[email protected] Abstract.—Amphibian fungal diseases have been implicated in a number of extinctions and declines worldwide. To establish the presence/absence of the amphibian pathogen Batrachochytrium dendrobatidis (Bd) on conservation lands in northern and south-central New Brunswick, Canada, we sampled eight species of anurans and six species of caudate amphibians (n = 390). Six species, including Rana catesbieana (American Bullfrog), R. clamitans (Green Frog), R. sylvatica (Wood Frog), Desmognathus fuscus (Northern Dusky Salamander), Plethodon cinereus (Eastern Red-backed Salamander) and Notopthalmus viridescens (Eastern Newt) tested positive for Bd. Prevalence for Bd in New Brunswick amphibians was low overall (4.6%) relative to those reported from surrounding states and provinces; however, two plethodontid salamanders, D. fuscus and P. cinereus, had the highest Bd prevalence among any of the amphibians sampled (9.1% and 12.9% respectively).
