Avian & Exotic

Intubation provides better airway control than a face mask and minimizes the risk of aspiration. This is especially important for complex and prolonged procedures, when complications such as respiratory obstruction and hypoventilation are more likely to occur. Rabbits and rodents are difficult to intubate.

Major indications: Radiology is one of the most important diagnostic exam methods in birds. It is extremely well suited due to the poor specificity of disease symptoms a sick bird shows and especially due to the presence of the airsacs in the coelomic cavity. The air in the body and around the organs is a great contrast material.

Rabbits, chinchillas, and guinea pigs are monogastric, hind-gut fermenters; all have a functional cecum and require a high-fiber diet. Fiber is broken down in the cecum by a variety of microorganisms which are nourished by a constant supply of water and nutrients from the stomach and small intestine.

Exotic animal medicine is an exciting and rapidly growing part of companion animal practice. Exotics represent roughly 25-30% of the companion animal market for veterinary services. Pet owners readily seek out veterinary care for birds, small exotic mammals, reptiles and amphibians.

In this presentation we will discuss the various groupings of parasites seen infesting reptiles & amphibians, how to identify them and thoughts on proper treatment to rid the hosts of these parasites.

In order to use antimicrobial drugs in exotic patients effectively, one has to understand both the basic pharmacokinetics of these drugs, as well as certain key physiological features of the species being treated (e.g. a poikilotherm animal vs. a homeotherm). One mayor problem in the use of antimicrobial drugs approved for dogs and cats in exotic species, is the fact that there is little clinical data available on the use of these drugs in exotic patients.

As the popularity of reptiles has grown, so has the demand for quality veterinary care. Today, reptile medicine represents a viable subset of companion animal practice. Reptiles are stoic and have evolved to mask signs of illness, which makes them a challenge to diagnose and treat. For veterinarians and technicians who are willing to become proficient, however, reptile practice offers many rewards.

Kidney related diseases are a major cause of illness and death in captive lizards. Improper captive husbandry and diet are the most common predisposing causes of chronic renal failure - which is typically seen in adult lizards. Whereas acute onset of renal disease is often due to infectious or toxic causes (Including medications) and appears to effect any age animal and is typically more sporadic in occurrence.

Rabbits, guinea pigs, and chinchillas are all monogastric, hindgut-fermenting herbivores adapted to a course, high-fiber diet. They graze and browse almost continuously, chewing on plant material, gradually wearing their teeth down as a result. To compensate, the teeth (incisors and cheek teeth in these species) continue to erupt throughout life, at up to 2 mm per week.

The ventral abdominal vein is located directly on the ventral midline and can be accidentally incised when a midline incision is used.

Treatments based on evidence that they will actually have a significant chance to improve the patients' condition without causing excessive detrimental effects are the gold standard in human medicine. In veterinary medicine we tend to look towards these standards to improve our practice and ultimately to provide the best possible care for our patients.

While the ferret is not considered to be a particularly exotic pet and in general its clinical medicine is very similar to feline clinical medicine, the interpretation of the ferret chemistry profile deserves special attention as there can be several pitfalls if ferret profiles are interpreted by comparing with cat or dog normal values.

While standard radiographic and ultrasound imaging techniques are common diagnostic tools in exotic animal medicine, the use of more advanced imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) currently appear to be underutilized for exotic patients.

The pathophysiology of adrenal gland disease in ferrets is significantly different from that in domesticated animals known as Cushings disease and therefore it should not be called Cushings disease in the ferret. Adrenal gland disease is considered the second most common disease in the ferret after insulioma.

Pancreatic islet beta cell tumors secrete high levels of insulin and cause hypoglycemia. Clinical signs include lethargy, weight loss, weakness, ptyalism, bruxism, seizures, and death. Treatment modalities include medical therapy, chemotherapy, surgery, and dietary changes.

Reptile surgery can be very complicated. Luckily in this day & age of Reptile Medicine, we are afforded several options for anesthetic as well as surgical techniques. This lecture will present a few in order to give an overview of some of the current options available to the practitioner.

As with any surgical procedure in any species; prior to cutting it is important to familiarize oneself with the relevant anatomical and physiological details of the species. A very detailed discussion of these two topics is beyond the scope of this presentation but the reader is strongly advised to familiarize oneself with these topics by the references listed below.

There are greater than 6500 species of extant reptiles with a wide variety of behaviors and structural morphologies designed to allow them to escape notice or fight off enemies, reproduce, obtain food and adapt to their environment. This lecture describes some commonly seen and some less commonly seen behaviors and morphological adaptations in reptiles.

Reptile surgery is performed under general anesthesia, observing sterile technique, with appropriate monitoring and supportive care. The true strength layer for reptiles is the skin. To prevent dysecdysis after a skin incision heals, an everting suture pattern is used.

Reptiles are very resilient and capable of surviving physiological changes e.g. severe hypoxemia, that would rapidly kill a mammal. Hypothermia should not be used as a method of restraint. It will induce immobility but will not provide analgesia. Hypothermia will also impair drug metabolism, digestion and immune function.

The procedure is generally very similar to a cat spay.

In general, information about an animal's origin and natural history is often the basis for recommendations concerning dietary management of these animals in captivity. In captivity, whether in an aquarium, screened cage, or (inappropriately) loose in the house – reptiles and amphibians have specific ranges for temperature, humidity, and ventilation which are essential for optimal health. Maintenance of an animal outside of its optimal range is a physiological stress that often results in poor intake, digestion/absorption, and utilization of food.

Ever wondered what it's like to work at a zoo? For one day, the dvm360 editors accompanied the veterinarian at the Kansas City Zoo and his team while they anesthetized a 5-year-old lioness named Zuri for a wellness exam.

Atlanta -- More than 200 people have now been infected with a strain of Salmonella Typhimurium associated with African dwarf frogs, reports the Centers for Disease Control and Prevention (CDC).

Erlanger, Ky -- Within days of the euthanization of a ferret at a Kentucky ferret shelter, 16 more fell sick from H1N1.

Columbus, Ohio -- Outgoing Ohio Gov. Ted Strickland, in one of his last official actions before leaving office Jan. 10, signed an executive order for a temporary ban on wild animal ownership.

Oklahoma City - The Oklahoma City Zoo is preparing to build a new $9 million veterinary hospital that will feature areas for public viewing.

Portland, Ore. -- The Oregon Department of Agriculture, as directed by state lawmakers in 2009, will stop issuing new exotic animal permits beginning in January 2011.
