A new paper by Anna Savage and Kelly Zamudio suggests that amphibian populations may be evolving tolerance to Bd. This result is based on the analysis of MHC loci.
The authors write "Our findings indicate that selective pressure for Bd survival drives rapid immunogenetic adaptation in some natural populations, despite differences in environment and demography. Our field-based analysis of immunogenetic variation confirms that natural amphibian populations have the evolutionary potential to adapt to chytridiomycosis."
