ACTINOMICOSIS MAXILAR CON OBSTRUCCIÓN DE CAVIDADNASAL EN UN TORO DE LIDIA
Abstract
The case of a 3-old-year bullfight that presented a mass in the left maxillary bone is described. The animal had severe breathing difficulty, slight nasal discharge and respiratory sounds acentuated after exercising. At necropsy the mass presented dorsal-rostral expansion, penetrating into the nasal cavity and partially reducing the lumen of with site of 25x10x15 cm. Samples of the mass were taken for histopathology and microbiology. The defi nitive diagnosis was granulomatous osteomyelitis by Actinomyces bovis. In this case, macroscopic and microscopic data were enough for a presuntive diagnosis of bovine actinomycosis and the defi nitive diagnosis was confirmed by the isolation of A. bovis. Actinomycosis has been previously described in the bullfi ght and a differential diagnosis with actinobacillosis, unspecifi c abscesses, tuberculosis and tumoral processes needs to be done. The present case is the first description of maxillary actinomycosis associated with respiratory signs.Downloads
