Basic Information Sheet: Virginia Opossum

The Virginia opossum is the only marsupial native to North America. This New World species is correctly called an “opossum” as opposed to the Old World “possum”. This information sheet reviews natural history, conservation status, and taxonomy, as well as a number of clinically relevant information including (but not limited to) diet, housing, behavior, normal physiologic data and anatomy, restraint, preventive medicine, zoonoses, and important medical conditions seen in the opossum.

Client Education Handout 

Care of the Virginia Opossum

The Virginia opossum is the only marsupial native to North America. Although veterinarians are allowed to provide humane care to any injured or orphaned wild animal, it is important to know your state laws as it is illegal to keep a pet opossum in many states. This client education handout reviews the basics of a pet opossum diet, caging, behavior, as well as health concerns.

AEMV-Lafeber Case Report: Pituitary-Dependent Hyperadrenocorticism and Cholangiohepatitis in a Guinea Pig

A 3-year old intact male guinea pig was presented on emergency for suspected bloat and with a history of chronic hair loss. Clinical examination revealed non-pruritic symmetric truncal alopecia, thin skin, severe cachexia, and an abdominal fluid wave. Alkaline phosphatase, alanine transaminase, aspartate aminotransferase, gamma-glutamyl transferase, leukocytes (neutrophils), bilirubin, and serum cortisol were markedly elevated. Abdominal ultrasonography revealed peritoneal effusion, cholestasis, and cholelithiasis. Hyperadrenocorticism was diagnosed based on…

AEMV-Lafeber Case Report: Gastric Dilatation and Volvulus in a Guinea Pig

An adult intact female guinea pig was presented with dysorexia, exhaustion and weight loss. Radiographic and ultrasound findings demonstrated a severe gas dilatation of the stomach, severe gallbladder distension, and abnormalities on the organ topography. On laparotomy, a 180-degree gastric dilatation and volvulus was noticed with a gallbladder obstruction, hepatic lipidosis, and adhesions between the bowels…

AEMV-Lafeber Case Report: Budd-Chiari-Like Syndrome in a Domestic Rabbit

An eleven year old male neutered rex rabbit presented with lethargy and inappetence of two days duration, and an acute episode of vestibular ataxia. Anemia and elevations in plasma alkaline phosphatase and alanine aminotransferase were evident. Abdominal ultrasound revealed questionable, diffuse hepatomegaly. Computed tomography revealed hepatic venous congestion, severe dilation of the pre-hepatic caudal vena cava, and bicavitary effusion, consistent with Budd-Chiari-like syndrome. Turbulent blood flow within the dilated segment of the caudal vena cava was present on spectral Doppler evaluation. Fine needle aspirate and cytology of the liver revealed necrosis with no evidence of infectious organisms…

AEMV-Lafeber Case Report: Multiple Drug Resistant Staphylococcus Infection, Post Spay in a Domestic Rabbit

A female, spayed miniature lop rabbit presented 1-week post spay with marked subcutaneous swelling along the entire length of the surgical incision. Subsequent debridement of the abscess and closure of the incision site was somewhat unsuccessful, with the patient returning for another debridement procedure, after which the wound was left open for continued flushing and debridement. Culture and sensitivity of the purulent material grew a multi-drug resistant Coagulase-positive Staphylococcus.

AEMV-Lafeber Case Report: Hyperthyroidism Treated with Radiation Therapy (I-131) in Two Guinea Pigs

Two guinea pigs suspected of having hyperthyroidism based on weight loss, presence of a cervical mass, and elevated total thyroxine (TT4) levels were confirmed to have active thyroid masses via scintigraphy with Technetium-99 and treated with radioactive iodine therapy (I¹³¹). Both patients responded initially with weight gain and a decrease in the TT4. The purpose of this case series is to describe the use of scintigraphy to aid in confirming a diagnosis of hyperthyroidism, as well as to show the benefits and effectiveness of using radioactive iodine therapy (I¹³¹) to treat hyperthyroidism in guinea pigs in order to provide the best treatment protocol.

AEMV-Lafeber Case Report: Endometrial Venous Aneurysm in a Lionhead Rabbit

A 1-year-old female intact lionhead rabbit was referred for a history of hematuria, bloody vaginal discharge, anorexia, and lethargy unresponsive to antibiotics and anti-inflammatory medications. Based upon physical examination, radiographs and abdominal ultrasonography a uterine mass was suspected. Severe regenerative anemia secondary to blood loss was diagnosed and the rabbit was administered a whole blood transfusion prior to surgical intervention. Abdominal exploratory with ovariohysterectomy revealed…

Capnometry in Exotic Animal Species

Capnometry measures the maximum value of carbon dioxide (CO2) obtained at the end of expiration or end-tidal carbon dioxide (ETCO2). There is good correlation between ETCO2 and arterial CO2 in birds and mammals and capnography can be used as a reliable tool to evaluate the adequacy of ventilation in these species. Capnography can only be used to identify trends in reptiles because of cardiac shunting of blood past the reptilian lungs.

Monitoring Vital Signs in Exotic Animal Species

Even the most steadfast and seasoned veterinary anesthetist can find themselves intimidated by exotic animal patients. Standard veterinary anesthesia monitors are not designed to read the extremely high (or extremely low) heart rates and respiratory rates of some exotic animal patients. Despite these challenges, valuable information can be gathered from monitoring tools as well as hands-on techniques. Essential vital signs, such as heart rate and rhythm, respiratory rate and depth, body temperature, and mucous membrane color should all be evaluated.

Blood Pressure Monitoring in Exotic Animal Species

Arterial blood pressure is a function of heart rate, blood volume, stroke volume, and arterial compliance. Indirect arterial blood pressure is most commonly measured by Doppler ultrasound or non-invasive oscillometric monitors. What are the limitations of indirect blood pressure measurements in exotic animal patients? How is this technique unique in exotic companion mammals when compared to dogs and cats? How is this technique performed in birds and can this procedure be used in reptiles?

Electrocardiography in Exotic Animal Species

Electrocardiography can be used to detect and diagnose arrhythmias and conduction abnormalities, particularly during long-term anesthesia. How are leads attached to exotic animal patients? And what is the normal appearance of normal electrocardiogram tracings in birds or reptiles?

Article 

Pulse Oximetry in Exotic Animal Species

Heart rate and oxygenation should ideally be monitored during every anesthetic event. Patient size can limit the accuracy of pulse oximetry readings in exotic companion mammals and this technique has not been validated in birds or reptiles, however trends during the course of anesthesia can still provide useful clues to patient clinical status.

Understanding Reptile Dental Anatomy: Clinical Applications

Reptile dentition tends to be relatively uniform with a simple, conical shape. Most reptile teeth are loosely attached with the dental attachment most superficial in acrodontic species. Tooth loss and replacement is a normal occurrence in reptile species with pleurodont dentition, which includes snakes, and many lizards. Take special care when handling reptiles with acrodont dentition as teeth will not be replaced when infected or fractured. Additionally, periodontal disease is common in captive lizards with acrodont dentition such as bearded dragons and chameleons. Periodontal disease is an insidious condition. As plaque formation builds and gingivitis worsens, many reptiles will continue to eat. The owner may not observe problems until disease is quite advanced. Feeding lizards an unnatural, soft diet is believed to promote plaque development and the development of periodontal disease.

Sara Ruane, PhD

Sara Ruane is an Assistant Professor at Rutgers University-Newark in the Department of Biological Sciences. Her research is primarily based in reptile systematics and evolution. . The Ruane Lab seeks to simultaneously inform reptile and amphibian systematics while also answering broad, contemporary questions in evolutionary biology. Some of Dr. Ruane’s current research focuses on the phylogenetics of the Malagasy pseudoxyrhophiines, as well as examining undescribed diversity in the poorly known New Guinea snakes. While her interests in herpetology are broad, she primarily focuses on snakes, especially with respect to systematics, phylogenetics, and phylogeography.
