An unidentified coccidium was found in the brain and the heart of a 6-year-old female cat. Tissue cysts measured 40-130 x 40-112 microns and contained hundreds of bradyzoites measuring 4.2-5.2 x 1.2-1.8 microns. The cyst wall was 0.26-0.53 microns thick. Tissue cysts reacted positively with anti-Toxoplasma gondii serum but not with anti-Neospora caninum serum in an immunohistochemical test. Ultrastructurally, the cyst was aseptate and contained banana-shaped bradyzoites. Micronemes and rhoptries in bradyzoites were unlike those found in T. gondii bradyzoites. In the unidentified coccidium, the micronemes were arranged in rows and the rhoptries extended from the anterior tip to the posterior end.
在一只6岁雌性猫的大脑和心脏中发现了一种未鉴定的球虫。组织囊肿大小为40 - 130×40 - 112微米，含有数百个缓殖子，缓殖子大小为4.2 - 5.2×1.2 - 1.8微米。囊肿壁厚度为0.26 - 0.53微米。在免疫组织化学试验中，组织囊肿与抗刚地弓形虫血清呈阳性反应，但与抗犬新孢子虫血清无反应。超微结构上，囊肿无隔膜，含有香蕉形缓殖子。缓殖子中的微线体和棒状体与刚地弓形虫缓殖子中的不同。在这种未鉴定的球虫中，微线体呈排状排列，棒状体从前端延伸至后端。
