Abstract

A brief summary of the currently accepted aetiology and pathogenesis of footrot and interdigital dermatitis in sheep in Great Britain is presented together with a description of the transmission dynamics of Dichelobacter nodosus. Approaches that may be successful for control or elimination of the disease are proposed and areas of uncertainty in current knowledge highlighted. Research and practice in Great Britain is compared with that from other countries and the proposal made that the environment and/or carrier (non-diseased) sheep may assist persistence of footrot.
