Present case report describes a case of an atypical oesophageal actinobacillosis in an adult cow presented to the university hospital with a history of inability to drink and swallow. Clinical examination revealed a five-inch swelling in the jugular groove. Skiagram revealed the presence of a small and slightly radio opaque round growth. Exploratory surgical excision of the growth was adapted as palliative treatment and the extirpated tissue was fixed in 10% buffered formalin. Histopathological examination revealed pyogranulomatous inflammation with radiating eosinophilic club shaped bodies surrounding small colonies of coccobacilli. Gram and Ziehl-Neelsen stains confirmed the presence of Gram-negative and non-acid-fast coccobacilli. Histopathology confirmed the pathognomonic lesion and proved to be a modality of choice for pathologists to reach at a diagnosis of atypical oesophageal actinobacillosis in a cow. After the exhaustive search of relevant literature on atypical actinobacillosis, the authors claim this to be the second report of oesophageal actinobacillosis worldwide.
本病例报告描述了一头成年奶牛患非典型食管放线菌病的病例，该奶牛被送至大学医院，有无法饮水和吞咽的病史。临床检查发现颈静脉沟处有一个5英寸的肿胀。X线片显示有一个小的、略不透射线的圆形肿物。对该肿物进行探索性手术切除作为姑息性治疗，切除的组织固定在10%缓冲甲醛中。组织病理学检查显示为脓性肉芽肿性炎症，有放射状嗜酸性棒状体围绕小的革兰氏阴性球杆菌菌落。革兰氏染色和齐-尼氏染色证实存在革兰氏阴性且抗酸染色阴性的球杆菌。组织病理学证实了特征性病变，并且被证明是病理学家诊断奶牛非典型食管放线菌病的一种首选方法。在对非典型放线菌病的相关文献进行详尽检索后，作者声称这是全球第二例食管放线菌病报告。
