Amphibian News
The world’s amphibians have undergone a pandemic caused by the chytrid pathogen Batrachochytrium dendrobatidis (Bd), and the devastation is worse than any previous disease. In 2013, a new chytrid pathogen, Batrachochytrium salamandrivorans (Bsal), was identified infecting and killing fire salamanders (Salamandra salamandra) in Europe. Martel et al (2014) proposed that Bsal was introduced into Europe on Asian salamanders transported to Europe in the international pet trade. A new study by Laking et al. (2017) supports that hypothesis by discovering Bsal in wild salamanders in Vietnam. They report low level Bsal pathogen endemism (<3% prevalence) in 8 species of salamanders. They also report two key discoveries: Bsal and Bd co-existence within populations, and Bsal can occur in warmer than expected water bodies.
