Abstract:
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.
