[A unique marker of Pseudomonas from the first group of rRNA homology--selective sensitivity to the bacteriostatic action of barium ions].
On the basis of the study of the bacteriostatic action of chlorides and nitrates of barium and 24 other metals on 18 Pseudomonas species of all groups of rRNA homology and on 49 bacterial species belonging to 25 other genera, unique selective sensitivity to the bacteriostatic action of Ba2+ ions has been established in Pseudomonas of the first group of rRNA homology. The marker of barium sensitivity is in line with changes in the classification of Pseudomonas and is of interest for their further more precise systematization. The test for barium sensitivity of bacteria helps simplify the identification of Pseudomonas of the first group of rRNA homology and makes the identification more accurate.
