Abstract

Necrotizing pneumonia is a poorly described and rarely reported phenomenon in veterinary medicine. The objective of this case report is to describe the successful management of a case of necrotizing pneumonia in a dog requiring medical and surgical management. This case describes a 9-year-old male neutered Siberian Husky mix that presented to an emergency center for a chronic cough not responsive to antibiotics including doxycycline and amoxicillin-clavulanate. Diagnostic imaging studies were consistent with severe multilobular pneumonia, pleural effusion and secondary pneumothorax. Aerobic culture of a bronchoalveolar lavage sample isolated Escherichia coli that was susceptible to enrofloxacin. A median sternotomy was performed when antibiotics alone were unable to fully clear the infection and the cranial segment of the left cranial lung lobe was removed. Histopathology of this lung lobe indicated subacute suppurative and fibrinohemorrhagic bronchopneumonia with parenchymal and pleural necrosis. The dog survived to discharge with resolution of pneumonia based on thoracic radiographs after 38 days. Necrotizing pneumonia can potentially be adequately treated with appropriate escalation of medical and surgical management.

狗的坏死性大肠杆菌肺炎并发气胸1例。
坏死性肺炎在兽医学中是一种描述不佳且很少报道的现象。本病例报告的目的是描述一例坏死性肺炎的成功管理在狗需要医疗和手术管理。本病例描述了一只9岁的雄性绝育西伯利亚哈士奇混血儿,因慢性咳嗽对抗生素(包括多西环素和阿莫西林-克拉维酸)无反应而来到急救中心。诊断影像学检查与严重的多小叶性肺炎、胸腔积液和继发性气胸一致。支气管肺泡灌洗液需氧培养分离出对恩诺沙星敏感的大肠杆菌。当单纯使用抗生素无法完全清除感染时,行胸骨正中切开术,切除左颅肺叶颅段。肺组织病理学显示亚急性化脓性和纤维蛋白出血性支气管肺炎伴肺实质和胸膜坏死。38 天后,狗存活出院,胸片显示肺炎消退。通过适当的医疗和外科治疗,坏死性肺炎可能得到充分治疗。

期刊介绍: Frontiers in Veterinary Science is a global, peer-reviewed, Open Access journal that bridges animal and human health, brings a comparative approach to medical and surgical challenges, and advances innovative biotechnology and therapy. Veterinary research today is interdisciplinary, collaborative, and socially relevant, transforming how we understand and investigate animal health and disease. Fundamental research in emerging infectious diseases, predictive genomics, stem cell therapy, and translational modelling is grounded within the integrative social context of public and environmental health, wildlife conservation, novel biomarkers, societal well-being, and cutting-edge clinical practice and specialization. Frontiers in Veterinary Science brings a 21st-century approach—networked, collaborative, and Open Access—to communicate this progress and innovation to both the specialist and to the wider audience of readers in the field. Frontiers in Veterinary Science publishes articles on outstanding discoveries across a wide spectrum of translational, foundational, and clinical research. The journal''s mission is to bring all relevant veterinary sciences together on a single platform with the goal of improving animal and human health.
