The new genetic analysis of chytrid fungus is published today in the Proceedings of the National Academy of Sciences.
Professor Hamish McCallum, a chytrid expert from Griffith University says the fungus is threatening more species than any other vertebrate pathogen.
He welcomes the new research, but says it raises more questions than it answers.
“It is an interesting piece of work but it literally opens up a can of worms,” says McCallum.
He says the research shows that the pandemic strain has much greater diversity than previously thought.
