Summary statistics of entomologic risk for <i>Ixodes pacificus</i> infected with <i>Borrelia</i> spp. in recreational areas of the San Francisco Bay Area.

<p>¹Betsy Crowder Trail is comprised of coast live oak woodland.</p><p>²Anniversary Trail is comprised of coastal scrub and moderate grassland.</p><p>³Meadow Trail is comprised of coast live oak woodland and Douglas fir forest.</p><p>Data are presented on density of nymphal (DON) <i>I</i>. <i>pacificus</i> (i.e., number of nymphs/100m² (calculated by (number of ticks collected/meters covered by transects) x100); density of infected nymphs (DIN) for <i>Borrelia</i> spp. (calculated by <i>Borrelia</i> prevalence x DON); and for <i>B</i>. <i>miyamotoi</i>, <i>B</i>. <i>burgdorferi</i> ss, and for <i>B</i>. <i>burgdorferi</i> sl.</p
