Pannonibacter phragmitetus, described from a Hungarian soda lake in 2003, had been recognized several decades earlier from human blood cultures as Achromobacter groups B and E.

We performed a polyphasic taxonomic study on isolates previously tentatively classified as Achromobacter groups B and E in comparison with the type strain of Pannonibacter phragmitetus, LMG 22736(T)=NCTC 13350(T). 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 %).

Chryseobacterium joostei sp. nov., isolated from the dairy environment.

Among a large collection of South African dairy isolates, a novel Chryseobacterium taxon (DNA group 3) was previously delineated by a polyphasic taxonomic study (Hugo et al., Syst Appl Microbiol 22, 586-595, 1999). In the present paper, this taxon is further characterized using 16S rDNA sequencing, fatty acid methyl ester analysis and a comparative phenotypic analysis, resulting in the proposal of a novel species, Chryseobacterium joostei sp.
