atrophic rhinitis

noun

1

: chronic inflammation of the mucous membrane of the nose resulting in atrophy and sclerosis of the nasal mucosa

especially : ozena

The cause of atrophic rhinitis is unknown, with the leading theory being age-related mucosal atrophy, sometimes complicated by secondary bacterial infection.

2

: a chronic disease of swine that is characterized by purulent inflammation of the nasal mucosa, atrophy of the nasal conchae, and abnormal swelling and distortion of the face

The severity of atrophic rhinitis in a herd depends largely on the presence of toxigenic strains of P multocida [Pasteurella multocida], the level of management, and the immune status of the herd.
