As an adjunct in the diagnosis of ehrlichiosis and/or in seroepidemiological surveys of the prevalence of the infection in certain populations
Ehrlichiosis is sometimes diagnosed by observing the organisms in infected WBCs on Giemsa-stained thin blood films of smeared peripheral blood (morulae). Serology may be useful if the morulae are not seen or if the infection has cleared naturally or following treatment.
Serology may also be useful in the follow-up of documented cases of ehrlichiosis or when coinfection with other tick- transmitted organisms is suspected. In selected cases, documentation of infection may be attempted by PCR methods.
