pubmed:abstractText |
To clarify the intra- and intergeneric relationships of the genus Cytophaga, 16S rRNA sequences and respiratory isoprenoid quinones were determined for the type strains of the 21 validly published species and one isolate in the genus Cytophaga. The sequence analysis revealed extreme heterogeneity of this genus, which diverged into nine distinct lines of descent. Each lineage of Cytophaga was characterized by possessing either menaquinone-6 (MK-6) or MK-7. The MK-6-possessing species were located in the two lineages that were remote from MK-7 species. One of the MK-6 lineages was composed only of terrestrial species and the other only of marine species. Flavobacterium aquatile, the type species of the genus Flavobacterium, was located in the MK-6 terrestrial lineage. The terrestrial Cytophaga species with MK-6 should be transferred to the genus Flavobacterium. The marine facultative anaerobes with MK-7 were located in the bacteroides branch, and possessed signature sequences with features intermediate between the bacteroides and the flavobacteria subdivisions. Cytophaga hutchinsonii, the type species of the genus Cytophaga, had a close relationship only with Cytophaga aurantiaca. The genus Cytophaga should be restricted to these two cellulose-degrading species. The genus Cytophaga is so heterogeneous that it should be divided into several genera and higher taxa in accordance with the phylogenetic relationships.
