Three 7-wk-old Bobwhite quail were submitted for necropsy to the Douglas branch of the Georgia Poultry Laboratory Network. Grossly, one bird had multiple white foci in the liver and a mild airsacculitis. In this quail there were multiple hepatic granulomas that contained mats of filamentous bacteria easily seen in hematoxylin- and eosin-stained histologic sections. These bacteria were negative with period acid-Schiff and were not acid fast. Bacteria were gram-positive but were most evident on Warthin-Starry silver-stained sections. The appearance and histochemical characteristics of these bacteria are most consistent with Eubacterium tortuosum.
三只7周龄的美国鹧鸪被送到佐治亚州家禽实验室网络的道格拉斯分部进行尸检。大体上，一只鸟的肝脏有多个白色病灶，并有轻度气囊炎。在这只鹧鸪中，有多个肝脏肉芽肿，其中含有在苏木精和伊红染色的组织切片中容易看到的丝状细菌团块。这些细菌过碘酸-希夫染色呈阴性，且抗酸染色阴性。细菌革兰氏阳性，但在Warthin-Starry银染色切片上最为明显。这些细菌的外观和组织化学特征与曲折真杆菌最为一致。
