive born and raised rhesus monkeys that would compromise experimental studies involving the respiratory system.

In recent years, non-human primates have become indispensable as experimental animals in many fields of biomedical research. Pharmaceutical and related industries alone use about 2000,000 primates a year. Respiratory mite infestations in lungs of old world monkeys are of particular concern because the resulting tissue damage can directly effect experimental results, especially in those studies involving the cardiopulmonary system. There has been increasing documentation of primate parasitology in the past twenty years.

Recent Duplication

The disabilities experienced by colour-blind people show us the biological advantages of colour vision in detecting targets, in segregating the visual field and in identifying particular objects or states. Human dichromats have especial difficulty in detecting coloured fruit against dappled foliage that varies randomly in luminosity; it is suggested that yellow and orange tropical fruits have co-evolved with the trichromatic colour vision of Old World monkeys. It is argued that the colour vision of man and of the Old World monkeys depends on two subsystems that remain parallel and independent at early stages of the visual pathway. The primordial subsystem, which is shared with most mammals, depends on a comparison of the rates of quantum catch in the short- and middle-wave cones; this system exists almost exclusively for colour vision, although the chromatic signals carry with them a local sign that allows them to sustain several of the functions of spatiochromatic vision. The second subsystem arose from the phylogenetically recent duplication of a gene on the X-chromosome, and depends on a comparison of the rates of quantum catch in the long- and middle-wave receptors. At the early stages of the visual pathway, this chromatic information is carried by a channel that is also sensitive to spatial contrast. The New World monkeys have taken a different route to trichromacy: in species that are basically dichromatic, heterozygous females gain trichromacy as a result of X-chromosome inactivation, which ensures that different photopigments are expressed in two subsets of retinal photoreceptor.
