- 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
- Clinical signs
- Incubation period of 2 weeks; recovery in 2 weeks
- Fever, anorexia, reduced growth rates in young animals
- Reduced milk production, abortion, still birth
- Leukopenia and thrombocytopenia
- Causes immunosuppression in young lambs causing susceptibility to tick pyaemia and louping ill
- Diagnosis
- Intracytoplasmic morulae in neutrophils of Giemsa-stained blood smears during acute phase
- Seroconversion detected by immunofluorescence
- Treatment and control
- Oxtetracycline
- Tick control
- Prophylactic tetracyclines for lambs during first few weeks of life
