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 polymerase chain reaction methods.
