Technical Abstract: Atrophic Rhinitis (AR) is a complex upper respiratory tract disease of pigs that results in loss (atrophy) of conchal (turbinate) bone, deviation of nasal septum, and deformation of the nasal bones. AR is an insidious disease that does not produce overt clinical illness or death loss but instead leads to reduced market value, carcass degradation or condemnation, ,and a small body stature. Agents associated with the disease include toxigenic strains of Pasteurella multocida and Bordetella bronchiseptica. The latter colonizes tonsil and the former colonizes the conchal mucosa. Diagnostic tests include immunoassays and nucleic acid hybridization techniques. Preventative measures include improvement of air quality, management, and vaccination.
