Key Points

Bovine babesiosis (“red water disease”) is a tick-borne protozoal disease caused by Babesia spp.
Infection results in acute haemolytic anaemia, leading to pyrexia, weakness, tachycardia and haemoglobinuria (“red water”)
- Calves and youngstock are typically mildly affected whereas adults can develop serious disease
Diagnosis is typically presumptive, based on the clinical presentation, risk of tick exposure and findings on a blood smear
Antiprotozoals are used alongside supportive care for treatment
Prevention relies on good tick control to minimise exposure and intentionally exposing youngstock in endemic areas to encourage development of immunity

Differential Diagnoses

Leptospirosis
Bacillary haemoglobinuria
