The relapsing fever spirochete Borrelia miyamotoi is cultivable in a modified Kelly-Pettenkofer medium, and is resistant to human complement

Commentary: I’m speaking on 9/16 at the CALRB symposium on tick-borne disorders in Hartford, Connecticut, on the relapsing fever spirochete Borrelia miyamotoi. This organism is now prevalent in ticks, and in certain parts of the US, is being transmitted as often as the Lyme disease spirochete, Borrelia burgdorferi. The relapsing fever spirochete B. miyamotoi has recently been found to be cultivable in a special culture medium (MKP-F) and resistant to complement killing, increasing its pathogenesis. B. miyamotoi joins the list of other common tick-borne co-infections now infecting humans, and may be playing a role in contributing to seronegative persistent disease among certain chronically ill patients.
