Borrelia prevalence in various CA ticks

Excerpt:
This finding and an antecedent report of a B. burgdorferi-like
spirochete from the same tick species demonstrate that O. coriaceus
sometimes acquires and transstadially passes Lyme disease group
spirochetes. I. pacificus nymphs inhabiting a woodland nidus of B.
burgdorferi and A. phagocytophilum had a 5-fold higher prevalence of
borreliae than adult ticks from the same generational cohort. In
contrast to the results of preceding studies carried out at the same
site, none of the nymphal or adult ticks was PCR-positive for A.
phagocytophilum. This suggests that the distribution of this rickettsia
is highly focal or variable from year-to-year within this particular
woodland.
