Peritonite piogranulomatosa por Nocardia spp. em cão : relato de caso

Abstract

Nocardiosis is caused by an aerobic, gram-positive, ramificated and filamentous bacteria of Nocardia genus, subgroup Actinomycetos. The diagnosis depends on the characterization of the inflammatory lesions with the morphologically compatible microorganism associated with microbiological and molecular isolation and identification. The objective of this work is to report a case of nocardiosis in a canine that developed peritoneal pyogranulomatous inflammation six months after ovariosalpingohisterectomy. Despite the therapeutic procedures and clinical alterations the dog died. Morphologically, piogranulomatous peritonitis was the main anatomopathological alteration which was associated with Nocardia spp. Molecularly, this species resembles the N. concava species through phylogenetic analysis. N. concava was described as a cause of infection in humans in the Asia, however, there are no records in the literature on the canine species, being this the first report.
