Xenopus News.............New theories regarding origins and spread of Chytrid......

Close encounters with Japan's 'living fossil'
When the chytrid fungus was identified just over a decade ago, indications were that Japan would be an unlikely place to look for its origins. With the discovery of chytrid on museum specimens of the African clawed frog (Xenopus laevis), an out-of-Africa migration spurred by human transportation of amphibians once seemed the simple likelihood. But just last year, a team of researchers led by Koichi Goka from Japan's National Institute for Environmental Studies published research showing that certain strains of chytrid were present on Japanese giant salamanders, and only on Japanese giant salamanders, including museum specimens from a century or so back; and that the relationship seemed benign.
