Episode #8 – From Bees to Clones

In this month’s Podcast, Mariely Medina and Jonathan Sogin take us from B to C; or honey bees to E. coli clones. They discuss Glyphosate and its impact on honey bees’ microbiome, and how whole-genome sequencing can be used to determine the phylogeny of pathogenic outbreak strains.
