The pathogenic E. coli strain, serovar 0124 studied in this investigation and its mutants rec A 56 and rec A 441 differ in their ultrastructural organization. In strains having defects in gene rec A, the appearance of intracytoplasmic membranous structures and a great number of extracellular membranous vesicles, as well as the formation of the filamentous forms of cells in the colonies, can be observed. These data indicate that the product of gene rec A plays an active role in the metabolism of bacterial membranes.
本研究中所研究的致病性大肠杆菌菌株，血清型0124及其rec A 56和rec A 441突变体在超微结构组织上存在差异。在rec A基因有缺陷的菌株中，可以观察到胞质内膜结构和大量细胞外膜泡的出现，以及菌落中细胞丝状形态的形成。这些数据表明，rec A基因的产物在细菌膜的代谢中发挥着积极作用。
