16S ribosomal RNA analysis of Filibacter limicola indicates a close relationship to the genus Bacillus.

The phylogenetic relationship of the Gram-negative, filamentous gliding bacterium Filibacter limicola was analysed by 16S rRNA oligonucleotide cataloguing. In contrast to the proposed membership of this asporogenous species in the Flexibacteriaceae, Filibacter limicola clusters phylogenetically with the Gram-positive eubacteria Bacillus pasteurii, Sporosarcina ureae and the asporogenous species Planococcus citreus. The genetic relationship is supported by several common phenotypic properties.
