In this report, cases of avian mycobacteriosis in two lofts of racing pigeons are described. Three racing pigeons of 2-year old from the first loft (A) and four racing pigeons of 4-5 years old from the second loft (B) were submitted to the Unit of Avian Medicine for clinical examination and necropsy. In the case history chronic and debilitating disease was reported. The clinical signs included emaciation, depression, lameness, periorbital swelling and diarrhea, although the appetite was normal. Post mortem lesions involved an enlarged spleen with multiple different sized yellow nodules. Similar lesions were also observed in the liver, conjunctiva of the inferior eyelids and in the femoral bone marrow. The suspicion of avian mycobacteriosis was based on history, clinical signs and typical lesions. In order to confirm the diagnosis, histopathology was performed on tissue sections and revealed the presence of multiple granulomas with central necrosis. In addition, Ziehl-Neelsen positive bacilli were observed in histological sections and smears from the granulomas of the affected tissues. Molecular analysis identified the causative agent as subsp. . This is the first case report of avian mycobacteriosis in Greece, which describes the presence of granulomatous conjunctivitis and the molecular identification of subsp. as the causative agent in racing pigeons.
在本报告中，描述了两个赛鸽鸽舍中的禽分枝杆菌病病例。来自第一个鸽舍（A）的3只2岁赛鸽和来自第二个鸽舍（B）的4只4至5岁赛鸽被送至禽医学科进行临床检查和尸检。病史报告显示为慢性消耗性疾病。临床症状包括消瘦、抑郁、跛行、眶周肿胀和腹泻，尽管食欲正常。尸检病变包括脾脏肿大，有多个大小不同的黄色结节。在肝脏、下眼睑结膜和股骨骨髓中也观察到类似病变。基于病史、临床症状和典型病变怀疑为禽分枝杆菌病。为了确诊，对组织切片进行了组织病理学检查，结果显示存在多个伴有中央坏死的肉芽肿。此外，在受影响组织肉芽肿的组织学切片和涂片中观察到齐-尼氏阳性杆菌。分子分析确定病原体为亚种。这是希腊禽分枝杆菌病的首例病例报告，描述了肉芽肿性结膜炎的存在以及亚种作为赛鸽病原体的分子鉴定。
