Comparative 16S rRNA gene sequence analysis suggested that strains of Achromobacter groups B and E belong to P. phragmitetus (similarity levels were higher than 99 %). DNA–DNA hybridization experiments and other genotypic and phenotypic analyses confirmed that the three taxa represent a single species. Whilst P. phragmitetus was described in 2003 from a Hungarian soda lake, it had been observed in human blood cultures in the UK since 1975. We present here the characteristics of the organism to facilitate its recognition in human clinical specimens and hence to determine its clinical significance., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64563-0
