Canine monocytic ehrlichiosis

  • Generalised disease of dogs in tropical and subtropical regions
  • Caused by Ehrlichia canis
  • The brown tick, Rhipicephalus sanguineus, is the main vector
  • Dogs may carry the organism for 2 years after resolution of clinical signs
  • Clinical signs
    • Incubation period of 3 weeks
    • Acute, subclinical or chronic phases
    • Acute phase: fever, thrombocytopenia, leukopenia and anaemia
    • Subclinical phase: low blood cell numbers but minimal clinical signs; can progress to a severe disease, tropical canine pancytopenia
    • Chronic phase: bone marrow depression, haemorrhages, neurological disease, peripheral oedema, emaciation and hypotensive shock
  • Diagnosis
    • E. canis morulae present in mononuclear cells in Giemsa-stained blood smears
    • Rising antibody titre detected by indirect immunofluorescence
    • Culture in canine macrophages
  • Treatment and control
    • Doxycycline for 10 days
    • Fluid therapy or blood transfusion
    • Prophylactic tetracyclines
