Theileria

Theileriosis is a disease caused by a species of Theileria – a blood-borne parasite. It only affects cattle and is primarily transmitted by ticks. Theileria is a widespread disease with an increasing number of cases in the northern parts of the North Island. We have witnessed news cases appearing in the geographical area covered by Franklin Vets.

About

Tick

To become infected by Theileria, a cow must be bitten by a tick carrying the disease. It is not spread by direct animal to animal contact. Cattle can be infected with the Theileria parasite without necessarily showing any signs of clinical disease.
