Ixodes woodi

The distribution of I. woodi in the USA includes AL, AZ, CA, CO, ID, IN, KS, NC, NM, NV, OK, OR, SC, TX, UT, and WY; in Mexico, the states of Coahuila, Morelos, and Tamaulipas.


Hosts are primarily woodrats, but also other rodents, birds, shrews, and incidentally, humans.

Vector Status

DNA of the agent of human granulocytic anaplasmosis was isolated in Ixodes woodi ticks in California; although no vector status was demonstrated, it seems likely that this tick is involved in a zoonotic cycle of the agent among woodrats.
