Unique Calcium Metabolism in Zoological Companion Animal Species.

Regardless of species, calcium, vitamin D, and parathyroid hormone physiology are intricately linked. However, there are many unique differences between taxa that may affect husbandry recommendations, common disease processes, and effective treatment. This article aims to provide a basic overview of calcium metabolism and physiology then specifically delve into unique attributes of calcium homeostasis in common zoologic companion animal species.

Proposed grading scheme for inflammatory bowel disease in ferrets and correlation with clinical signs.

Inflammatory bowel disease (IBD) is an idiopathic, chronic, inflammatory disease of the gastrointestinal tract of companion animals, including ferrets (). Clinical signs of IBD are nonspecific, and intestinal biopsies are necessary for a definitive diagnosis. A grading scheme has not been established for ferrets.

Effects of Isoflurane Anesthesia on the Hematologic Values of Rehabilitated Wild Owls.

Isoflurane anesthesia is commonly used for owls when they are being rehabilitated to minimize stress during treatments and procedures, as well as to ensure caretaker safety. However, the effects of isoflurane anesthesia on the hematologic response of owls are not known. To investigate the effects of isoflurane anesthesia on the hematology of owls, 3 phases of investigation were performed on the subject animals: 1) single, short manual- versus single, short isoflurane-restraint episodes (n = 12; 38%); 2) a single, prolonged isoflurane episode (n = 10; 31%); and 3) serial, short isoflurane episodes (n = 10; 31%).

Diseases of the Reptile Renal System.

Renal disease accounts for a considerable amount of morbidity and mortality in reptiles, in part owing to inadequate husbandry practices, such as inappropriate temperature, humidity, and access to water. Inappropriate husbandry practices may lead to subclinical dehydration that can specifically impact the renal system, which relies on vascular perfusion to function. This article aims to highlight urinary pathophysiology and summarize infectious and noninfectious causes of renal disease in reptiles as a guide for differential diagnoses to consider during clinical evaluation.

EVALUATION OF NONINVASIVE OSCILLOMETRIC BLOOD PRESSURE MONITORING IN ANESTHETIZED BENNETT'S WALLABIES ().

The objective of this study was to determine the accuracy of a noninvasive oscillometric method in relation to invasively measured blood pressure in anesthetized Bennett's wallabies () and also to compare the accuracy of two commonly used oscillometric blood pressure monitors (manufactured by Cardell and Datascope). Eleven animals were anesthetized, and each animal was instrumented with an arterial catheter in the right medial metatarsal artery connected to a pressure transducer to obtain invasive measurements of systolic (SAP), diastolic (DAP), and mean (MAP) arterial blood pressure as well as a pressure waveform. A cuff connected to an oscillometric device was placed on the base of the tail for noninvasive measurements.

CHARACTERIZING THE 25-HYDROXYVITAMIN D STATUS OF TWO POPULATIONS OF FREE-RANGING EASTERN BOX TURTLES (TERRAPENE CAROLINA CAROLINA).

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.

COMPARISON OF MEDETOMIDINE-KETAMINE AND BUTORPHANOL-AZAPERONE-MEDETOMIDINE IN CAPTIVE BENNETT'S WALLABIES (MACROPUS RUFOGRISEUS).

The objective of this study was to compare a traditional partially reversible medetomidine-ketamine sedation with a more reversible butorphanol-azaperone-medetomidine combination in Bennett's wallabies ( Macropus rufogriseus ) maintained in a zoological collection. Fourteen animals were divided into two treatment groups. Individuals in group 1 received an intramuscular (i.

Histology and immunohistochemistry of severe inflammatory bowel disease versus lymphoma in the ferret (Mustela putorius furo).

Inflammatory bowel disease (IBD) is a common disorder of ferrets (Mustela putorius furo) that may progress to lymphoma. Although routine histology is used to distinguish between these diseases, misclassifications may occur. Immunohistochemistry (IHC) is commonly used to distinguish between IBD and lymphoma in small animals.

Pharmacokinetics and bioavailability of orbifloxacin oral suspension in New Zealand White rabbits (Oryctolagus cuniculus).

OBJECTIVE To evaluate the pharmacokinetics and bioavailability of 2 doses of orbifloxacin in rabbits. ANIMALS 6 healthy purpose-bred adult female New Zealand White rabbits (Oryctolagus cuniculus). PROCEDURES Each of 3 rabbits received orbifloxacin at either 10 or 20 mg/kg, PO.

Evaluating the clinical and physiological effects of long term ultraviolet B radiation on guinea pigs (Cavia porcellus).

Vitamin D is an important hormone in vertebrates. Most animals acquire this hormone through their diet, secondary to exposure to ultraviolet B (UVB) radiation, or a combination thereof. The objectives for this research were to evaluate the clinical and physiologic effects of artificial UVB light supplementation on guinea pigs (Cavia porcellus) and to evaluate the long-term safety of artificial UVB light supplementation over the course of six months.

Effects of sevoflurane anesthesia on righting reflex and hemolymph gas analysis variables for Chilean rose tarantulas (Grammostola rosea).

Objective: To determine the safety, efficacy, and effects on hemolymph gas analysis variables of sevoflurane anesthesia in Chilean rose tarantulas (Grammostola rosea).

Animals: 12 subadult Chilean rose tarantulas of unknown sex.

Procedures: Spiders were anesthetized in a custom chamber with sevoflurane (5% in oxygen [1.

Bilateral carpal contracture in a neonatal addax (Addax nasomaculatus).

A neonate male addax calf displayed an inability to extend its forelimbs bilaterally (range of motion restricted to 45 degrees-50 degrees on full extension) with resultant inability to stand. Based on examination and radiographs, the congenital defect was attributed to contracted soft tissue structures (joint capsule and/or intercarpal ligaments). Splinting, support of the limbs, and physical therapy resulted in moderate improvement of the angle of contraction (full flexion to approximately 120 degrees on extension at day 10).
