The purpose of this research was to contribute to the preservation of ecosystems and biodiversity in Japan. Therefore, this work involved the risk profiling of pathogens, along with assessment of epidemics in exotic and wild animals, to establish the measure of threat. Batrachochytrium dendrobatidis, Bd was widely distributed with a high prevalence in Japan. Native species have more varied haplotypes. The noninvasive Bd detection procedure and the disinfecting method were established. The epidemic pattern of ranavirus in captive and wild amphibian populations in Japan was clarified. The high pathogenicity of two isolates to native species was demonstrated. Moreover, it was shown that the distribution of the ranavirus has extended, and that its prevalence ratio is sharply rising. The results of these research activities were published in scientific journals. This study produced useful information facilitating the construction and implementation of a practical epidemic prevention system.
