Abstract
The fungus Batrachochytrium dendrobatidis has been linked to the decline of amphibians worldwide. Research has been devoted to examining the range of B. dendrobatidis and various physiological aspects of the fungus; however, little is known about how it causes mortality in individuals. Subsequently, we investigated the potential mechanisms of mortality by examining the pathogen's effect on metabolic rate and osmotic balance. In addition, we attempted to develop a field treatment for the pathogen using Itraconazol. Metabolic rates, mass, pathogen symptoms and osmotic concentrations were measured in Rana pipiens and Hyla rigilla. Results suggest symptoms are variable and individuals survive for over 100 days with infection. In addition, mail ordered Rana pipiens may be a source of the spread of Bd and we urge containment of potentially infected individuals. Lastly, Itraconazol is not effective at clear infection in Rana pipiens.
