new update about Lyme Borrelia (Borrelia burgdorferi sensu stricto and Bbsl) and one species of Relapsing Fever Group Borrelia (Borrelia miyamotoi) found in ticks from a region of California.

Here's a new update about Lyme Borrelia (Borrelia burgdorferi sensu stricto and Bbsl) and one species of Relapsing Fever Group Borrelia (Borrelia miyamotoi) found in ticks from a region of California.

"In adult I. pacificus ticks in the San Francisco Bay area, B. miyamotoi is as abundant as its congener B. burgdorferi. Human disease caused by B. miyamotoi infection has not been reported in California, and transmission efficiency of B. miyamotoi by I. pacificus ticks is unknown. However, it is possible that B. miyamotoi infections in ticks and humans have not been accurately diagnosed. We advocate for increased scrutiny of the eco-epidemiology of B. miyamotoi in human, tick, and possible vertebrate host populations in northwestern California."
