“…If the possibility of a positive ADH-test is included (code 0±3±2±0±0±0±4 or 0±1±2±0±0±0±4) a 100% identi® cation score with the API-20NE strip was found, in accordance with those positive in the AGP test (van Empel et al, 1996;. Another commercial identi® cation system, the RapID NF Plus system (Innovative Diagnostics, USA), gave high identi® cation scores (Biocodes 4±7±2±2±6±4, 4±7±6±2±6±4, 6±7±6±2± 6±4 or 6±7±2±2±6±4) when investigating 110 O. rhinotracheale strains (Post et al, 1997). The API-ZYM system is used also for identi® cation purposes, since the enzymatic properties of O. rhinotracheale were found to be fairly constant (Hafez, 1998a;Ryll & Hinz, 1997).…”

Ornithobacterium rhinotracheale is a relatively recently discovered bacterium of the rRNA superfamily V. It is of worldwide distribution in commercial poultry, in which it is associated with respiratory diseases, and it is also found in wild birds. Airsacculitis and pneumonia are the most common features of infection with O. rhinotracheale. These signs can be induced by aerosol in intra-tracheal or intra-thoracic administration of the organism, and can be aggravated by other factors, such as respiratory viruses, bacteria or climatic conditions. Osteitis, meningitis and joint-infections, which can be induced by intravenous application, have been associated with O. rhinotracheale, but it remains uncertain whether the organism should be regarded as a primary pathogen. The infection can be transmitted horizontally by aerosol, as well as vertically through eggs, which probably accounts for its rapid and worldwide spread.Although O. rhinotracheale is dif® cult to identify, some commercial identi® cation systems have been found to be suitable, although the media used in such systems will not always support its growth. A PCR assay was also found to be suitable for identi® cation purposes. Twelve serotypes can be distinguished within the species O. rhinotracheale, of which serotype A is the most prevalent. Genetic investigation has revealed that more species or subspecies probably exist within the genus Ornithobacterium.
