PROSPECTIVE POSTMORTEM ASSESSMENT OF THE INCIDENCE OF MAMMARY NEOPLASIA IN CHIMPANZEES ().

When evaluating the last 25 yr of morbidity and mortality from adult chimpanzees managed within the Association of Zoo and Aquarium Chimpanzee Species Survival Plan® for North American zoos, only two female chimpanzees were diagnosed with mammary neoplasia: one incidentally antemortem and one with a terminal metastatic neoplasia. When comparing this observation of prevalence of mammary neoplasia to humans, a substantial disparity is apparent. Mammary neoplasia is the second most common cancer in adult female humans, with a lifetime risk of 1:8 in the United States.

PHARMACOKINETICS OF ORAL FLUNIXIN MEGLUMINE, MELOXICAM, OR GABAPENTIN IN THREE BLACK RHINOCEROS ().

Pharmacokinetics of single, separate doses of IV flunixin meglumine (1 mg/kg), IV meloxicam (0.5 mg/kg), oral flunixin meglumine (1 mg/kg), oral meloxicam (1 mg/kg), and oral gabapentin (15 mg/kg) in three adult black rhinoceroses () were determined from serial blood collection made over 72 h. The concentration versus time profiles were analyzed for each drug and route in each individual rhinoceros, and individual pharmacokinetic parameters were calculated for each medication administered.

HYPOCOAGULABILITY EFFECT OF ADEQUAN IN DOMESTIC CHICKENS () AND CHILEAN FLAMINGOS ().

Effective management of articular injuries in avian species is a known and frequent challenge. Potential treatments include many domestic animal therapeutics, such as Adequan®, which is used widely in dogs and horses. However, clinical reports have described hemorrhagic diatheses in a variety of avian species treated with varying doses and administration frequency of Adequan.

Shell Lesions Associated With Infection in Freshwater Aquatic Turtles.

A newly described onygenalean fungus, , has been isolated from ulcerative shell and skin lesions of freshwater aquatic chelonians. To investigate the shell lesions associated with infection and determine if any lesional features were unique to . , tissues from turtles housed in zoological institutions ( = 45) in the United States and free-living turtles ( = 5) submitted for diagnostic biopsy or necropsy were examined.

Probable Enalapril Hepatotoxicity in a 13-Year-Old Male Western Lowland Gorilla: Pharmacologic Risks and Vigilance.

A 13-year-old male Western lowland gorilla presented acutely with a precipitous decline in health status from liver disease. Through diagnostic assessment, including serum chemistries and advanced imaging, it was diagnosed with probable hepatotoxicity resulting from its prescribed medication, enalapril. As one of several angiotensin converting enzyme inhibitors (ACE-I) available to zoo veterinarians, enalapril had been administered for treatment of mild ventricular hypertrophy diagnosed during routine examination 2.

PHARMACOKINETICS OF A SINGLE ORAL DOSE OF FLUNIXIN MEGLUMINE IN THE WHITE RHINOCEROS ().

Flunixin meglumine, a nonsteroidal anti-inflammatory medication, has been used in rhinoceros species at doses extrapolated from domestic animals. There is increasing evidence to suggest significant variations exist in metabolism of drugs in exotic species. Due to the differences in drug metabolism, dose extrapolation from domestic animals may not be appropriate for exotic species.

Novel Herpesvirus Associated With Oropharyngeal Squamous Cell Carcinoma in Smooth Green Snakes ().

During a 19-month period, 5 smooth green snakes () maintained as an ex situ conservation colony presented with rapid clinical progression of locally invasive oropharyngeal squamous cell carcinoma. All 5 originated from the same wild source and were housed together or in close proximity. An infectious cause was considered likely, and nested conventional polymerase chain reaction (PCR) and in situ hybridization confirmed the presence of a novel alphaherpesvirus, Opheodrys herpesvirus 1, in the neoplastic tissue in 4 of the 5 snakes.

ORONASAL SQUAMOUS CELL CARCINOMAS IN FRANÇOIS' LANGURS (TRACHYPITHECUS FRANCOISI).

Squamous cell carcinomas (SCCs) are common oronasal tumors in nonhuman primates. In this study, 11 cases of oronasal SCC in François' langurs ( Trachypithecus francoisi ) are described. Five initial cases were discovered on review of the North American François' langur studbook, with a potential familial pattern observed.

Plasma Concentrations of Fentanyl Achieved With Transdermal Application in Chickens.

Providing appropriate analgesia is an important concern in any species. Fentanyl, a μ-receptor specific opioid, use is common in mammalian species but has been incompletely evaluated for this purpose in avian species. Transdermal fentanyl patches were applied to domestic chickens (n = 10) of varying breeds for 72 hours.

RETROSPECTIVE ANALYSIS OF ADULT-ONSET CARDIAC DISEASE IN FRANÇOIS' LANGURS (TRACHYPITHECUS FRANCOISI) HOUSED IN U.S. ZOOS.

Cardiac disease is a common condition in captive primates, and multiple cases in François' langurs ( Trachypithecus francoisi ) were noted on review of the Species Survival Plan studbook. To determine the prevalence of cardiac disease in this species, surveys were distributed to current and previous holding institutions (n = 23) for the U.S.

PROSPECTIVE POPULATION MANAGEMENT FOR HEPATITIS B IN THE CHIMPANZEE (PAN TROGLODYTES) SSP® POPULATION.

Hepatitis B virus causes horizontally transmitted infectious hepatopathy of primates and may progress to hepatocellular carcinoma. Historically, a small number of chimpanzees ( Pan troglodytes ) living in accredited North American zoos have been confirmed with positive hepatitis B serology consistent with exposure. However, the overall status for this population and the interpretation of these individual test results have not been established previously.

Detection and Management of Air Sac Trematodes (Szidatitrema Species) in Captive Multispecies Avian Exhibits.

From 2 exhibits in a zoological collection, 2 juvenile fairy bluebirds ( Irena puella ) and 1 adult blue-grey tanager (Thraupis episcopus) died within 3 months of one another. The cause of death was attributed to air sac trematodes, which were identified as Szidatitrema species based on morphology of adult trematodes and miracidia isolated from a snail intermediate host. To determine the extent of trematodiasis in the collection, individual exhibits within the same building as the original presenting cases were assessed, with birds representing 27 avian species from 9 orders.

RETROSPECTIVE ANALYSIS OF MORTALITY IN THE NORTH AMERICAN CAPTIVE RED PANDA (AILURUS FULGENS) POPULATION, 1992-2012.

Red pandas ( Ailurus fulgens ) are managed as captive populations in both North America and Europe. Regular review of pathology reports is a useful tool for developing veterinary care and husbandry strategies for such populations. Though thorough pathology reviews have been conducted for the European studbook, the North American population has not been reviewed similarly until now.

EVALUATION OF THYROID HORMONES AND AS INFLUENCED BY TREATMENT WITH DESLORELIN IN PALLAS' CATS (OTOCOLOBUS (FELIS) MANUL).

Thyroid hormones regulate a variety of physiologic functions including metabolism, growth, and reproductive cycling, and these other hormones can impact the thyroid function via the hypothalamic-pituitary axis. For instance, the gonadotropin-releasing hormone agonist, deslorelin, used in nondomestic carnivores for contraception and behavioral control, down-regulates reproductive hormones through this mechanism and so may impact thyroid function. Due to clinical concerns of hypothyroidism in a bachelor group of adult male Pallas' cats (Otocolobus (Felis) manul) which also had deslorelin implants, serum samples from treated captive (n = 8) individuals, untreated captive (n = 25), and free-ranging (n = 9) individuals were analyzed for thyroid hormone concentrations.

EXTRACORPOREAL SHOCK WAVE LITHOTRIPSY AND ENDOSCOPIC URETERAL STENT PLACEMENT IN AN ASIAN SMALL-CLAWED OTTER (AONYX CINEREA) WITH NEPHROLITHIASIS.

Urolithiasis is a significant disease concern in Asian small-clawed otters (Aonyx cinerea), with over 60% of captive animals affected. Bilateral ureteral stent placement, using endoscopic and fluoroscopic guidance, and extracorporeal shock wave lithotripsy (ESWL) were performed as salvage procedures in a 13-yr-old intact female Asian small-clawed otter following a 7-yr history of nephrolithiasis and progressive renal insufficiency. Following the procedure, radiographs revealed a slight shifting of urolith position, although a decrease in urolith mass was not observed.
