Coccidiosis in cattle

All calves are subjected to infection with coccidia, yet most do not develop clinical disease. Where disease does occur, it can be challenging to diagnose accurately and in an era where in-feed medication or prophylactic/metaphylactic use of medicines could be banned or severely restricted this condition could become very challenging on some units. In this article we briefly explore the current evidence supporting the epidemiology, and pathogenesis of this disease, and also the challenges for treatment and control.
