Batrachochytrium salamandrivorans (Bsal) not detected in an intensive survey of wild North American amphibians

摘要: The salamander chytrid fungus (Batrachochytrium salamandrivorans [Bsal]) is causing massive mortality of salamanders in Europe. potential for spread via international trade into North America and the high diversity has catalyzed concern about Bsal U.S. Surveillance programs invading pathogens must initially meet challenges that include low rates occurrence on landscape, prevalence at a site, imperfect detection diagnostic tests. We implemented large-scale survey to determine if was present designed target taxa localities where determined highest risk be based species susceptibility geography. Our analysis included Bayesian model estimate probability given our prior knowledge pathogen. failed detect any 11,189 samples from 594 sites 223 counties within 35 states one site Mexico. modeling indicates highly unlikely occur wild amphibians suggests best proactive response continue mitigation efforts against introduction establishment disease develop plans reduce impacts should establish.
