The mucosal surfaces of villi from the small intestine of cats infected with Toxoplasma gondii were studied with the scanning electron microscope and compared with those from uninfected control cats. In uninfected cats villi were predominantly leaf shaped and were lined with ridges; goblet cell openings could be seen. The enterocytes had a hexagonal surface outline and were dome-shaped. Infected cats had both normal and abnormal villi. Injured villi were shortened and attained a broad leaf shape, often with blunt edges. Enterocytes containing oocysts were enlarged, and microvilli were resolvable only on these surfaces. Ruptured cells from which parasite discharge had occurred were seen. Oocysts were observed and possessed a smooth coat.
用扫描电子显微镜研究了感染刚地弓形虫的猫小肠绒毛的黏膜表面，并与未感染的对照猫的小肠绒毛进行了比较。在未感染的猫中，绒毛主要呈叶状，表面有嵴；可见杯状细胞开口。肠上皮细胞表面呈六边形，呈圆顶状。感染的猫既有正常的绒毛，也有异常的绒毛。受损的绒毛缩短，呈宽叶状，边缘常钝圆。含有卵囊的肠上皮细胞肿大，仅在这些表面可分辨出微绒毛。可见发生寄生虫排出的破裂细胞。观察到卵囊，其表面光滑。
