The tonsils of ten fattening pigs were compared with those of ten breeding sows to determine the relative incidence of Tonsillophilus suis and Actinomyces sp lesions. Macroscopic observation revealed mildly focal upheavals on the tonsillar mucosal surfaces of two of the breeding sows. In tonsillar slices from both pig groups, tiny nodules containing sulfur granules were found. Histopathologically, the T. suis and Actinomyces sp lesions were noted as tonsillar crypt abscesses in both pig groups, and granulomas due to T. suis were seen in the breeding sows. T. suis showed larger 'club-shaped' structures than Actinomyces sp, characterized as clubs showing a broom-like structure with degenerated central thalli. Breeding sows are known to have a higher incidence of tonsillar T. suis lesions than fattening pigs, and in this study, those fattening pigs showing greater propensity to infection by Actinomyces sp also showed a mixed infection with T. suis that produced the tonsillar crypt abscesses. In addition, it is known that in breeding sows, the T. suis lesion develops from a crypt abscess into a granuloma.
将十头育肥猪的扁桃体与十头繁殖母猪的扁桃体进行比较，以确定猪扁桃体杆菌（Tonsillophilus suis）和放线菌属（Actinomyces sp）病变的相对发生率。宏观观察发现，两头繁殖母猪的扁桃体黏膜表面有轻度局灶性隆起。在两组猪的扁桃体切片中，均发现了含有硫磺颗粒的小结节。组织病理学上，两组猪的猪扁桃体杆菌和放线菌属病变均表现为扁桃体隐窝脓肿，繁殖母猪中可见由猪扁桃体杆菌引起的肉芽肿。猪扁桃体杆菌显示出比放线菌属更大的“棒状”结构，其特征为呈扫帚状结构且中央菌体退化的棒状体。已知繁殖母猪扁桃体猪扁桃体杆菌病变的发生率高于育肥猪，在本研究中，那些更容易感染放线菌属的育肥猪也表现出与猪扁桃体杆菌的混合感染，从而导致扁桃体隐窝脓肿。此外，已知在繁殖母猪中，猪扁桃体杆菌病变会从隐窝脓肿发展为肉芽肿。
