Amphibian News
Genomic analysis reveals a complex evolutionary history. Genome sequences of 29 isolates of Batrachochytrium dendrobatidis (Bd) from around the world combined with data from 20 previously published isolates show that this potent amphibian pathogen has a complex history ( Rosenblum et al. 2013). It is neither new, nor very old (the root is estimated at 104,000 years old and the Panzootic lineage at 26,499 years), and thus it fits neither the novel pathogen nor the endemic hypothesis, but parts of both. The pool of genetic variation is deeper than previously thought. The need to identify specific mechanisms associated with shifts in virulence remains acute.
