Chromosomal Polymorphism and Somatic Segregation in Saimiri sciureus
Folia Primatologica, 1979Quinacrine (Q) and Giemsa (G) banding, and sister chromatid exchange (SCE) studies have been carried out in Saimiri sciureus. In one male and one female studied, the diploid number was 2n = 44 and the karyotype corresponded to that described for the geographical region of Georgetown, Guyana.

The Thatcher illusion in squirrel monkeys (Saimiri sciureus)
Animal Cognition, 2012Like humans, Old World monkeys are known to use configural face processing to distinguish among individuals. The ability to recognize an individual through the perception of subtle differences in the configuration of facial features plays an important role in social cognition.

Ureteral Reflux in the Squirrel Monkey (Saimiri sciureus)
American Journal of Veterinary Research, 1971SUMMARY Twenty urinary samples obtained from 4 female squirrel monkeys (Saimiri sciureus) were measured. The volume of individual urinary samples ranged between 3 and 7.9 ml. (mean 4.415 ml. ± 1.45). Cystograms were prepared in 6 female squirrel monkeys to study ureteral reflux. Bilateral ureteral reflux was observed in 4 of 6 monkeys.

Saimiri sciureus (Squirrel monkey)
1973The karyotypes shown are a gift of Dr. T. C. Jones (New England Regional Primate Research Center, Southborough, Massachusetts) and were prepared from lymphocyte cultures. The two recognized phenotypes also differ in karyotype: the male came from Leticia (Colombia), and the female, from Iquitos (Peru).

The contrast sensitivity of the squirrel monkey (Saimiri sciureus)
Vision Research, 1976Abstract The contrast sensitivity of three squirrel monkeys and two human subjects was measured under similar conditions with a modified method of constant stimuli. Sensitivity was greatest for all subjects at 2–5c/deg and declined at higher and lower spatial frequencies.

Mycobacterium kansasii infection in squirrel monkeys (Saimiri sciureus sciureus)
Journal of Medical Primatology, 1995Abstract: This report documents asymptomatic infections of Mycobacterium kansasii in four of five tuberculin positive squirrel monkeys (Saimiri sciureus sciureus). The mycobacterial DNA amplified by polymerase chain reaction (PCR) from a bronchial lymph node had no affinity for the species specific probes of M. tuberculosis, M.

The Squirrel Monkey (Saimiri sciureus)
1983The squirrel monkey (Saimiri sciureus) is widely distributed in Central and South America between the 17°S and 10°N latitudes. They are particularly prevalent on the Pacific side of Central America and throughout the Amazon basin. For as long as 400 years they have been captured and traded as pets for the homes of the aristocracy of Europe and America.

Lipid composition of squirrel monkey (Saimiri sciureus) saliva
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985The content and composition of lipids in saliva of healthy caries-free squirrel monkeys were investigated. The dialyzed and lyophilized saliva on extraction with chloroform/methanol yielded 8.0 +/- 0.9 mg of lipids/100 ml of saliva. Following fractionation on silicic acid column, 30.9% of lipids were found in the neutral lipid fraction, 58.8% in the ...

Chemotherapy of haemobartonellosis in squirrel monkeys (Saimiri sciureus)
Journal of Medical Primatology, 2000Splenectomised Saimiri sciureus squirrel monkeys are being used increasingly as an experimental host for human malarial studies, notably for the assessment of candidate vaccines against Plasmodium falciparum blood‐stage infection. Recently, we have reported that colony‐reared S. sciureus monkeys are asymptomatic carriers of Haemobartonella sp. and

Acute toxoplasmosis in squirrel monkeys (Saimiri sciureus) in Mexico
Veterinary Parasitology, 2011Toxoplasma gondii causes fatal multisystemic disease in New World primates, with respiratory failure and multifocal necrotic lesions. Although cases and outbreaks of toxoplasmosis have been described, there are few genotyping studies and none has included parasite load quantification. In this article, we describe two cases of lethal acute toxoplasmosis
