A new type of inclusion in blue-green algae termed a wall body is described. These are elongate bodies of medium electron density, from 6 to 70 nm in thickness and at least 0.2 micrometer in depth found in large cells of Anabaena sp. B387. The bodies are up to 12 micrometer long, extending the complete length of the cell in some cases. Some of the bodies are bifurcated and the ends appeared to come in contact with the plasma membrane. The wall bodies lie at various angles in the cells. Up to six have been observed in a single thin section of a cell. The large cells are found in greater numbers in cultures grown in a medium solidified with agar. Comparison of the bodies to the mucopolymer layer (layer 2) of the cell wall is made.
描述了一种在蓝藻中被称为壁体的新型内含物。这些是中等电子密度的细长体，厚度为6至70纳米，在鱼腥藻B387的大细胞中深度至少为0.2微米。这些体长达12微米，在某些情况下延伸整个细胞长度。一些体是分叉的，其末端似乎与质膜接触。壁体在细胞中以不同角度存在。在细胞的单个薄切片中最多观察到六个。在琼脂固化培养基中培养的培养物中发现大量大细胞。将这些体与细胞壁的粘多糖层（第2层）进行了比较。
