Abstract: Bovine nasal granuloma (chronic granular rhinitis) is a chronic proliferative rhinitis of common and apparently unique occurrence in Australasian cattle (Gallagher, 1972; Hore et al 1973). The disease is characterized by the presence of numerous nodules, 1 to 4 mm in diameter on the mucous membrane of the anterior third of the nasal cavity (Gorrie, 1961). Evidence for the role of viruses, particularly infectious bovine rhinotracheitis (IBR) virus, in the aetiology of this disease is equivocal (Curtis and Sutton, 1972). No clear association between the acute catarrhal rhinitis caused by the IBR virus (Webster and Manktelow, 1959) and bovine nasal granuloma, has been demonstrated. The presence of large numbers of eosinophils in nasal scrapings (Curtis and Sutton, 1972), and also the marked infiltration of eosinophils into the nasal mucosa of affected animals (Pemberton and White, 1974) strongly suggest that bovine nasal granuloma is an allergic disease. However, the nature of the allergen or allergens has yet to be determined. The foIllowing is a report of recent observations made during an epidemic of severe rhinitis in a group of calves on a Bay of Plenty farm.
