The ultrastructure of Pseudomonas pseudomallei, Pseudomonas aeruginosa. Yersinia pseudotuberculosis, Salmonella typhimurium, Listeria monocytogenes was studied after treatment with EDTA. The study established that the most sensitive species were: Pseudomonas pseudomallei and Pseudomonas aeruginosa. In the case of Listeria monocytogenes changes were not observed. Typical ultrastructural changes in the cell wall and the cytoplasmic membrane were established by means of ultrathin sections, as well as with scanning electron microscopy of Pseudomonas pseudomallei and Pseudomonas aeruginosa.
在用乙二胺四乙酸（EDTA）处理后，对类鼻疽假单胞菌、铜绿假单胞菌、假结核耶尔森菌、鼠伤寒沙门氏菌、单核细胞增生李斯特菌的超微结构进行了研究。该研究确定，最敏感的菌种是：类鼻疽假单胞菌和铜绿假单胞菌。在单核细胞增生李斯特菌的情况下未观察到变化。通过超薄切片以及类鼻疽假单胞菌和铜绿假单胞菌的扫描电子显微镜观察，确定了细胞壁和细胞质膜的典型超微结构变化。
