Two papers out this week on the population dynamics and epidemiology of the chytrid pathogen of amphibians, Batrachochytrium dendrobatidis (Bd). This is work from the Vredenburg and Briggs labs that includes several decade-long studies of frog declines and the prevalence of Bd.

An article in PLoS Pathogens by Morris et al describe a hypothesis about the evolution and origins of plant pathogens applying the parallel theories to the emergence of medically relevant pathogens. The authors highlight the importance of understanding the evolution of organisms in the context of emerging pathogens like Puccinia Ug99 for our ability to design strategies to protect human health and food supplies. Both bacterial and fungal pathogens of plants are discussed but I (perhaps unsurprisingly) focus on the fungi here. Continue reading Origins and evolution of pathogens

As part of the dermatophyte efforts and emerging infectious diseases the Fungal Genome Initiative at the Broad Institute will be sequencing the genome of Geomyces destructans. G. destructans is linked to the white-nose syndrome in Bats.

A nice series of comparative genomics articles have been published in the last few weeks. The pace of genome sequencing has accelerated to the point that we have lots of sequencing projects coming from individual labs and small consortia not necessarily from genome centers. We are seeing a preview of what next (2nd) generation sequencing [...]

A Brevia piece in Science today describes efforts to describe the causal agent in white-nose syndrome (WNS) in bats which appears to be contributing to bat decline. According to the authors, previous work had described an uncharacterized fungus associated with bats that showed signs of being sick with WNS.
