FIG. 1.

Dendrogram showing the estimated phylogenetic position of Flectobacillus sp. strain MWH38 within the Cytophaga-Flavobacterium-Bacteroides evolutionary lineage. The dendrogram was generated by using the FITCH algorithm of the PHYLIP package (8) and evolutionary distances (16) calculated from 16S rRNA (and rRNA gene) sequence dissimilarities. The positions of the genera of the Cytophaga-Flavobacterium-Bacteroides evolutionary lineage were calculated from the sequences of the type strains of the type species of the genera.
