BACKGROUND: Macaques are outstanding animal models for the development of new contraceptives. In women, progestin-only contraceptives often fail to block ovulation and are believed to act by altering cervix physiology. Herein, we assessed oviductal glycoprotein 1 (OVGP1) in the macaque cervix as a marker for progestogen action. MATERIALS: Rhesus macaques were treated with estradiol (E2 ), E2 plus progesterone (P), and E2 plus levonorgestrel (LNG), a contraceptive progestin...

We investigated menstrual cycles in intrauterine growth restricted (IUGR, 7-10 years, n = 8) and age-matched control (n = 10) baboons. Cycle duration and plasma anti-Mullerian hormone were similar. IUGR spent more days per cycle swollen and had elevated early morning fasted serum cortisol, suggesting normal fertility in the presence of increased psychosocial stress.

The gross anatomy of the palmaris longus muscle in 12 specimens of Saguinus leucopus was studied by dissection. This muscle was constant and unipennate, originated in the medial epicondyle of the humerus; inserted onto flexor retinaculum and palmar aponeurosis; and innerved by the median nerve, and in one case, together with the ulnar nerve. This is the first report of double innervation for this muscle in primates.

BACKGROUND: We present 3 likely cases of testicular dysgenesis syndrome (TDS) within a community of chimpanzees (Pan troglodytes schweinfurthii). We tested whether genetic drift may be the culprit, as a genetic cause has been suspected to account for TDS among other wildlife. METHODS: We successfully sequenced a 367-bp segment spanning the first hypervariable region within the D-loop of the mitochondrial genome for 78 DNA samples. RESULTS: We found 24 polymorphic sequence sites consisting of 7 singletons and 17 parsimony informative sites...

BACKGROUND: We hypothesized that maternal nutrient restriction (NR) would increase activity and behavioral indicators of anxiety (self-directed behaviors, SDBs) in captive baboons (Papio sp.) and result in more protective maternal styles. METHODS: Our study included 19 adult female baboons. Seven females ate ad libitum (control group), and eight females ate 30% less (NR group) and were observed through pregnancy and lactation. RESULTS: Control females engage in higher rates of SDB than NR females overall (P ≤ ...

We describe the first case of biliary cirrhosis in Japanese macaque. Clinical signs had not been detected. The liver was nodular. Histopathologically, portal-to-portal pattern of fibrosis might have indicated chronic cholestasis. Fibrotic septa were infiltrated with inflammatory cells. Therefore, this case could be diagnosed as active incomplete biliary cirrhosis.

BACKGROUND: Toxoplasma gondii (T. gondii) is an intracellular protozoan parasite that can infect warm-blooded animals including humans. New World monkeys, such as squirrel monkeys, are more susceptible to T. gondii than Old World monkeys, often developing fatal disease. METHODS: In this study, seven of thirteen dead squirrel monkeys at Seoul Grand Park were tested to find the cause of sudden death. RESULTS: The main histopathological findings included interstitial pneumonia, necrotizing hepatitis, and splenitis...

BACKGROUND: The advent of non-invasive methods provides a powerful alternative to stress studies as the use of stressful handling techniques is no longer needed. However, many factors influence hormone metabolism such as sex, diet, and metabolic rate. Thus, validation should be species- and matrix-specific. METHODS: To assess stress response in brown howler monkeys Alouatta clamitans, we adopted an ACTH challenge test and parallelism to provide physiological and laboratorial validation...

BACKGROUND: It is generally accepted that non-human primates (NHP) represent the model of choice for integrative studies of testicular function and endocrine control. However, there are many species-specific differences that necessitate identification prior to the selection of an appropriate model for these studies. In an NHP breeding facility, this opportunity of selection is usually presented during breeding periods when it is crucial to determine which individuals should be maintained as breeders...

BACKGROUND: Retrospective analysis of post-operative vomiting (POV) in non-human primates at our institution was 11%. Based on this additional risk factor for post-operative complications, we aimed to eliminate or decrease POV by adding an antiemetic, maropitant citrate, to the pre-medication protocol. METHODS: Retrospective and prospective data were collected over a 5-year period from 46 macaques of two species during 155 procedures. Additionally, blood was collected from five Macaca mulatta to perform a pharmacokinetic analysis...

Cutaneous neoplasia is common in non-human primates. We describe the gross and microscopic features of multicentric cutaneous keratoacanthomas in a free-living marmoset (Callithrix sp.). Immunohistochemistry for human papillomavirus and herpes simplex virus type I and simplex virus type II was negative. Keratoacanthomas should be included in the differential diagnosis for cutaneous masses in non-human primates.
