ornithobacterium rhinotracheale (ort) is a respiratory pathogen which has been isolated throughout the world from numerous bird species. the present study was designed to isolate and characterize the ort from domestic turkeys, quails and pigeons. for this purpose, 250 samples from each bird species (turkey, quail and pigeon) with or without respiratory signs were tested by taking of tracheal...

Ornithobacterium rhinotracheale is a Gram-negative bacterium associated with respiratory diseases in many avian species, with worldwide distribution, and it causes significant economic loss to the poultry industry. In this study, the isolation and characterization of O. rhinotracheale small-colony variants (SCVs) are described for the first time. O. rhinotracheale isolates (n = 27) were recover...

The antimicrobial susceptibility of 19 Bordetella avium and 36 Ornithobacterium rhinotracheale strains was tested by the Kirby-Bauer disk diffusion method, and the minimal inhibitory concentrations (MIC) of amoxicillin, doxycycline and erythromycin were also determined. Most O. rhinotracheale strains were resistant to nalidixic acid, sulphamethoxazole-trimethoprim and gentamicin, and were susce...

Ornithohac/erium rhino/rachea/e (ORT) is a relatively rceently diseovered bacterium. which it is associated with respiratory diseases, Tracheal samplcs from carcasses of 100 roultry tlocks submitted to Razi Institute were examined for ORT isolation. Ali these tlocks were affected with respiratory disorders. Colonies of ORT were detected after 24h of incubation and identification of ORT isolates...
