A 3-year-old 4-kg neutered male domestic shorthair cat died within 5 days after onset of fever and respiratory distress. At necropsy, all tissues were icteric, and the liver had a diffuse reticular pattern. Histologically, hepatitis and encephalitis were associated with Toxoplasma gondii tachyzoites. Toxoplasma gondii female gamonts and oocysts were found in epithelial cells of intact villi and in epithelial cells desquamated into the lumen. Finding of acute hepatitis and T gondii oocysts in an adult cat without detectable immunodeficiency is unusual, because adult cats rarely have clinical signs of toxoplasmosis during the oocyst-shedding phase.
一只3岁、体重4千克的已绝育雄性家养短毛猫在出现发热和呼吸窘迫后5天内死亡。尸检时，所有组织均黄疸，肝脏呈弥漫性网状。组织学上，肝炎和脑炎与刚地弓形虫速殖子有关。在完整绒毛的上皮细胞以及脱落到管腔中的上皮细胞中发现了刚地弓形虫雌配子体和卵囊。在一只无明显免疫缺陷的成年猫中发现急性肝炎和弓形虫卵囊是不寻常的，因为成年猫在卵囊排出阶段很少有弓形虫病的临床症状。
