Description:Caption:
This photograph depicted a dorsal view of an adult female western blacklegged tick, Ixodes pacificus. This tick has been shown to transmit Borrelia burgdorferi, the agent of Lyme disease, and Anaplasma phagocytophilum, the agent of human granulocytic anaplasmosis (HGA), which was previously known as human granulocytic ehrlichiosis (HGE), in the western United States. As a female, the small scutum, or tough, chitinous dorsal abdominal plate, does not cover its entire abdomen, thereby allowing the abdomen to expand markedly when this tick ingests its blood meal. The four pairs of jointed legs, places ticks in the phylum, Arthropoda, and the class, Arachnida.
