A skin-eating fungus that infiltrated Europe through the global wildlife trade is threatening to inflict massive losses on the continent's native salamanders including extinction of whole species and could do the same in North America, scientists say.

An international research team said Thursday the fungus, first detected in Europe last year, has killed salamanders in the Netherlands and Belgium and is expected soon to reach other European nations. They said it is closely related to another fungus that already has wiped out some amphibian species.

The scientists have found no sign of the fungus in North American amphibians but worry that it is only a matter of time before it surfaces via a pet trade that has funneled millions of Chinese fire-bellied newts to the United States.
