  Langur alphaherpesvirus (HVL), a provisionally named alphaherpesvirus in the Simplexvirus genus, was first identified in 1991 at the Bronx Zoo in wild-origin silvered langurs ( Trachypithecus cristatus) and their descendants. HVL is closely related to B virus ( Macacine alphaherpesvirus 1) based on serologic and genetic data, but its natural history and zoonotic potential remain unknown. A cohort study was undertaken to describe the epidemiology, clinical impact, and potential management implications of this virus in a naturally infected, zoo-based population of silvered langurs...

  A 9-yr-old, entire female captive rock hyrax ( Procavia capensis) was presented with a 1-wk history of sialorrhea. On clinical examination, a mass was identified, encompassing the rostral mandible and intermandibular area, with associated mucosal ulceration, marked gingival recession, and loosening or loss of adjacent teeth. Skull radiography and cytology of fine-needle aspirates of the mass were suggestive of squamous cell carcinoma. Based on a suspected poor prognosis, the animal was humanely euthanized...

  Acute-phase reactants indicate inflammation and are increasingly used in veterinary medicine to indicate and to monitor progression of disease. Hemostasis and inflammation have interconnected pathophysiologic pathways and influence each other on different levels. This study established observed normal ranges for acute-phase reactants and for coagulation and thromboelastographic (TEG) parameters in 49 dromedary camels ( Camelus dromedarius) and assessed the response to chronic and acute inflammation. Chronically infected animals suffering from lymph abscessation due to Corynebacterium spp...

  Animal welfare, conservation, and stress assessment are all critical components of species survival. As organisms experience stressors, they accumulate physiologic dysregulation, leading to multiple negative health outcomes. This brief review suggests measuring the degree of stress-induced damage, known as allostatic load, and then using allostatic load to evaluate changes implemented to improve animal welfare and conservation efforts. Over the past two decades, human clinical research has developed multiple allostatic load indices constructed from composites of neuroendocrine, cardiovascular, metabolic, and immune biomarkers...

  This study presents the clinical findings, treatment results, and gross pathology of Trueperella pyogenes-associated interdigital necrobacillosis in captive goitered gazelles ( Gazella subgutturosa). Four male and two female gazelles presented with weight loss, front limb swelling, and persistent lameness despite antibiotic treatment. The animals were reluctant to bear weight on the affected limbs, and the diagnosis of interdigital necrobacillosis was made based on physical exam, bacteriologic evaluation, and radiographic imaging...

Katherine Cassady, John M Cullen, Cathy V Williams
  Coquerel's sifakas ( Propithecus coquereli) are diurnal, folivorous lemurs native to Madagascar and one of only two members of the genus Propithecus currently housed in human care settings outside of Madagascar. This species has a lifespan of approximately 30 yr but minimal information exists regarding morbidity and mortality in human care settings. In this retrospective study, medical records, postmortem exam, and autopsy reports from 56 animals housed at the Duke Lemur Center from 1990 to 2015 were evaluated...

  Brazil has a large variety of wild animal species, but limited data are available on the occurrence of Brucella abortus and Leptospira spp. antibodies in these animals. Sera from 141 captive mammals belonging to 11 different species from the Northern and Northeastern regions of Brazil were screened. Antibodies against B. abortus and Leptospira spp. (24 live serovars) were investigated using the Rose Bengal plate and microscopic agglutination tests, respectively. Associations between the age, gender, and place of captivity were analyzed using the Pearson chi-square or the Fisher exact test...

  A 3-yr-old spayed female coyote ( Canis latrans) developed clinical signs of exertional myopathy after fighting with a conspecific. A diagnosis of exertional myopathy was made based on physical examination findings, probable myoglobinuria, and elevations in serum creatinine kinase activity, alanine aminotransferase activity, and potassium concentration. Dantrolene, a hydantoin analog, as well as supportive and symptomatic therapies, was used to successfully treat exertional myopathy. This is the first reported use of dantrolene in wildlife or zoo animals...

  This study aimed to assess joint angle values in the forelimbs and hind limbs of crab-eating foxes ( Cerdocyon thous) using a conventional manual goniometer. Nine captive crab-eating foxes, aged over 1 yr old, weighing from 5.9 to 7.5 kg were used. The maximum flexion and maximum extension of the shoulder, elbow, carpal, hip, stifle, and tarsal joints were measured. The range of motion was determined through the difference between the maximum flexion and the maximum extension. There was no significant difference between the right and left sides in the goniometric measurements...

  A 2-mo-old Vancouver Island marmot ( Marmota vancouverensis), housed at a quarantined breeding facility, presented for acute obtundation and vestibular ataxia. Physical examination revealed poor growth compared with littermates, poor nutritional condition, and mild dehydration. The animal's condition deteriorated over 24 hr, and it was euthanized following the development of generalized seizures. No gross abnormalities were observed upon postmortem evaluation. Histologic evaluation revealed severe, multifocal, granulomatous and lymphoplasmacytic meningoencephalomyelitis and interstitial nephritis, with intralesional, intracytoplasmic spore-filled, parasitophorous vacuoles and segmental, multi-organ, fibrinoid vasculitis (disseminated encephalitozoonosis)...

  A chytridiomycosis outbreak from Batrachochytrium dendrobatidis ( Bd) in a mixed-species plethodontid salamander exhibit resulted in four green salamander ( Aneides aeneus) deaths. One green salamander died before treatment, and three died during treatment with daily 0.005% itraconazole baths. All salamanders had evidence of severe Bd infections via cytology, histopathology, and/or polymerase chain reaction (PCR) at the time of death. Ten long-tailed salamanders ( Eurycea longicauda) and one two-lined salamander ( Eurycea bislineata) that shared the enclosure were initially negative for Bd on quantitative PCR but were prophylactically treated with daily 0...

  Supraorbital salt-excreting glands are present in at least 10 avian orders and are largest in marine species, including penguins. Diseases of the avian salt gland have been described infrequently. From September 2015, five captive northern rockhopper penguins ( Eudyptes moseleyi) were presented over a 6-wk period for unilateral or bilateral supraorbital swellings. In September 2016, two cases recurred and two additional cases were identified. Histopathology demonstrated salt gland adenitis with extensive squamous metaplasia...

Jessye Wojtusik, Terri L Roth
  Iron overload disorder (IOD) can lead to organ dysfunction and may exacerbate other diseases in the critically endangered black rhinoceros ( Diceros bicornis). It is important to develop methods for monitoring the progression of iron storage (hemosiderosis), diagnosing the disease, and evaluating treatments in this species. Traditionally, an equine enzyme immunoassay (EIA) was used to measure rhinoceros ferritin, a serum protein correlated to iron stores. The goal of this study was to validate a rhinoceros-specific assay and investigate factors potentially associated with ferritin concentrations in black rhinoceros...

  Despite the growing knowledge and literature on primate medicine, assessment and treatment of behavioral abnormalities in nonhuman primates (NHPs) is an underdeveloped field. There is ample evidence for similarity between humans and great apes, including basic neurologic physiology and emotional processes, and no substantial argument exists against a concept of continuity for abnormal conditions in NHPs that emerge in response to adverse experiences, akin to human psychopathology. NHPs have served as models for human psychopathologies for many decades, but the acquired knowledge has only hesitantly been applied to primates themselves...

  A captive-born adult female Nilgiri langur ( Semnopithecus johnii) developed an edematous swelling of the left thigh and a firm mass around the right ankle joint. The animal also suffered from lethargy and anorexia and was euthanized because of poor general condition. Necropsy revealed that the skeletal muscle of the left thigh had been replaced by a multilocular cystic mass containing numerous sand-grain-sized whitish structures. Small cysts were also present in the lung and the myocardium. The mass of the right ankle joint was histologically consistent with a myxosarcoma...

  The aim of the present study is to determine the basal parameters in opossums ( Didelphis virginiana) during physical examination in Yucatan, Mexico. Sixty-six opossums were captured and manually handled for physical examinations. Sex, age, cardiac and respiratory rate, body temperature, pulse, mucous membranes, capillary refill time, hydration, size of superficial lymph nodes, mental status, and body condition were evaluated. Also, comparisons between rectal and auricular temperatures were performed. The means of physiological parameters obtained were: cardiac frequency 146 beats per minute (95% confidence interval [CI]: 138...

  The Maryland Zoo in Baltimore is home to the largest captive assurance population of the critically endangered Panamanian golden frog ( Atelopus zeteki). With the ongoing extinction that is occurring worldwide in amphibians, the need for amphibian captive assurance populations is growing, and few mortality reviews on amphibian species exist. Necropsy and histopathologic examination of animals that die in captivity can help identify population-level disease problems, direct research needs in amphibian medicine and husbandry, and improve the success of captive breeding programs...

  An outbreak of HPAIV H5N1 in Nakhon Sawan province, Thailand, in 2004 caused sporadic deaths of Asian openbill storks ( Anastomus oscitans). An investigation was undertaken to determine if this virus occurs and circulates in wild birds in Nakhon Sawan province. Following the outbreak, a widespread serosurvey was conducted using the hemagglutination inhibition assay and microneutralization assay to detect antibodies against AIV H5. From 2007 to 2014, blood was collected from a total of 753 wild birds, representing 10 orders and 44 species...

Andrea L Goodnight, Sherry Cox
  Meloxicam, a COX-2 selective nonsteroidal anti-inflammatory medication, has been used in many exotic animals at doses extrapolated from domestic animal pharmacokinetic and pharmacodynamic studies. Increasing evidence suggests that significant species differences exist in meloxicam metabolism. Because of this, dose extrapolation from domestic animals may not be appropriate for exotic species. The objective of this study was to investigate the pharmacokinetics of meloxicam in a population of male Malayan flying foxes, Pteropus vampyrus, following a single oral dose of 0...
