Perception of chasing in squirrel monkeys (Saimiri sciureus)

Animal Cognition, 2015
Understanding the intentions of others is crucial in developing positive social relationships. Comparative human and non-human animal studies have addressed the phylogenetic origin of this ability. However, few studies have explored the importance of motion information in distinguishing others' intentions and goals in non-human primates.

Ureteral Reflux in the Squirrel Monkey (Saimiri sciureus)

American Journal of Veterinary Research, 1971
SUMMARY 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.

Fertilization in vitro of Saimiri sciureus Follicular Oocytes

Journal of Medical Primatology, 1975
An in vitro fertilization system was developed for the squirrel monkey. Oocytes recovered from follicles of gonadotropin-treated females and cultured in vitro with spermatozoa resulted in fertilized ova capable of developing to the four-cell stage in culture.

Mycobacterium kansasii infection in squirrel monkeys (Saimiri sciureus sciureus)

Journal of Medical Primatology, 1995
Abstract: 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 contrast sensitivity of the squirrel monkey (Saimiri sciureus)

Vision Research, 1976
Abstract 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.

The Squirrel Monkey (Saimiri sciureus)

1983
The 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, 1985
The 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, 2000
Splenectomised 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, 2011
Toxoplasma 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

Elevation in Plasma Glucagon Levels in Response to Stress in Squirrel Monkeys: Comparisons of Two Subspecies (Saimiri sciureus boliviensis and Saimiri sciureus sciureus)

Journal of Medical Primatology, 1988
Bolivian (Bo) and Brazilian (Br) squirrel monkeys (SMs) were captured and restrained to determine patterns of glucagon and glucose response. In both subspecies, plasma glucagon and glucose levels rose rapidly in response to restraint procedures; glucagon levels in BrSMs and glucose levels in both subspecies returned to basal values in 15 minutes.
