Lamellae of cytopharynx in the opisthe of a dividing cell. This cytopharynx is not yet functional and lacks most of the medium dense vesicles that accumulate between the lamellae. Toxicysts are present. One toxicyst has myelin-like layers at the level it was sectioned. Bacteria align adjacent to the cell. they may be symbiotic. TEM taken on 5/9/69 by M. Sage with Philips 300 operating at 60kV. Neg. 9,250X. Bar = 1µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. A high resolution image is in the library (CIL:38864) and is available for quantitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness.

该细胞后肠的细胞质内褶结构。该细胞质内褶尚未发挥功能，其间未积聚大多数中等密度的泡状结构。存在毒素囊。其中一个毒素囊在切片处具有类似髓鞘的层状结构。细菌排列在细胞附近，它们可能是共生关系。于1969年5月9日由M. Sage使用Philips 300型电镜，在60kV的电压下进行透射电镜（TEM）拍摄。负片放大倍数为9,250倍。标尺长度为1微米。负片被打印到纸上，图像被扫描到Photoshop中。此数字化图像可用于定性分析。高分辨率图像存档于图书馆（CIL:38864），可用于定量分析。采用标准戊二醛固定，随后用四氧化锇处理，经酒精脱水并嵌入环氧树脂中。使用切片机制备的切片厚度约为75纳米。更多信息可参考（http://www5.pbrc.hawaii.edu/allen/）。
