Representative highly radiation-resistant Moraxella-Acinetobacter (M-A), Pseudomonas radiora, Micrococcus radiodurans, and Micrococcus radiophilus exhibited a wide variety of division systems and cell wall characteristics. However, the most resistant M-A possessed unusually thick cell walls, indicating a possible role of the cell wall in radiation resistance in the M-A. Thick septation was present in most of the bacteria studied, but was absent in P. radiora, thus excluding this as a necessity for high resistance. Reliable determination of the number of division planes of the M-A for use as a taxonomic criterion was achieved by the direct observation of dividing cells. The highly resistant M-A were found to divide in multiple planes and had base compositions of 54.0 to 57.5%, unlike typical Moraxella and/or Acinetobacter species. The taxonomic position of most highly resistant bacteria remains unclear.
具有代表性的高度耐辐射的莫拉克斯氏菌-不动杆菌（M-A）、耐辐射假单胞菌、耐辐射微球菌和嗜辐射微球菌表现出多种分裂系统和细胞壁特征。然而，最具抗性的M-A具有异常厚的细胞壁，这表明细胞壁在M-A的抗辐射能力中可能发挥作用。在大多数所研究的细菌中存在厚的隔膜，但耐辐射假单胞菌中不存在，因此排除了其作为高抗性的必要条件。通过直接观察分裂细胞，可靠地确定了用作分类标准的M-A的分裂平面数量。发现高度抗性的M-A在多个平面上分裂，碱基组成在54.0%至57.5%之间，这与典型的莫拉克斯氏菌和/或不动杆菌属不同。大多数高度抗性细菌的分类地位仍不清楚。
