Ornithobacterium rhinotracheale, or ORT, is a bacterium that causes respiratory disease in poultry. It can cause disease in birds of all ages and is potentially fatal.[2] O. rhinotracheale is found worldwide, and the bacterium may be spread between birds either horizontally or vertically. It is not a zoonosis.
Most commonly, respiratory signs are seen. These include nasal discharge, dyspnoea, sneezing and coughing. A drop in growth rates and abnormal egg production and joint problems may also be seen. There are reports of gastrointestinal and neurological symptoms in some cases.
Clinical signs are generally worse in meat producing birds.
Diagnosis
The disease caused by ORT is characterized by pneumonia, pleuritis and air sacculitis on postmortem examination. Diagnosis should be confirmed using laboratory tests such as bacterial culture, PCR, agar gel precipitation, ELISA, or serum agglutination.[2]
