Clinical and Pathologic Features of Spontaneous Infection in 9 Rhesus Macaques ().

is a gram-negative bacterium found in the environment and as a commensal in humans and animals. In humans, is one of the most serious nosocomial infections encountered currently and is characterized by liver abscesses, pneumonia, and bacteremia resulting in meningoencephalitis and endophthalmitis. in veterinary medicine is rarely reported in NHP, and recent literature describing this disease is sparse.

The contraceptive efficacy of intravas injection of Vasalgel™ for adult male rhesus monkeys.

Background: Options for male contraception are limited. The purpose of this study was to use a nonhuman primate model to evaluate Vasalgel™, a high molecular weight polymer being developed as a contraceptive device for men.

Methods: Sixteen adult male rhesus monkeys received intravas injections of Vasalgel, consisting of 25% styrene maleic acid in dimethyl sulfoxide.

Granuloma Due to Oxidized Regenerated Cellulose in an Aged Rhesus Macaque (Macaca mulatta).

Bioabsorbable hemostatic agents such as oxidized regenerated cellulose are widely used to control intraoperative diffuse capillary bleeding. Compared with electrocautery or ligation, oxidized regenerated cellulose has the advantage of controlling bleeding without occluding the vessel lumen or causing thermal injuries to adjacent tissue. Although the manufacturer recommends removal of the material once hemostasis is achieved, oxidized regenerated cellulose is a bioabsorbable hemostatic agent and is often left in the surgical bed to prevent subsequent bleeding after surgical closure.

Vaginal Stone in a Cynomolgus Macaque (Macaca fascicularis).

A 20-y-old female cynomolgus macaque (Macaca fascicularis) housed in an indoor primate facility presented for poor appetite and acute weakness after several years of no adverse health events. Physical examination revealed a firm, ovoid mass in the caudal abdomen. Further evaluation revealed the mass to be a vaginal calculus composed of calcium carbonate, apatite, and struvite.

Clinical allograft of a calcaneal tendon in a rhesus macaque (Macaca mulatta).

A 5.5-y-old male rhesus monkey (Macaca mulatta) housed in an outdoor field cage presented for severe trauma involving the left calcaneal tendon. Part of the management of this wound included an allograft of the calcaneal tendon from an animal that was euthanized for medical reasons.

Haemoproteus spp. and Leukocytozoon spp. in a captive raptor population.

Raptors are commonly infected with two blood parasites of the family Haemoproteidae, Haemoproteus spp. and Leukocytozoon spp. To determine if age or length of time in captivity influence prevalence of Haemoproteus spp.

Diagnosis and seroprevalence of leptospirosis in California sea lions from coastal California.

The sensitivity and specificity of the microscopic agglutination test (MAT) as a method for detection of exposure to Leptospira spp. in California sea lions (Zalophus californianus) were determined. Sera came from individuals that demonstrated clinical signs of renal disease, had lesions suggestive of leptospirosis at necropsy, and had visible leptospires in silver stained kidney sections as positive controls.
