  • Beschreibung: <jats:title>Abstract</jats:title><jats:p>Amphibian chytridiomycosis, an emerging infectious disease caused by the fungus <jats:italic>Batrachochytrium dendrobatidis</jats:italic> (<jats:italic>Bd</jats:italic>), has been a significant driver of amphibian declines. While globally widespread, <jats:italic>Bd</jats:italic> had not yet been reported from within Madagascar. We document surveys conducted across the country between 2005 and 2014, showing <jats:italic>Bd</jats:italic>'s first record in 2010. Subsequently, <jats:italic>Bd</jats:italic> was detected in multiple areas, with prevalence reaching up to 100%. Detection of <jats:italic>Bd</jats:italic> appears to be associated with mid to high elevation sites and to have a seasonal pattern, with greater detectability during the dry season. Lineage-based PCR was performed on a subset of samples. While some did not amplify with any lineage probe, when a positive signal was observed, samples were most similar to the Global Panzootic Lineage (<jats:italic>Bd</jats:italic>GPL). These results may suggest that <jats:italic>Bd</jats:italic> arrived recently, but do not exclude the existence of a previously undetected endemic <jats:italic>Bd</jats:italic> genotype. Representatives of all native anuran families have tested <jats:italic>Bd</jats:italic>-positive and exposure trials confirm infection by <jats:italic>Bd</jats:italic> is possible. <jats:italic>Bd</jats:italic>'s presence could pose significant threats to Madagascar's unique “megadiverse” amphibians.</jats:p>
