ABSTRACT: Batrachochytrium dendrobatidis has been investigated worldwide because of its importance in population declines in multiple species of amphibians; however, little is known regarding the disease status of all native amphibian species in China. The present study is the first survey of chytridiomycosis in free-ranging amphibian populations in China, and it examined the possible presence of B. dendrobatidis in Rana dybowskii in northeastern China (Heilongjiang Province). R. dybowskii is mainly distributed in the northeast part of China and is intensively hunted for human consumption, making populations vulnerable to extirpation in the event of additional stresses from disease epidemics. The survey was performed in early spring of 2008, using a PCR assay, histological examination of skin samples, and zoospore culture. In total, 191 frogs were examined; thus, a 95% confidence limit for prevalence of 1.57% was selected. Our results demonstrate that R. dybowskii is currently free from chytridiomycosis in Heilongjiang, even though the natural conditions of the sampling sites are suitable for the occurrence of B. dendrobatidis. Central and local governments should implement strict management measures to prevent the escape of non-native commercial amphibian species into this area, which might endanger local populations of native species.
