title: Two cases of Neorickettsia (Ehrlichia) risticii infection in horses from Nova Scotia.
abstract: Two horses from Nova Scotia were diagnosed with Potomac horse fever (PHF). Polymerase chain reaction analysis was performed on formalin-fixed colon tissue or whole blood to show the presence of Neorickettsia risticii DNA, the causative agent of PHF. These are the first reported cases of PHF in the Maritime Provinces.
