BACKGROUND: Under the environment of pregnancy, the placenta assumes an important steroidogenic role in the maintenance of pregnancy. METHODS: Urinary placental leucine aminopeptidase (PLAP), estrone-3-glucuronide (E1 G), and pregnanediol-3-glucuronide (PdG) concentrations were compared among five pregnancies (four live births and one stillbirth) in four orangutans. RESULTS: The gestation period of the stillbirth (223 days) was shorter than that of the live births (239-254 days)...

BACKGROUND: A uterine neoplasm was observed, as an incidental finding, during post-mortem examination of a 26-year-old female multiparous African green monkey (Chlorocebus aethiops sabaeus). The intramural, expansile, 2 to 3 cm well-demarcated, dark-red, nodular neoplasm was located on the anterior uterine body (corpus) wall. METHODS: The mass was examined by light microscopy and by immunohistochemistry. RESULTS: The mass was confirmed as a cavernous uterine angioleiomyoma (syn...

Papio hamadryas papillomavirus (PhPV) 1, 2, and 3, are Alphapapillomaviruses that have been detected in Kenyan Olive baboons but the distribution is unknown. Therefore, cervical screening for PhPV1 was performed in baboons from various areas in Kenya using a nested polymerase chain reaction. The prevalence rate was 33%.

BACKGROUND: Non-human primates infected with simian immunodeficiency virus (SIV) represent a robust model to evaluate pre-clinical efficacy of HIV-1 preventive strategies and to determine the size of reservoir. METHODS: We developed a real-time qPCR assay to specifically quantify episomal 2-LTR circular DNA in peripheral blood mononuclear cells and brain tissues from SIV-infected macaques. RESULTS: This assay has sensitivity, accuracy and reproducibility over seven orders of magnitude...

BACKGROUND: For the past 30 years, Simian AIDS has provided an indispensible animal model for the human disease. This historical perspective highlights the circumstances leading to the creation of this experimental model. METHODS: Historical information and stored non-human primate (NHP) specimens, including isolates of Simian immunodeficiency virus (SIV), were analyzed by molecular epidemiologic methods to trace the lineage and transmission of SIV among NHPs at US primate centers...

BACKGROUND: The primate model of bipedal locomotion has been extensively used to study human evolution and played a critical role in exploring the pathological mechanisms of human neurologic disease and spinal cord injury. Speed has great influence on both walking posture and gait parameters in human walking; however, how speed changes the gait pattern of bipedal locomotion in primates remains unclear. METHODS: We chose six adult female rhesus monkeys (Macaca mulatta) and collected the gait parameters of these animals during their treadmill locomotion over a wide range of speed...

BACKGROUND: Sapajus flavius is a species of capuchin monkey classified as critically endangered. Studies related to their biometric values are scarce with incomplete external measurement reports available from only four specimens. Moreover, information regarding proteinogram is limited with no reference to C-reactive protein (CRP) and globulin fractions for this species. METHODS: Biometric values, CRP, and proteinogram were determined for 12 clinically healthy S...

BACKGROUND: Obesity in pregnancy (MO) is a risk factor for maternal and/or fetal cardiovascular system disorders. This study evaluated maternal CVS expression of microRNA-29 family and its target molecules in MO to test the hypotheses: CVS miR-29 concentrations are increased in pregnancy and decreased in MO. METHODS: Non-pregnant (n=4), pregnant obese (POb, n=4), and pregnant non-obese (PnOb, n=4) baboons (Papio spp.) were studied. Maternal left ventricle (LV), left atrium (LA), and aortic arch (AA) were collected at the end of gestation...

A laparoscopic appendectomy was performed in a wild orangutan (Pongo pygmaeus) undergoing rehabilitation, for a metal nail found on radiographs, using 3-mm instrumentation. Post-operative healing was rapid and uneventful, with return to the forest within 10 days. This is the first report of minimally invasive surgery in a wild orangutan.

BACKGROUND: Crescentic glomeruli are the hallmark finding in rapidly progressive glomerulonephritis (RPGN) and are characterized by disruption and proliferation of the glomerular capsule and an influx of cells into Bowman's space. Pauci-immune-type RPGN is identified by a lack of immunoglobulins and immune complexes in the glomerular basement membrane. METHODS: Complete necropsy and histology were performed on the affected chimpanzee. Electron microscopy was performed on kidney sections...

BACKGROUND: The Mauritian cynomolgus macaque (Macaca fascicularis) is widely used in biomedical research. Determining reference intervals for biochemical and haematological analytes provides an important tool for clinical diagnosis and pre-clinical research. METHODS: Blood samples from 736 Mauritian long-tailed macaques were analysed to determine reference intervals of 13 biochemical and 10 haematological analytes. The need for partitioning the reference interval between males and females was determined...

BACKGROUND: Klebsiella pneumoniae can be a serious pathogen in non-human primates, particularly Neotropical monkeys. METHODS: During a K. pneumoniae outbreak in an owl monkey research colony, 13 K. pneumoniae isolates were DNA fingerprinted by automated repetitive extragenic palindromic-polymerase chain reaction and the profiles compared to isolates obtained from other non-human primate species during the same time period and isolates from previous outbreaks. RESULTS: Eleven different types of K...

Two cases of hepatic myelolipoma in Goeldi's monkeys from South America are described. One was a female evaluated due progressive abdominal distension. Ultrasound and computed tomography detected hepatic mass. Partial hepatectomy was performed, but the monkey died after surgery. Case 2 was a male that died suddenly, showing non-specific clinical signs.

Autoimmune bullous disease is very uncommon in non-human primates. We observed a bullous skin disease in a male rhesus monkey while conducting porcine islet xenotransplantation. Fifty days after the transplantation, multiple bullous skin lesions were observed. There was no mucosal involvement. Skin biopsy results demonstrated a subepidermal blister with no necrotic keratinocytes. Immunofluorescent staining showed linear IgG deposition at the roof of the blister. These skin lesions spontaneously disappeared...

BACKGROUND: An adult male galago (Otolemur garnettii) presented for fight wounds following pairing for breeding. Treatment was symptomatic with recovery. Following resolution, the animal re-presented and died, despite additional treatment. METHODS: Necropsy, histopathology, bacterial cultures, and 16S RNA sequencing. RESULTS: A large intrathoracic/intra-abdominal abscess due to Trueperella pyogenes was found at necropsy. CONCLUSIONS: T...

BACKGROUND: Non-ketotic hyperglycinaemia (NKH) is an autosomal recessive inborn error of glycine metabolism characterized by accumulation of glycine in body fluids and various neurological symptoms. METHODS: This study describes the first screening of NKH in cataract captive-bred vervet monkeys (Chlorocebus aethiops). Glycine dehydrogenase (GLDC), aminomethyltransferase (AMT) and glycine cleavage system H protein (GCSH) were prioritized. RESULTS: Mutation analysis of the complete coding sequence of GLDC and AMT revealed six novel single-base substitutions, of which three were non-synonymous missense and three were silent nucleotide changes...

BACKGROUND: The anatomical literature on the genus Macaca has focused mainly on the rhesus monkey. However, some aspects in the positional behaviors of the Japanese monkey may be different from those in rhesus monkey, suggesting that the anatomical details of these species are divergent. METHODS: Four thoracic limbs of Macaca fuscata adults were dissected. RESULTS: The arm muscles in Japanese macaques are more similar to rhesus monkeys and Papio; these characteristics are closer to those of bearded capuchins than apes, indicating more proximity of this genus to New World primates...

A rhesus macaque (Macaca mulatta) was presented for anuria. Examination revealed calcium oxalate concrements in the bladder. A cystotomy was performed, and a therapy with alfuzosin was conducted. Over 1 year after the treatment, the rhesus macaque had not shown any more signs of stranguria. This is the first case reporting the successful treatment of urolithiasis in a rhesus macaque.
