EFFECT OF DIPOTASSIUM ETHYLENEDIAMINETETRAACETIC ACID AND LITHIUM HEPARIN ANTICOAGULANT ON HEMATOLOGIC VALUES IN THE BEARDED DRAGON () IN A CLINICAL SETTING.

Anticoagulant choice can have significant effect on complete blood counts of reptiles and has not been reported in bearded dragons (). Whole blood was collected from 14 captive individuals and aliquoted into separate blood tubes containing dipotassium ethylenediaminetetraacetic acid (EDTA) and lithium heparin. Samples were shipped and processed within 24 h.

Polycystic ovarian disease in aquarium-managed cownose rays Rhinoptera bonasus.

Significant knowledge gaps remain in our understanding of the reproductive physiology and diseases of elasmobranchs. The objective of this work is to describe the clinical, imaging, and pathologic findings associated with polycystic ovaries in cownose rays housed in public aquariums. Ten adult female cownose rays Rhinoptera bonasus housed in 4 public aquariums presented with variable nonspecific (lethargy, anorexia, cutaneous discoloration) or no clinical signs.

Postprandial effects following a semielemental critical-care diet lead to changes in uric acid, bile acids, and glucose in the central bearded dragon (Pogona vitticeps).

Objective: To assess the prandial effects of a semielemental diet on plasma uric acid, bile acid, and glucose concentrations in the central bearded dragon (Pogona vitticeps).

Animals: 13 healthy adult male bearded dragons.

Methods: Following a 72-hour fasting period, blood was collected to measure preprandial uric acid, bile acid, and glucose concentrations.

Testosterone identifies hatchling sex for Mojave desert tortoises (Gopherus agassizii).

The threatened Mojave desert tortoise (Gopherus agassizii) exhibits temperature-dependent sex determination, and individuals appear externally sexually monomorphic until sexual maturity. A non-surgical sex identification method that is suitable for a single in situ encounter with hatchlings is essential for minimizing handling of wild animals. We tested (1) whether plasma testosterone quantified by enzyme-linked immunosorbent assay differentiated males from females in 0-3 month old captive hatchlings, and (2) whether an injection of follicle-stimulating hormone (FSH) differentially elevates testosterone in male hatchlings to aid in identifying sex.

Use of computed tomography and magnetic resonance imaging to assess a case of spinal injury in a Showa koi Cyprinus carpio.

Objective: A privately owned, 4-year-old female Showa koi (ornamental variant of Common Carp Cyprinus carpio) was presented for erratic swimming, air gasping, water spitting, and abnormal orientation in the water column. Initial physical examination revealed an obese patient with no external abnormalities except a small plaque localized to filaments on a right gill hemibranch.

Methods: The fish was anesthetized using AQUI-S 20E (10% eugenol solution) at 50 mg/L to facilitate diagnostic evaluation.

MRI of the live fish brain at 3 Tesla: Feasibility, technique and interspecies anatomic variations.

Advances in aquatic animal medicine and continued growth of the fish hobbyist and aquaculture communities have led to a developing interest in antemortem diagnostic imaging of aquatic species. The aims of this prospective, pilot study were to determine whether advanced neuroimaging can be safely achieved in live fish using clinically available equipment, to optimize imaging parameters, and to develop a comparative MRI atlas of a few fish species of economic or research value. Two each of channel catfish (Ictalurus punctatus), koi (Cyprinus rubrofuscus), and grass carp (Ctenopharyngodon idella) of at least 30 cm in length were individually anesthetized for 3 Tesla (3T) magnetic resonance imaging (MRI) of the brain.

ANALYSIS OF SERUM PROTEINS IN HEALTHY GIANT PANDAS () UNDER MANAGED CARE.

Electrophoresis is a practical diagnostic tool for the identification of changes in serum protein fractions, which can be associated with a variety of diseases. Protein electrophoresis studies in Ursidae are limited, and currently no published fraction values are available for the giant panda (). The aim of this study was to describe the serum protein fractions in the giant panda using both capillary zone electrophoresis (CZE) and standard agarose gel electrophoresis (AGE) techniques.

Respiratory Diseases of Snakes.

Respiratory abnormalities in snakes are a common clinical presentation in zoologic medical practice. There are often compounding issues involving translocation and substandard husbandry that can predispose to infectious and noninfectious causes of respiratory disease. Endoscopic evaluation of the respiratory tract and the collection of biopsies for histopathology and microbiology is preferred but may only be available from the specialist.

COMPARISON OF PROTEIN ELECTROPHORESIS AND BIOCHEMICAL ANALYSIS FOR THE QUANTIFICATION OF PLASMA ALBUMIN IN HEALTHY BEARDED DRAGONS ().

While electrophoresis is considered the standard method for evaluation of protein concentrations as a result of its direct measurement, albumin is often quantified with biochemical assays. Many laboratory-based chemistry analyzers and clinic-based point-of-care analyzers use the dye bromocresol green (BCG) for the quantitation of albumin. Several studies have shown that albumin concentrations obtained by the standard (BCG) dye-binding method are significantly different from those obtained by protein electrophoresis in avian species and chelonia.

Computed tomographic and ultrasonographic diagnosis with successful excision of a lipoma in a shusui koi .

Case Description: A client-owned 12-year-old 10.3-kg (22.7-lb) female shusui koi () was evaluated because of an ulcerated mass on the left body wall, hyporexia, and decreased activity.

Mandibular squamous cell carcinoma in 2 psittacines.

A unilateral, malformed gnathotheca in a green-winged macaw () was managed for 16 mo with periodic beak trims. Biopsy of the affected beak did not identify an underlying cause; however, at postmortem examination, a densely cellular neoplasm invaded the mandible from the beak, dissecting and effacing the cortex and trabecular bone and inciting periosteal proliferation. There was no evidence of metastasis.

Technological Advances in Exotic Pet Anesthesia and Analgesia.

Even when performed by skilled operators, locating the nerves can be challenging in small exotic pets; in such cases, the use of an electrical nerve stimulator may be useful to confirm the correct identification of the target nerve. Exotic animal anesthesia and analgesia have dramatically progressed over the past decade and continue to do so as more research and technologies develop. Technological advancements such as airway devices, endoscopic intubation techniques, positive intermittent pressure ventilators, and invasive and noninvasive blood pressure monitors have played a significant role in improving patient safety and the anesthetic outcomes of exotic animals.

Effects of intravenous administration of lidocaine and buprenorphine on gastrointestinal tract motility and signs of pain in New Zealand White rabbits after ovariohysterectomy.

OBJECTIVE To compare analgesic and gastrointestinal effects of lidocaine and buprenorphine administered to rabbits undergoing ovariohysterectomy. ANIMALS Fourteen 12-month-old female New Zealand White rabbits. PROCEDURES Rabbits were assigned to 2 treatment groups (7 rabbits/group).

Ameloblastoma in a wild black rat snake (Pantherophis alleghaniensis).

Reports of neoplasia in captive reptiles are becoming more frequent; however, there is still scarce knowledge of the occurrence of neoplasia in wild reptiles. A wild black rat snake (Pantherophis alleghaniensis) was presented to the Zoological Medicine service of the University of Georgia's Veterinary Teaching Hospital with a 3 cm in diameter solid mandibular mass that was partially ulcerated. Radiographically, the mass was radiopaque with small bone spicules and partial osteolysis of the adjacent mandible.
