The Effect Of Chytridiomycosis And Bioaugmentation On The Metabolic Rate Of Redbacked Salamanders, Plethodon Cinereus, Jonathan Lenz

Life and Environmental Sciences Undergraduate Theses

The infectious disease chytridiomycosis caused by the fungal pathogen Batrachocytrium dendrobatidis, Bd, contributes to worldwide amphibian decline, but definitive pathogenesis of lethality for the disease is not well understood. Because amphibians respire through their skin (in addition to respiration using lungs), it is speculated that amphibians with chytridiomycosis may show a decrease in metabolic rate, but amphibians bioaugmented with probiotic bacteria may alleviate possible metabolic stress. A species of lungless salamander (Plethodon cinereus) was used in this study to analyze the cutaneous effects of Bd on metabolic rate in vivo. Net weight change, infection load (using a Taqman real time ...
