TLDR
The growth and biological characteristics of isolates of Ornithobacterium rhinotracheale from commercial broiler chickens in the mid-Atlantic region of the U.S.A. appear to be identical to those previously reported in the literature, and the diagnostic cases included in this report were often associated with known respiratory pathogens.Abstract:
The growth and biological characteristics of isolates of Ornithobacterium rhinotracheale (ORT) from commercial broiler chickens in the mid-Atlantic region of the USA appear to be identical to those previously reported in the literature The clinical disease and lesions are also similar to those reported from other poultry growing regions including South Africa and Europe The diagnostic cases included in this report were often associated with known respiratory pathogens, namely, lentogenic Newcastle disease virus, and infectious bronchitis virus, and Escherichia coli bacteria The role of ORT in the disease cases presented in this report is unclearread more

TL;DR: Although O. rhinotracheale is difficult to identify, some commercial identification systems have been found to be suitable, although the media used in such systems will not always support its growth.

Infectious Coryza: Overview of the Disease and New Diagnostic Options
TL;DR: A new DNA-based diagnostic technique, involving PCR, has been recently described and will greatly assist in the diagnosis of infectious coryza, resulting in severe disease and significant economic losses.

Studies on the bacterial etiology of airsacculitis of broilers in northern and middle Jordan with special reference to Escherichia coli, Ornithobacterium rhinotracheale, and Bordetella avium.
TL;DR: In vitro susceptibility testing revealed that E. coli isolates were sensitive to gentamicin and colistin, O. rhinotracheale to tetracyline, and B. avium to most of the nine antibiotics examined.
Journal ArticleDOI
Immunohistochemical and serological investigation of experimental Ornithobacterium rhinotracheale infection in chickens.
TL;DR: Infection with O. rhinotracheale appears to be restricted to the respiratory tract, with lesions only evident in birds previously infected with NDV, even though a strong serological response can be established in the absence of prior viral infection.

TL;DR: An unidentified, pleomorphic, gram-negative rod (PGNR) bacterium has been isolated from domestic fowl with respiratory disease, however all 14 isolates were similar.
