Reproduction of the owl monkey (Aotus spp.) in captivity.

The reproduction performance of captive owl monkeys, a breed used extensively in biomedical research, was observed at the Battelle Primate Facility (BPF). The colony grew through captive breeding, imports from the Peruvian Primatological Project, and others to a peak size of 730. It included seven karyotypes of Aotus sp.

Serum and urine biochemical diversity among adult wild-caught Aotus nancymae and Saimiri peruviensis.

Serum and urine analytes were compared between adult wild-caught owl monkeys (Aotus nancymae) and adult wild-caught squirrel monkeys (Saimiri peruviensis) to determine if normative clinical pathology data were similar. An objective of the study was to confirm that species of neotropical primates are distinct with regard to physiologic parameters, and should not be considered interchangeable in biomedical research. Significant differences (P < 0.

Ultrasound-guided cholecystocentesis in the owl monkey.

Bile samples were obtained from adult owl monkeys by ultrasound-guided percutaneous cholecystocentesis, using a transhepatic approach. Sampling frequency was once weekly over a 5-week period. Clinical recovery from each procedure was rapid.

Serum and urine biochemical diversity among wild-caught and colony-born Aotus nancymae.

Serum and urine analytes were compared between adult wild-caught and adult colony-born owl monkeys (Aotus nancymae), to determine if normative clinical pathology data were similar. Significant differences (P < or = 0.05) were noted in serum protein, glucose, sodium, urine calcium, calcium clearance, and fractional clearance of calcium between the two groups.
