Cardiomyopathy is suggested to be a relatively common disease condition in prairie dogs; however, there are no reports of normal cardiac echosonography and radiology in the prairie dog ( Cynomys spp.). The objective of this study was to report the ultrasonographic and radiographic measurements of the heart, and plasma troponin concentration in captive healthy anesthetized black-tailed prairie dogs ( Cynomys ludovicianus ). Zoo-kept prairie dogs with no signs of cardiac disease (n = 17) were evaluated. Each animal was anesthetized with isoflurane via face mask and a complete clinical assessment was performed, including complete blood cell count and plasma biochemistry, urinalysis, blood gasses, plasma troponin concentration, three-view whole body radiography, and echocardiogram...

The sulcata or African spurred tortoise (Centrochelys sulcata) is a large tortoise species that is commonly kept in zoologic collections and as a pet. The objectives of this study were to establish reference intervals for selected biochemical analytes in clinically healthy captive sulcata tortoises and to evaluate the impact of blood sampling site and sex. Blood samples were collected from 60 tortoises from either the dorsal coccygeal (tail) vein or the subcarapacial venous plexus based on their body size. The packed cell volume and refractometric total solids (TS) were determined...

A 13-yr-old female binturong ( Arctictis binturong ) presented with a 1 wk history of decreased appetite. The animal was thin, with hypercalcemia (calcium 12.2 mg/dl). A right renal mass was identified on ultrasound and removed via nephrectomy. Histopathology indicated a renal adenocarcinoma. Treatment with toceranib phosphate, a tyrosine-kinase inhibitor, was initiated and well tolerated by the animal. Four months after initial diagnosis radiographs indicated metastases to the lungs and the animal was euthanized...

A privately owned, 2-yr-old, 600-kg, intact male white rhinoceros presented with a progressive lameness of the left front limb of 8-mo duration with a focal swelling situated over the dorsoproximal aspect of third metacarpophalangeal joint. Radiographs of the affected limb showed a 28 mm × 26 mm exostosis at the dorsodistal third metacarpal bone. Surgical removal of the exostosis was performed and histopathologic examination confirmed a solitary osteochondroma. A follow-up examination 1 yr after surgical removal revealed total abolishment of the left front limb lameness...

Holly J Holman, Katherine Gailbreath
An 8-yr-old nulliparous, female rock hyrax ( Procavia capensis ) had intermittent mucoid to bloody discharge late winter-early spring for two consecutive years. Fragments of necrotic tissue, suspected to be vaginal or rectal in origin, were passed on two occasions. Physical examination, radiographs, and ultrasound did not identify the source of the tissue. Exploratory laparotomy and ovariohysterectomy were performed. On histopathology, a diagnosis of adenomyosis with a uterine polyp was made. Postsurgical complications included incisional infection and renal compromise that were medically managed and resolved...

:  A series of eight cases of intestinal adenocarcinoma in Amazon milk frog (Trachycephalus resinifictrix) is described. All cases presented with signs of inappetence and weight loss, and evidence of large intestinal distention on gross postmortem, with six of the eight cases showing a grossly visible large intestinal mass. Histologic examination identified the mass as an intestinal adenocarcinoma in all cases. No specific etiologic agent could be identified. This is the first report of neoplasia in the Amazon milk frog, and the first reported series of amphibian gastrointestinal neoplasia...

The agouti ( Dasyprocta leporina ) is a New World wild rodent hunted for its meat in Trinidad and other Latin American countries. Studies on agouti under captive conditions have yielded some data on health-related aspects, but relatively very little is known about their wild counterparts. The environment of the agouti can influence the microflora and parasites harbored by the animals, which may contain zoonotic pathogens. Here, the microflora found on the nasal mucosa and sections of the intestinal tract and endoparasites of freshly shot agouti from various areas of Trinidad are described...

A 19-yr-old captive male Syrian bear ( Ursus arctos syriacus) presented with a right hind limb lameness that progressed to nonambulatory paraparesis over the course of 2 wk. When night enclosure confinement and a short course of glucocorticoids and antibiotics did not lead to improvement, radiographs were performed, followed by cerebrospinal fluid analysis and myelography, revealing a dynamic spinal cord compression at the level of T2-T3. Dorsal laminectomy of both T2 and T3 was performed to allow decompression...

The purple-spined sea urchin ( Arbacia punctulata ) is commonly found in shallow waters of the western Atlantic Ocean from the New England area of the United States to the Caribbean. Sea urchins play a major role in ocean ecology, echinoculture, and biomedical research. Additionally, sea urchins are commonly displayed in public aquaria. Baseline parameters were developed in unanesthetized urchins for righting reflex (time to regain oral recumbency) and spine response time to tactile stimulus. Tricaine methanesulfonate (MS-222) was used to sedate and anesthetize purple-spined sea urchins and assess sedation and anesthetic parameters, including adhesion to and release from a vertical surface, times to loss of response to tactile stimulus and recovery of righting reflex, and qualitative observations of induction of spawning and position of spines and pseudopodia...

Sinusitis is a common finding in avian species; however, it presents unique treatment challenges in ratites. A 6-yr-old male greater rhea ( Rhea americana ) presented acutely with right infraorbital sinus swelling and chemosis. Oral antibiotics were prescribed based on bacterial culture results with incomplete resolution of clinical signs. A computed tomography scan of the skull demonstrated a mixed-density soft tissue mass with extensive destruction of the right nasal bone, hard palate, maxilla, and frontal bone...

Serological tests play an important role in the detection of wildlife diseases. However, while there are many commercial assays and reagents available for domestic species, there is a need to develop efficient serological assays for wildlife. In recent years, marine mammals have represented a wildlife group with emerging infectious diseases, such as influenza, brucellosis, and leptospirosis. However, with the exception of disease-agent-specific assays or functional assays, few reports describe the use of antibody detection assays in marine mammals...

An adult leopard gecko ( Eublepharis macularius ) presented for lethargy, hyporexia, weight loss, decreased passage of waste, and a palpable caudal coelomic mass. Computed tomography showed a heterogeneous hyperattenuating (∼143 Hounsfield units) structure within the right caudal coelom. The distal colon-coprodeum lumen or urinary bladder was hypothesized as the most likely location for the heterogeneous structure. Medical support consisted of warm water and lubricant enema, as well as a heated environment...
