Chromosome and Large Linear Plasmid Sequences of a Borrelia miyamotoi Strain Isolated from Ixodes pacificus Ticks from California.

Borrelia miyamotoi, a relapsing fever group spirochete, is an emerging tick-borne pathogen. It has been identified in ixodid ticks across the Northern Hemisphere, including the West Coast of the United States. We describe the chromosome and large linear plasmid sequence of a B. miyamotoi isolate cultured from a California field-collected Ixodes pacificus tick.
