Diagnosis of ehrlichiosis from the presence of inclusion bodies or morulae of E can is

Peripheral blood smears (stained with May‐Griinwald‐Giemsa) taken from 250 dogs showing clinical signs suggestive of ehrlichiosis were examined for the presence of inclusion bodies or morulae of Ehrlichia canis. Inclusion bodies were seen in 220 (88 per cent) cases, of which only 9 (4 per cent) cases exhibited morulae. Thus inclusions other than morulae may play an important role in the diagnosis of canine ehrlichiosis in enzootic areas.
