| Abstract: | The study of negatively contrasted preparations was made with the aim of of finding out the possibility of identifying Ps. aeruginosa by the number and location of flagella. 4,800 bacteria were studied by means of an electron microscopy, type JEM-100; of these, 2,443 bacterium had a single polar flagellum, 414 bacteria had 2 and 138 bacteria had 3 polar flagella, while 1,805 cells had no flagella. The presence of bipolar flagella and pili, as well as nonflagellate Ps. aeruginosa cultures, was revealed. The possibility of the existence of noncapsular and capsular forms in one and the same Ps. aeruginosa strain was shown. The use of these data in the systematics of Ps. aeruginosa is anticipated. |
