We report successful helminthic transmission of Ehrlichia risticii, the cau
sative agent of Potomac horse fever, using trematode stages collected from
Juga yrekaensis snails. The ehrlichial agent was isolated from the blood of
experimentally infected horses by culture in murine monocytic cells and id
entified as E. risticii ultrastructurally and by characterization of three
different genes.
