Amphibian Health In A Public Aquarium  Marisa A. Giardina, Brent R. Whitaker   National Aquarium in Baltimore, Pier 3/501 E. Pratt Street, Baltimore, MD     Although leopard frogs and axolotls have been studied in the laboratory for more than a century, it is only within the past 20 years that amphibians have gained significant popularity in zoos and aquariums. This has led to the need for veterinarians who are knowledgeable about amphibian husbandry, health assessment and medical care. As with fish, proper husbandry, which includes housing, environmental parameters, social environment and nutrition, is essential to maintaining amphibian health. When an amphibian presents with signs of disease, these factors must be considered as part of a complete health assessment, along with evaluating the complete history and the physical exam with appropriate sample collection. Identification of problems with husbandry or pathogens, including bacterial, fungal, parasitic and viral agents, helps the veterinarian to form differential diagnoses and develop a therapeutic plan for successful medical care.
