摘要

A 1-mo-old reticulated giraffe had progressive anorexia and died at the Ordos Zoo. Autopsy revealed necrotic stomatitis with severe bilateral necroulcerative lesions at the base of the tongue and of the cheeks near the commissures of the mouth. There was also severe bilateral confluent bronchopneumonia with a pronounced bronchial pattern and multifocal fibrinous pleuritis. Histologically, there was serofibrinous-suppurative bronchopneumonia with necrosuppurative bronchiolitis and necrotic arteritis. Filamentous bacteria with morphology consistent with Fusobacterium necrophorum were observed at the advancing edge of the necrotic tissue in the tongue and cheeks, as well as in the affected alveolar spaces and bronchioles. Aggregates of slender, gram-negative, rod-like or filamentous bacteria were identified in the lung impression smear. PCR results of 16S rDNA of the tongue and lung lesions had 100% homology to the F. necrophorum subsp. funduliforme B35 sequence (EF447425.1). The gross, histologic, Gram stain, and PCR product sequencing features in our case were consistent with oral and pulmonary necrobacillosis in ruminants, a rare disease of giraffes.
