JF International Journal of Systematic and Evolutionary Microbiology, VO 34 IS 4 SP 492 OP 495 DO https://doi.org/10.1099/00207713-34-4-492 PB Microbiology Society, SN 1466-5034, AB The necessity to rename strain ATCC 27377T (T = type strain), Pasteuria ramosa sensu Staley, led Starr and his associates to propose placing this organism in the genus Planctomyces. Morphological and physiological observations, as well as deoxyribonucleic acid base composition and 16S ribosomal ribonucleic acid oligomer analyses, clearly showed that strain ATCC 27377T differs significantly from species belonging to the genus Planctomyces. Therefore, we propose that strain ATCC 27377T be renamed Pirella staleyi and afforded the position of the type strain of the type species of the newly created genus Pirella. The generic and species descriptions are emended. The request of Starr et al. (Int. J. Syst. Bacteriol. 33:666–671, 1983) for the conservation of Pasteuria ramosa is supported., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-34-4-492
