Extractive industries can have significant impacts on ecosystems through loss of habitat, degradation of water quality, and direct impact on floral and faunal biodiversity. When operations are located in sensitive regions with high biodiversity containing endangered or threatened species, it is possible to minimize impact on the environment by developing programs to scientifically monitor the impact on resident flora and fauna species in the early phases of operation so that effects can be mitigated whenever possible...

A renal tubular cystadenoma was diagnosed in a 14-yr-old male African lion (Panthera leo). During a routine health evaluation, a left renal mass was identified via physical examination, radiographs, and abdominal ultrasonography. The mass was 30 × 15 cm in size and had a thin capsule with central hypoechoic fluid, suggestive of a perirenal cyst. An exploratory celiotomy with partial nephrectomy was performed without complications. Histologically, the tumor was characterized by a thick fibrous capsule surrounding multiple, variable-sized cysts that markedly compressed the adjacent fibrotic and atrophied renal cortex...

The aim of this study was to determine if ferritin is a reliable biomarker of iron overload disorder (IOD) progression and hemochromatosis in the Sumatran rhinoceros (Dicerorhinus sumatrensis) by developing a species-specific ferritin assay and testing historically banked samples collected from rhinos that did and did not die of hemochromatosis. Ferritin extracted from Sumatran rhino liver tissue was used to generate antibodies for the Enzyme Immunoassay. Historically banked Sumatran rhino serum samples (n = 298) obtained from six rhinos in US zoos (n = 290); five rhinos at the Sumatran Rhino Conservation Centre in Sungai Dusun, Malaysia (n = 5); and two rhinos in Sabah, Malaysia (n = 3) were analyzed for ferritin concentrations...

An 11-yr-old dromedary camel (Camelus dromedarius) at a zoo in south Florida presented with diarrhea while being treated with enrofloxacin and dexamethasone for a chronic skin condition. Three weeks after initiation of therapy with dexamethasone, the camel developed diarrhea, which worsened despite treatment with antibiotics. The animal became increasingly debilitated, developed hemorrhagic diarrhea, declined rapidly over the next 3 days, and died despite aggressive fluid therapy and supportive care. Histologic examination revealed intralesional protozoal tissue cysts consistent with Toxoplasma gondii in the intestines, lungs, and liver, as well as lymphoid depletion of the spleen suggesting immunosuppression...

Reference intervals for diagnostic tests are vitally important for clinical decision making. Despite the popularity of pet goldfish (Carassius auratus), reference intervals have not been generated for routine biochemistry panel analytes in this species. This study establishes de novo reference intervals for packed cell volume and total solids, using 47 apparently healthy immature goldfish, and for 11 common chemistry panel analytes (albumin, aspartate aminotransferase, calcium, creatine kinase, globulin, blood glucose, sodium, potassium, phosphorous, total protein, and uric acid) using 39 immature goldfish...

Between 2006 and 2015, a high incidence of dilated cardiomyopathy (DCM) was diagnosed in a captive population of banded mongooses (Mungos mungo) at Chester Zoo, United Kingdom. The aim of this study was to characterize DCM in these mongooses in order to raise awareness of this condition and help inform management and clinical decisions. Prospective clinical assessments, including echocardiography, radiography, and cardiac biomarkers, were carried out in four mongooses remaining in the collection. Radiographs from 15 mature mongooses were reviewed and cardiac size and metrics assessed...

Acute-phase proteins (APPs) are utilized to detect early inflammation in many domestic and nondomestic species, but variability exists between species and inflammatory diseases as to which APPs are most useful. Stranded juvenile northern elephant seals (NESs; Mirounga angustirostris) undergoing rehabilitation at the Marine Mammal Center experience high mortality rates due to severe arteritis caused by the lungworm, Otostrongylus circumlitis (OC), and there are currently no effective antemortem diagnostic tools for this disease...

In 2015, three psittacines were presented within 30 days, each with differing clinical signs and patient histories. A 13-yr-old male eclectus parrot (Eclectus roratus) was presented for weakness, depression, and acute anorexia. On presentation it was determined to have a heart murmur, severely elevated white blood cell count (93.9 10(3)/μl) with a left shift (2.8 10(3)/μl bands), and anemia (30%). Severe hepatomegaly was noted on radiographs, ultrasonography, and computed tomography. A cytological sample of the liver obtained through a fine needle aspirate revealed intracellular acid-fast bacilli identified as Mycobacterium avium...

Ulcerative skin lesions were observed in two captive adult female hippos (Hippopotamus amphibius) from a zoological collection. Lesions appeared as cracking, peeling, or vesicles of the skin affecting the lateral and ventral aspects of the neck, limbs, thorax, and abdomen, dorsum, toes, and perineal region. Some lesions drained blood, serum, or purulent material. Histologic evaluation of sloughed skin consisted of deep dermal collagen with bacterial cellulitis and vasculitis and superficial fungal colonization...

This manuscript describes an outbreak of fatal toxoplasmosis in wallabies. Ten adult red necked wallabies (Macropus rufogriseus) were imported from New Zealand to the Virginia Zoo. Agglutination testing upon admission into quarantine showed all animals to be negative for antibodies to Toxoplasma gondii. Nine of these wallabies died from acute toxoplasmosis within 59-565 (average 224) days after being moved onto exhibit. Clinical signs included lethargy, diarrhea, tachypnea, and ataxia that progressed rapidly; death without premonitory signs occurred in one case...

Captive rearing programs have been initiated to save the European common spadefoot (Pelobates fuscus), a toad species in the family of Pelobatidae, from extinction in The Netherlands. Evaluating whether this species needs ultraviolet B (UVB) radiation and/or dietary supplementation for healthy bone development is crucial for its captive management and related conservation efforts. The bone mineralization in the femurs and the thickest part of the parietal bone of the skulls of European common spadefoots (n = 51) was measured in Hounsfield units (HUs) by computed tomography...

Ultraviolet B radiation is recommended for captive reptiles to stimulate production of adequate levels of vitamin D; however, little is known regarding the vitamin D status in many free-ranging populations. Current reference ranges for vitamin D in eastern box turtles have not yet been established. Sixty free-ranging eastern box turtles (Terrapene carolina carolina) from two well-studied populations in Illinois (n = 24) and Tennessee (n = 36) were assayed for plasma vitamin D concentration in 2014. There were no significant differences in concentrations between individuals in Illinois (mean: 117...

: Abnormal inter- and intraspecies aggression, perceived to be anxiety related, was identified in two male red-necked wallabies (Macropus rufogriseus) housed within a zoo. Aggressive episodes were directed at conspecifics, other exhibit animals, and, in one case, human caretakers. The clinical use of oral fluoxetine (0.5 mg/kg po bid) for a period of approximately 4 mo was effective in eliminating aggression towards humans and other animals in these two individuals. There was no evidence of recrudescence of aggression in either case following discontinuation of therapy for up to 3 yr posttreatment...

To investigate the pharmacokinetics of the nonsteroidal anti-inflammatory drug (NSAID) piroxicam in cranes, three brolgas (Antigone rubicunda) were administered piroxicam as a single oral dose at 0.5 mg/kg and 1.0 mg/kg during separate trials. Serial blood samples were collected for quantification of piroxicam in plasma. Piroxicam was readily absorbed at both dosages, and no adverse effects were observed. Plasma concentrations peaked at 3.67 hr with a concentration of 4.00 μg/ml for the lower dosage, and at 0...
