"The most important agricultural insect, the honey bee, houses multiple bacterial symbionts that provide distinct benefits under environmental stress. Our lab has been at the forefront of identification and characterization of the honey bee microbiome, using a polyphasic approach combining in vivo, in vitro, microbiological, and 'omics assays. I will present our most recent results on the microbe Bobella apis - who it is, what it's doing in association with the bee, and its evolution in symbiosis."
