The fine structure of a series of stalked bacteria belonging to the genera Caulobacter and Asticcacaulis has been examined in thin sections. The cell wall has the multilayered structure typical of many Gram-negative bacteria, and continues without interruption throughout the length of the stalk. The core of the stalk, continuous with the cytoplasmic region of the cell, is enclosed in an extension of the cell membrane, and contains a system of internal membranes: it is devoid of ribosomes and nucleoplasm. A membranous organelle occupies the juncture of stalk and cell, separating the ribosomal region from the core of the stalk. Typical mesosomes also occur in the cell, being particularly frequent at the plane of division. The secreted holdfast is located at the tip of the stalk in Caulobacter, and at the pole of the cell adjacent to the stalk in Asticcacaulis.
对一系列属于柄杆菌属和星状柄杆菌属的有柄细菌的精细结构进行了薄切片检查。细胞壁具有许多革兰氏阴性细菌典型的多层结构，并且在柄的整个长度上连续不间断。柄的核心与细胞的细胞质区域相连，被细胞膜的延伸部分包围，并包含一个内膜系统：它没有核糖体和核质。一个膜性细胞器占据柄和细胞的连接处，将核糖体区域与柄的核心分开。典型的中体也出现在细胞中，在分裂平面处尤为常见。在柄杆菌属中，分泌的固着器位于柄的尖端，而在星状柄杆菌属中，位于与柄相邻的细胞极。
