Five-day-old neonatal piglets presented with debilitation and ananastasia. At the necropsy of one piglet, the apex of the tongue was found to be discolored dark red, and disseminated white foci were found on the cut surface. Many white foci were also found in the lungs and on the serosa of the liver and spleen. Histopathological findings revealed multifocal necrotic glossitis and pneumonia with Gram-negative bacilli. The bacilli were identified as Actinobacillus suis through immunohistochemical, biochemical, and genetic tests, including 16S rRNA gene sequencing. Although A. suis usually causes inflammation in thoracic and abdominal organs, lesions were also found in the tongue in the present case. This study is the first report of glossitis caused by A. suis.
5日龄新生仔猪出现虚弱和死亡。对一头仔猪进行尸检时，发现舌尖变色呈暗红色，切面有散在的白色病灶。在肺以及肝和脾的浆膜上也发现了许多白色病灶。组织病理学检查结果显示为多灶性坏死性舌炎和伴有革兰氏阴性杆菌的肺炎。通过免疫组织化学、生化和基因检测，包括16S rRNA基因测序，将这些杆菌鉴定为猪放线杆菌。虽然猪放线杆菌通常引起胸腹部器官炎症，但本病例中在舌部也发现了病变。本研究是猪放线杆菌引起舌炎的首次报道。
