SURVEY OF PREVALENCE OF ORNITHOBACTERIUM RHINOTRACHEALE IN BROILER FARMS AFFECTED WITH RESPIRATORY DISORDERS IN KARKAZI PROVINCE

Authors

Abstract

Respiratory diseases are considered as common disorders in broiler farms. Over the past decade a pleomorphic gram negative bacteria which isolated from broilers with respiratory diseases now calls ornithobacterium rhinotracheale . In this study, samples from trachea and lung collected from chicken with clinical respiratory signs in 173 broiler farms and then subjected on bacterial culture. The bacteria were identified using specific biochemical tests. The ornithobacterium rhinotracheale was isolated from 17 samples (9/8%) . in addition sensitivity of isolated bacteria against different antibiotic was examined with kerby- bauer method. As results most of the isolates were sensitive to doxycycline antibiotic. Therefore, biosecurity and vaccination in bieeders is recommended.
