In an effort to establish comparative data within the genus Leucocytozoon, elongate gametocytes of L. ziemanni from naturally infected great horned owls (Bubo virginianus) were examined by electron microscopy. Micro- and macrogametocytes proved to be easily distinguishable at the electron microscopic level due to dramatic dimorphism at maturity and cytoplasmic and nuclear morphology. The parasite membrane architecture, number and type of cytoplasmic ribosomes of both micro- and macrogametocytes, presence and arrangement of osmiophilic bodies and electron dense spheres, mitochondrial morphology, endoplasmic reticulum cisternae morphology, mitochondria containing pocket infoldings of the nuclear membrane of the microgametocytes, and cytostome and food vacuole formation compare favorably with available information on L. simondi and L. smithi. Comparative variations exist only in that L. ziemanni gametocytes apparently lack compartmentalization of the cytoplasm by aligned unit membranes and parasite induced separations of the host cell nucleus as reported for L. simondi.
为了在白细胞虫属中建立比较数据，利用电子显微镜对自然感染的大角鸮（Bubo virginianus）体内的齐氏白细胞虫（Leucocytozoon ziemanni）的细长配子体进行了检查。由于成熟时显著的二态性以及细胞质和细胞核形态，在电子显微镜水平下，小配子体和大配子体很容易区分。小配子体和大配子体的寄生虫膜结构、细胞质核糖体的数量和类型、嗜锇体和电子致密球的存在及排列、线粒体形态、内质网池形态、小配子体线粒体包含的核膜袋状内褶，以及胞口和食物泡的形成，与关于斯氏白细胞虫（Leucocytozoon simondi）和史密斯白细胞虫（Leucocytozoon smithi）的现有信息相比具有优势。比较差异仅在于，齐氏白细胞虫配子体显然缺乏如斯氏白细胞虫报道的那样由排列的单位膜对细胞质进行的区室化以及寄生虫诱导的宿主细胞核分离。
