Background
Evaluation of blood parameters in captive non-human primates (NHPs) is crucial for monitoring their health and ensuring that their environment meets their physiological requirements.
Methods
We performed hemogram, serum biochemistry, and parasitological exams in 20 howler monkeys and 21 capuchin monkeys.
Results
In both species, over 50% of the individuals presented at least one parasite. There was a negative effect of age on red blood cell (RBC), white blood cell, platelets, total protein, globulin, and alkaline phosphatase, and a positive effect on the A:G ratio, gamma-glutamyl transferase, and mean platelet volume (MPV). Capuchin monkeys presented the highest platelets and alanine aminotransferase (ALT) values and howler monkeys presented the highest MPV, aspartate aminotransferase, ALT, amylase, glucose, bilirubin, and triglycerides values. We observed an interaction between species and sex on RBC, Htc, mean corpuscular hemoglobin concentration, and cholesterol.
Conclusions
Species differences found in blood parameters may reflect differences in physiological adaptations associated with ecological and morphological traits and are clinically relevant for evaluating animal health and the suitability of breeding programs.

Congenital digital defects, particularly adactyly and oligodactyly, have been reported frequently in humans, however, their occurrence in rhesus monkeys is rare, mainly in the hind limbs. We present here for the first time, two female rhesus monkeys with unilateral congenital toe defects with metatarsal involvement. One showing adactyly and the other oligodactyly. In this report, we present the clinical/radiological details of these cases as well as discuss the risk factors possibly involved, such as contact with pesticides and genetic factors.

Background
Melatonin is a multifunctional hormone synthesized in the pineal gland and peripheral reproductive tissues that regulates many biological processes. There is increasing evidence for a role of melatonin in oocyte maturation and embryonic development in various mammals. However, no study has reported evidence for the existence of melatonergic system, such as melatonin synthesis enzymes, melatonin membrane receptors, or melatonin binding sites in non-human primate cumulus–oocyte complexes (COCs).
Methods
Reverse transcription polymerase chain reaction (RT-PCR) and immunocytochemistry were performed to detect transcripts and proteins of the rate-limiting enzyme in melatonin synthesis (arylalkylamine N-acetyltransferase, AANAT), melatonin membrane receptors (MT1 and MT2), and a melatonin binding site (NRH: quinone oxidoreductase 2, NQO2) in cynomolgus monkey COCs.
Results
RT-PCR analyses revealed the presence of AANAT, MT1, MT2, and NQO2 transcripts in granulosa cells, germinal vesicle (GV)- and metaphase II (MII)-stage cumulus cells, and oocytes. Immunocytochemistry revealed the presence of AANAT, MT1, MT2, and NQO2 proteins in GV- and MII-stage COCs.
Conclusions
Our results provide the first evidence for the existence of the rate-limiting enzyme required for melatonin synthesis, melatonin membrane receptors, and a melatonin binding site in non-human primate COCs.

Diagnosis and treatment of atopic dermatitis (AD) in chimpanzees are challenging. Validated allergy tests specific for chimpanzees are not available. A multifactorial management of atopic dermatitis is important. Successful management of AD has, to the best knowledge of the authors, not been described in chimpanzees.

Background
This study evaluated the anesthetic and cardiorespiratory effects of two anesthetic protocols for salpingectomy or deferentectomy in capuchin monkeys (Sapajus sp).
Materials and Methods
Five capuchin monkeys (5 per group) received ketamine (20 mg/kg) combined with midazolam (0.5 mg/kg; group KM) or dexmedetomidine (5 μg/kg; group KD) intramuscularly. Anesthesia is induced with propofol intravenously and maintained with isoflurane. Before the start of surgery, fentanyl 3 μg/kg was administered IV, and continuous infusion (10 μg/kg/min) IV was started. Times and quality of anesthetic recovery were evaluated postoperatively.
Results
KM and KD resulted in adequate chemical restraint. KD resulted in bradycardia. Intraoperative heart rate and systolic blood pressure were higher in KM than in KD. Both groups had smooth recovery. Time to standing was longer in KM than in KD.
Conclusion
Both protocols allowed the performance of surgeries, with few cardiorespiratory effects. Anesthetic recovery was smooth and shorter in KD group.

Urinalysis is a rapid, non‐invasive method used to obtain diagnostic information on primates. While several studies have investigated dipstick and specific gravity values in chimpanzees, urine sediment analysis is often excluded.

Background
Compatible pair housing of macaques in research settings increases species-typical behaviors and facilitates beneficial social buffering. It is not yet established whether these benefits are maintained after intrafacility transfer and domestic quarantine, which are two stressors that can lead to behavioral and clinical abnormalities.
Methods
We evaluated 40 adolescent male rhesus macaques who were single- or pair-housed immediately following an intrafacility transfer. We measured behavior, fecal cortisol, body weight, and diarrhea occurrence. Body weight and diarrhea occurrence were also retrospectively analyzed in an additional 120 adolescent rhesus who underwent a similar transfer.
Results and Conclusions
Pair-housed macaques exhibited less of some undesirable behaviors (e.g., self-clasping) and experienced less diarrhea than single-housed subjects; however, no significant differences in cortisol levels or alopecia measures were found. The demonstrated beneficial effects of pair housing for rhesus macaques following intrafacility transfer and adjustment suggest pairing upon arrival at a new facility will bolster animal welfare.
