Babesiosis in equines in Pakistan: a clinical report.

Equine babesiosis is a tick-borne haematological disease of equidae that can affect acutely, subacutely and chronically. The disease is manifested by intermittent fever, anaemia, icterus and haemoglobinuria. The authors describe the clinical, haematological and therapeutic aspects of babesiosis in equines at two units in Kotley and at two units in Jehlum of the Remount Veterinary and Farms Corps (RVFC). Animals on these units showed the signs of illness. On clinical examination, intermittent temperature, increased respiratory rate, anaemia, lacrimation, conjunctivitis and pale mucous membranes were observed. Haematological examination revealed a decrease in red blood cell count and haemoglobin concentration, accompanied by an increase in total white blood cell count. Cases of babesiosis in horses were successfully treated with imidocarb dipropionate at a dose rate of 4 mg/kg body weight, administered intramuscularly four times at 72 h intervals, together with supportive therapy.
