Cattle babesiosis

Theileriosis is a tick-borne disease of cattle and sheep. The parasites are intracorpuscular but, unlike in babesiosis, the blood cells are not destroyed. The major symptoms are those of toxaemia and once the parasite has invaded the blood, there is high, rapid mortality.

This does present farmers with some particular difficulties. It means that once treated, cattle can then not be sold on for human consumption for over seven months. Should an animal sustain an injury that requires humane slaughter, it cannot enter the human food chain until the withdrawal period had elapsed. This means that treating animals for the prevention of babesiosis cannot be undertaken lightly as there are practical and economic considerations to be considered.
