Pseudacris triseriata (western chorus frog) and Rana sylvatica (wood frog) – Chytridiomycosis

Abstract/Summary

PSEUDACRIS TRISERIATA (Western Chorus Frog) and RANA SYLVATICA (Wood frog). CHYTRIDIOMYCOSIS. Chytrid fungus (Batrachochytrium dendrobatidis) is a known pathogen of anuran amphibians, and has been correlated with amphibian die-offs worldwide (Daszak et. al. 1999. Emerging Infectious Diseases 5: 735-748). In Colorado, B. dendrobatidis has infected Boreal toads (Bufo boreas)and has been identified on museum specimens of northern leopard frogs (Rana pipiens) (Carey et. al. 1999. Developmental and Comparative Immunology 23: 459-472). We report the first verified case of chytrid fungus in chorus frogs (Pseudacris triseriata) and wood frogs (Rana sylvatica) in the United States.
