Abstract

The nearly complete small subunit 16S ribosomal RNA (rRNA) gene sequence amplified by polymerase chain reaction was determined for Flavobacterium psychrophilum (formerly Flexibacter psychrophilus) by using automated nucleotide sequencing. The sequence was found to be 1,465 base pairs (bp) in length, a size consistent with previously determined sequences for 14 other bacterial species from various taxa, including the yellow-pigmented bacteria. Sequence signatures confirmed that this organism was a member of the bacterial division Bacteroides-Flavobacterium. Parsimonious and additive phylogenetic trees were constructed with homology, and pairwise evolutionary distances, were used to estimate phylogenetic relationships. Data show that F. psychrophilum, F. columnare, and Flexibacter maritimus are closely related, have a common descent, and represent a distinct group within the division Bacteroides-Flavobacterium. This group also included other organisms from the genera Flavobacterium and Cytophaga. Further, Flavobacterium aquatile, the type species For the genus Flavobacterium, was also determined to be a member of this "Flavobacterium-Cytophaga-Flexibacter subcomplex. " This supports previous assertions that the type strain of Flavobacterium should be changed to a more representative species such as Flavobacterium breve.
