The Effects Of Chytridiomycosis On Myocardial Oxygenation In Columbian Spotted Frogs (Rana Luteiventris), Kaitlyn Holyfield

Life and Environmental Sciences Undergraduate Theses

Chytridiomycosis is an infection in amphibians caused by the fungus Batrachochytrium dendrobatidis that has been linked to world-wide amphibian decline. However, there is currently no clear explanation of how this infection is killing amphibians. I hypothesize that the fungus is preventing effective cutaneous gas exchange, causing hypoxia in the heart which could lead to myocardial ischemia. The objectives of this study are to find an organism that is susceptible to Chytridiomycosis which can be used as a model for detecting myocardial ischemia in frogs and to establish a protocol for ischemia detection. Rana luteiventris (Columbian Spotted Frogs) were collected and ...
