About Ornithobacterium rhinotracheale (ORT)

Ornithobacterium rhinotracheale has been associated with respiratory disease, increased mortality, retarded growth and decreased egg production in avian species worldwide. Viral or bacterial infections by IBV, APV and NDV are able to trigger an ORT infection. An assessment of immune status, as well as serologic identification of ORT, requires a measurement of antibody to ORT in serum. Enzyme-linked immunosorbent assay (ELISA) systems have proven efficacious in the quantification of antibody levels to ORT, and facilitate the monitoring of immune status in large flocks. The IDEXX ORT Ab Test detects serological response to ORT serotypes A–M.
