Francisella philomiragia is a saprophytic gammaproteobacterium found only occasionally in immunocompromised individuals and is the nearest neighbor to the causative agent of tularemia and category A select agent Francisella tularensis. To shed insight into the key genetic differences and the evolution of these two distinct lineages, we sequenced the first complete genome of F. philomiragia strain ATCC 25017, which was isolated as a free-living microorganism from water in Bear River Refuge, Utah.
