Killer fungus invades Europe

Using data from field surveillance, a new study showed that the killer fungus now occurs in many new places in the Netherlands and Belgium. In addition, it was found for the first time in the wild in Germany. The study also shows that the fungus infects additional species in the wild. The fungus was detected at 14 of the 55 sampled sites. The infected amphibians were fire salamanders, alpine newts, and smooth newts. 'Our results demonstrate that the range of Bsal distribution may be up to about 10,000 km² across Germany, Belgium and the Netherlands" says Annemarieke Spitzen-van der Sluijs who led the study. She adds "Our study provides evidence that Bsal among wild amphibians in Europe is more wildely distributed and affects a wider host range than previously known, which can either indicate recent spread of the fungus or point to historically infected sites that hitherto remained undetected. The presence of Bsal in wild populations can easily remain unnoticed because the lesions develop only near the final stage of the disease."

The international research team says that further surveillance of the chytrid fungus is very important. Spitzen-van der Sluijs asks for help from the public. "Please report sick or dead salamanders and newts so we can further fill the map of the distribution of the fungus in Europe."
