Aetiology of Ovine Footrot in the Portuguese Region of Alto Alentejo

Abstract

In this work, we found it appropriate to carry out a study directed towards isolating and identifying the entailed microorganisms which trigger off footrot in sheep, placing special emphasis on the serotipification of the different Dichelobacter nodosus species. With this goal in mind four flocks from the Portuguese region of 'Alto Alentejo' were selected, all of them had one common feature: their main health problem was ovine footrot. We also set out to determine the elastolitic capacity of isolated strict-anaerobic bacteria, in order to be able to clarify the direct involvement of these microorganisms in the outbreak of this infectious process.
