Some non-native frogs are harboring an unwelcome hitchhiker in their home in the UK, according to this article from BBC News. The American bullfrogs (Rana catesbeiana) were found to be carrying a chytrid fungus (Batrachochytrium dendrobatidis), something that doesn't affect them but could be deadly to native British frog species. This is the first time the fungus has been found on animals living in the wild in the UK. Back in June the ISW reported that the same fungus was discovered in Tasmania.
