Tyzzer's disease (bacillus pilirformis infection) was diagnosed in young guinea pig killed because of diarrhea and poor condition. There was necrosis and inflammation of the colon, cecum and ileum. Typical B. piliformis were in intestinal epithelial cells. Spirochetes were in large numbers in intestinal crypts and were often adjacent to the intracellular B. piliformis. Extracellular B. piliformis occasionally were surrounded by spirochetes.
泰泽氏病（毛样芽孢杆菌感染）在一只因腹泻和身体状况不佳而死亡的幼年豚鼠身上被诊断出来。结肠、盲肠和回肠出现坏死和炎症。典型的毛样芽孢杆菌存在于肠道上皮细胞中。螺旋体大量存在于肠隐窝中，且常常与细胞内的毛样芽孢杆菌相邻。细胞外的毛样芽孢杆菌偶尔被螺旋体包围。
