R-bodies in Pseudomonas aeruginosa strain 44T1.

For the first time R-bodies are described in a new strain 44T1 of Pseudomonas aeruginosa. Its size was measured as being 0.22 to 0.37 microns of width per 0.27 to 0.41 microns of length and 5 to 9 spiral turns about 16 nm. These structures are similar to previously observed in bacteria and are related with physiological state of bacteria in minimal conditions of growth.
