BACKGROUND: Epidural anesthesia is indicated to decrease other anesthetic requirements, prolong analgesia, and reduce side effects. In primates, its use has been scarcely described. The aim was to evaluate the cardiorespiratory effects of epidural anesthesia with lidocaine and dexmedetomidine (DEX) or morphine (MOR). METHODS: Ten female capuchin monkeys (Sapajus sp.) received epidural anesthesia with lidocaine and DEX or MOR under general anesthesia. RESULTS: There was a significant decrease in heart rate with DEX and in blood pressure in all groups, with no changes in SpO2 ...

BACKGROUND: The scarcity of data on the anatomy of Sapajus libidinosus has impeded the execution for appropriate veterinary treatment. The objective of this study was to describe the main peripheral veins of the capuchin monkey, used in venipuncture and indicate the best access route for venipuncture procedures. METHODS: Ten S. libidinosus corpses were used. The face, neck, chest, and pelvic limb were dissected using surgical instruments to identify and locate surface vessels...

BACKGROUND: Hypervirulent strain of Klebsiella pneumoniae genotype K1 isolates have recently emerged, causing severe pyogenic liver abscess complicated by devastating metastatic infections in humans. METHODS: We describe a short outbreak of the non-human primate (NHP) research center, associated with a hypervirulent K. pneumoniae. The genetic similarity of the strains was evaluated by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) techniques, and virulence encoding genes were detected by polymerase chain reaction (PCR)...

Pneumatosis intestinalis (PI) has been described as an incidental finding in domestic animals and humans where it is associated with human immunodeficiency virus infection among other comorbidities. This report describes emphysematous changes consistent with PI in a simian immunodeficiency virus (SIV)-infected rhesus macaque (Macaca mulatta).

BACKGROUND: Most developmental programming studies on maternal nutrient reduction (MNR) are in altricial rodents whose maternal nutritional burden and offspring developmental trajectory differ from precocial non-human primates and humans. METHODS: Control (CTR) baboon mothers ate ad libitum; MNR mothers ate 70% global control diet in pregnancy and lactation. RESULTS: We present offspring morphometry, blood cortisol, and adrenocorticotropin (ACTH) during second half of gestation (G) and first three postnatal years...

We report cryoglobulinaemia (CG) in a rhesus macaque whose serum sample was gel-like at <37°C and resolubilised upon warming. Mixed CG was diagnosed using serum protein electrophoresis and serum immunofixation electrophoresis. Renal damage and arthrophyma were observed during necropsy. This is the first report of CG in a non-human primate.

A female rhesus macaque developed two episodes of generalized convulsions during transcutaneous spinal cord stimulation (TSCS) and urodynamic studies under ketamine anesthesia. The seizures took place in the absence of active TSCS and bladder pressure elevation. Ketamine anesthesia remains the primary risk factor for the convulsions during these experimental procedures.

BACKGROUND: Loss and fragmentation of Neotropical primates' habitat can alter the health and individual adaptation. Physiological parameters reflect health status and individuals responses to the habitat conditions. METHODS: We captured six wild adult females and six adult males of Alouatta pigra to evaluate their physical condition (body mass, respiratory and heart rate, and rectal temperature), hematology and blood chemistry on fragmentation habitat condition at southeastern Mexico...

Rhesus macaques experimentally infected with Simian Immunodeficiency Virus (SIV) experience immunosuppression and often opportunistic infection. Among the most common opportunistic infections are rhesus cytomegalovirus (RhCMV), a ubiquitous betaherpesvirus that undergoes continuous low-level replication in immunocompetent monkeys. Upon SIV-mediated immunodeficiency, RhCMV reactivates and results in lesions in numerous organ systems including the nervous and reproductive systems. We report the first case of cytomegaloviral hypophysitis in a SIV-immunocompromised rhesus macaque...

Recrudescence of latent and dormant viruses may lead to overwhelming viremia in immunosuppressed hosts. In immunocompromised hosts, Simian virus 40 (SV40) reactivation is known to cause nephritis and demyelinating central nervous system disease. Here, we report SV40 viremia leading to fatal interstitial pneumonia in an immunosuppressed host following renal allotransplantation.

Cytochromes P450 (P450) largely remain to be characterized in great apes. Comparative immunochemical detection of drug metabolizing forms of P450s 1A, 2A, 2B, 2C, 2D, 2E, 2J, 3A, 4A, and 4F in liver microsomes from chimpanzees, gorillas, orangutans, gibbons, cynomolgus and rhesus macaques, and common marmosets were carried out.

We present the spontaneous pathological lesions identified as a result of necropsy or biopsy for 245 chimpanzees (Pan troglodytes) over a 35-year period. A review of the pathology database was performed for all diagnoses on chimpanzees from 1980 to 2014. All morphologic diagnoses, associated system, organ, etiology, and demographic information were reviewed and analyzed. Cardiomyopathy was the most frequent lesion observed followed by hemosiderosis, hyperplasia, nematodiasis, edema, and hemorrhage. The most frequently affected systems were the gastrointestinal, cardiovascular, urogenital, respiratory, and lymphatic/hematopoietic systems...

BACKGROUND: Rhesus and cynomologus macaques are valuable animal models for the study of human immunodeficiency virus (HIV) prevention strategies. However, for such studies focused on the vaginal route of infection, differences in vaginal environment may have deterministic impact on the outcome of such prevention, providing the rationale for this study. METHODS: We tested the vaginal environment of rhesus and cynomolgus macaques longitudinally to characterize the normal microflora based on Nugent scores and pH...

As captive rhesus macaques often exhibit hair loss, alopecia was quantified and behavior was recorded before, during, and after fatty acid supplementation in six macaques. Fatty acid treatment was associated with a decrease in alopecia and in self-grooming behavior. Therefore, fatty acids may be a viable treatment for alopecia in some captive primates.

Simian betaretroviruses include the well-known exogenous simian retroviruses (SRV-1 through SRV-8), and some closely related simian endogenous retroviruses (SERV). Here, we characterized two new viral genomes, which appear to represent novel SERVs but have characteristics of both SRV and SERV highlighting the need to develop new assays providing molecular and serologic differentiation of SERV and SRV to avoid false positives.

BACKGROUND: Although HSV-2 is the major cause of genital lesions, HSV-1 accounts for half of new cases in developed countries. METHODS: Three healthy SHIV-SF162P3-infected Indian rhesus macaques were inoculated with 4×10(8) pfu of HSV-1 twice, with the second inoculation performed after the vaginal mucosa was gently abraded with a cytobrush. RESULTS: HSV-1 DNA was detected in vaginal swabs 5 days after the second but not the first inoculation in all three macaques...

Limited longitudinal data exist on the effect of HIV on adipose tissue (AT). We found an increase in CD4+ cells and detectable SHIV-RNA in AT during acute SHIV infection. SHIV-RNA+ cells were rare, suggesting that AT is unlikely to be a major source of productively infected cells in SHIV infection.

Hallmarks of SIV infection are early depletion of gut CD4 T cells and diminished intestinal integrity. Comprehensive studies on colon biopsies of SIV-infected macaques efficiently controlling infection revealed that in contrast to viremic and failing controllers, elite controllers show preserved CD4 T cells, and low viral load, apoptosis, and inflammation.
