Abstract

The first identification of Ornithobacterium rhinotracheale (ORT) in Egypt was undertaken from an outbreak of respiratory disease in 5000 broilers ageing 38 days with 7.12% mortality during 20 days. The recorded clinicopathological picture was similar to that reported from broilers in Europe, USA and South Africa as being associated with ORT. ORT concurrently isolated with E.coli from lungs and air sacs of examined cases.
