Tick Surveillance Update for Water Year 2018-2019

Laboratory staff continued collecting Ixodes pacificus ticks in the nymph life stage and adult Dermacentor ticks during the month of May. Collections in May occurred at Thornewood Open Space Preserve near Woodside, Wunderlich County Park in Woodside, Water Dog Lake Park in Belmont, Big Canyon Park and Eaton Park in San Carlos, Edgewood Park in Redwood City, Costanoa campground near Año Nuevo, and Laurelwood Park in San Mateo. Ixodes pacificus nymphs are active in the spring, and more difficult to collect in abundant numbers than adult ticks because they are typically on fallen logs or in leaf litter, whereas adult ticks are easily found on the edges of vegetation along trails. Ticks of the genus Ixodes will be tested for the Lyme disease causing bacteria Borrelia burgdorferi and other disease causing bacteria Borrelia miyamotoi and Anaplasma phagocytophilum. Ticks of the genus Dermacentor will be tested for tularemia.
