Nonreproductive surgery in reptiles.

As reptiles have gained popularity as pets, veterinarians are more frequently called on to perform surgical procedures on these pets. Veterinarians must have a basic understanding of the anatomic and physiologic differences between reptilian and mammalian companion animals. This article reviews some basic points about reptilian anatomy and physiology that are important to consider when performing surgery on reptilian patients. This article covers approaches to the coelomic cavity in the different groups of reptiles and some basic concepts regarding surgery on different, nonreproductive systems in these reptiles.     

Wound management in reptiles.

Our understanding into the healing response of reptile wounds is in its infancy. To date, many of the methods we have used have been adopted from human, mammalian, or avian species, with varying success. Future research should focus on the development of methods to improve our management of contaminated wounds, minimize the negative inflammatory responses occurring in a wound, and shorten wound-healing time.     

Renal pathology in reptiles.

The class of Reptilia varies widely. Both the gross morphology and microscopic anatomy of the kidneys are specific for each species.In each species of reptile, the physiology of the renal system has adapted to the specific conditions of life, including, among other factors, the type of food, environmental temperature, and the availability of water. The pathology of the kidneys in reptiles has been poorly studied, but in recent years a number of investigators have specifically studied reptilian renal pathology.     

Metaldehyde: Pet Poisonings

Sir, — This year proprietors of metaldehyde-based products advised the Board that a material available from the United Kingdom, known as Alamask, was an effective animal repellent.     

Nutrition of captive reptiles.

In reptile practice, most nutritional problems arise from improper husbandry, including poor feeding management and provision of imbalanced diets. Each reptile species has its own requirements for temperature and humidity, space and social interaction, lighting, and habitat components. Failure, to provide these requirements often results in failure to thrive and secondary nutritional disorders. Common dietary problems include deficiencies of energy, calcium, vitamin D3, vitamin A, and fiber.     

Clinical evaluation of reptiles.

A detailed history and physical examination usually provides the veterinarian with a list of possible differential diagnoses and indicates which further investigations may be necessary to make a definitive diagnosis. Radiography, ultrasonography, endoscopy, hematology, blood biochemistry, and microbiological and parasitologic investigations are all proven techniques that are used extensively in reptile medicine. A logical case workup enables the clinician to make a previously elusive reptile diagnosis and offers this interesting group of animals veterinary services comparable with that already expected for more domesticated pets.     

Salmonellae and salmonellosis in captive reptiles.

In a survey of 150 pet reptiles submitted for necropsy, 51% of snakes, 48% of lizards and 7% of turtles were infected with Salmonella. About one third of the positive animals had died due to various manifestations of salmonellosis. Thirty-one Salmonella serotypes were identified including three isolates new to Canada. The public health implications are discussed in view of the restricted popularity of reptiles and their possible infection from domestic agricultural products.     

Renal diseases of reptiles.

Renal disease is one of the most common problems in reptilian medicine. Herbivorous species seem to be more susceptible than carnivores. The causation may be multifactorial, and the signs are often nonspecific. Prevention is preferred to treatment, and a comprehensive health program, which includes quarantine, routine health screens during annual examinations, and necropsy examinations of all animals that die, is desirable.     

Emergency care of reptiles.

Common reptile emergencies are reviewed in this article and the fundamentals of emergency care are provided. Important points include obtaining a complete history and husbandry review, physical examination, diagnostic tests, fluid support, anesthetics, and antibiotics.     

Fungal diseases of reptiles.

Fungal infections affecting the integumentary system, the upper and lower respiratory system and the gastro-intestinal tract have been reported in many species of captive reptiles. Systemic mycoses are diagnosed rarely in reptiles, and in most cases, they are a postmortem finding. Commonly, immunocompromised reptiles, kept in suboptimal environmental conditions are affected. In many cases, mixed bacterial and fungal infections of opportunistic organisms may be present. A diagnosis of a primary fungal infection is based on proper selection and collection of diagnostic specimens such as biopsies of infected tissues. Treatment of fungal infections in reptiles includes administration of effective antifungal agents and correction of inappropriate environmental conditions such as poor hygiene, too high or too low temperature and humidity, inadequate diet, and stress from overcrowding. Few studies have investigated effective dosages and dosage intervals of antifungal agents in reptiles.     

Common procedures in reptiles and amphibians.

Reptiles and amphibians continue to be popular as pets in the United States and throughout the world. It therefore behooves veterinarians interested in caring for these exotic species to continually gather knowledge concerning both their proper husbandry and the conditions that require medical and/or surgical intervention.This article covers husbandry, physical examination, and clinical and diagnostic techniques in an effort to present guidelines for the evaluation of the reptile or amphibian patient. Gathering clinical data will aid veterinarians in arriving at the proper diagnosis,increasing the chances of success with treatment protocols, and educating the clients in proper nutrition and husbandry for their pets.     

Viruses in reptiles

ABSTRACT: The etiology of reptilian viral diseases can be attributed to a wide range of viruses occurring across different genera and families. Thirty to forty years ago, studies of viruses in reptiles focused mainly on the zoonotic potential of arboviruses in reptiles and much effort went into surveys and challenge trials of a range of reptiles with eastern and western equine encephalitis as well as Japanese encephalitis viruses. In the past decade, outbreaks of infection with West Nile virus in human populations and in farmed alligators in the USA has seen the research emphasis placed on the issue of reptiles, particularly crocodiles and alligators, being susceptible to, and reservoirs for, this serious zoonotic disease. Although there are many recognised reptilian viruses, the evidence for those being primary pathogens is relatively limited. Transmission studies establishing pathogenicity and cofactors are likewise scarce, possibly due to the relatively low commercial importance of reptiles, difficulties with the availability of animals and permits for statistically sound experiments, difficulties with housing of reptiles in an experimental setting or the inability to propagate some viruses in cell culture to sufficient titres for transmission studies. Viruses as causes of direct loss of threatened species, such as the chelonid fibropapilloma associated herpesvirus and ranaviruses in farmed and wild tortoises and turtles, have re-focused attention back to the characterisation of the viruses as well as diagnosis and pathogenesis in the host itself.1.

Common procedures with venomous reptiles.

Venomous reptiles should be handled in a safe and consistent man-ner, even after death. Owners and staff should be warned not to handle the venomous reptile, and one should have emergency protocols in place before the properly bagged and encased reptile is presented. It is important to know what one is treating as well as one's limitations. After being carefully removed from the bag, the venomous reptile may be transferred to a handling container, tubed, or squeezed with the appropriate equipment. The author usually induces injectable or gas anesthesia at this point. Veterinarians who are inexperienced with venomous reptiles should learn how to handle them through a reputable seminar or class before electing to see them in their practice.     

Cloacoscopy in reptiles

Endoscopy of the reptile cloaca is a noninvasive method for the diagnosis of disorders of the cloaca and the structures which empty into it. The technique may also be helpful in sex determination and for local administration of drugs.

Parasites in pet reptiles

Exotic reptiles originating from the wild can be carriers of many different pathogens and some of them can infect humans. Reptiles imported into Slovenia from 2000 to 2005, specimens of native species taken from the wild and captive bred species were investigated. A total of 949 reptiles (55 snakes, 331 lizards and 563 turtles), belonging to 68 different species, were examined for the presence of endoparasites and ectoparasites. Twelve different groups (Nematoda (5), Trematoda (1), Acanthocephala (1), Pentastomida (1) and Protozoa (4)) of endoparasites were determined in 26 (47.3%) of 55 examined snakes. In snakes two different species of ectoparasites were also found. Among the tested lizards eighteen different groups (Nematoda (8), Cestoda (1), Trematoda (1), Acanthocephala (1), Pentastomida (1) and Protozoa (6)) of endoparasites in 252 (76.1%) of 331 examined animals were found. One Trombiculid ectoparasite was determined. In 563 of examined turtles eight different groups (Nematoda (4), Cestoda (1), Trematoda (1) and Protozoa (2)) of endoparasites were determined in 498 (88.5%) animals. In examined turtles three different species of ectoparasites were seen. The established prevalence of various parasites in reptiles used as pet animals indicates the need for examination on specific pathogens prior to introduction to owners.
