A not pregnant 4-year-old Jersey cow was presented with the sudden appearance of respiratory noise, nasal discharge and moderate respiratory difficulty. Upon physical examination a snoring-like noise, extended head and neck position, exaggerated abdominal effort, bilateral nasal discharge and left prescapular lymph node enlargement were noted. Sub-occlusion of the initial portion of the respiratory tract was suspected. Radiographic and endoscopic examinations revealed a pedunculate mass on the dorsal aspect of the rhinopharynx, which was removed with endoscopically assisted electrosurgery. Histologic examination revealed a chronic pyogranulomatous inflammation with eosinophilic club-like bodies surrounding small colonies of rod-shaped bacteria. Results of histochemical staining were consistent with Actinobacillus-like bacteria and a diagnosis of respiratory actinobacillosis was reached. Surgery and antibiotic therapy were resolutive, as demonstated by an endoscopic check at the second month after surgery, even without the association of the traditional iodine cure, which is regarded as the treatment of choice for actinobacillosis.
一头4岁未怀孕的泽西奶牛出现了突然的呼吸杂音、鼻分泌物和中度呼吸困难。体格检查时发现有类似打鼾的声音、头颈伸展姿势、腹部用力夸张、双侧鼻分泌物以及左肩胛前淋巴结肿大。怀疑呼吸道起始部分存在部分阻塞。放射学和内镜检查显示鼻咽背侧有一个带蒂肿物，通过内镜辅助电外科手术将其切除。组织学检查显示为慢性脓性肉芽肿性炎症，嗜酸性棒状体围绕着小的杆状细菌菌落。组织化学染色结果与类放线杆菌一致，诊断为呼吸道放线杆菌病。手术和抗生素治疗有效，术后第二个月的内镜检查证实了这一点，即使未联合传统的碘治疗，而碘治疗被认为是放线杆菌病的首选治疗方法。
