Caused by E. phagocytophila which has now been renames as Anaplasma phagocytophilum
Affects ruminants in Europe
The tick Ixodes ricinis is the main vector
Animals remain carriers for up to 2 years, but are immune to reinfection

Diagnosis
- Intracytoplasmic morulae in neutrophils of Giemsa-stained blood smears during acute phase
- Seroconversion detected by immunofluorescence

- Oxtetracycline
- Tick control
- Prophylactic tetracyclines for lambs during first few weeks of life
