Genetic interrelationships of saccharolytic Clostridium botulinum types B, E and F and related clostridia as revealed by small-subunit rRNA gene sequences
The phylogenetic interrelationships of saccharolytic C. botulinum types B, E and F together with eleven other saccharolytic clostridia were examined by 16S rRNA gene sequencing. Comparative analysis of the sequence data revealed that the saccharolytic C. botulinum types B, E and F were highly related and represents a single genetic group. Strains of C. barati and C. butyricum that produce botulinal neurotoxin revealed almost 100% 16S rRNA sequence identity with their respective non-toxigenic counterparts and were phylogenetically distinct from saccharolytic C. botulinum (types B, E and F). Proteolytic C. botulinum type F was shown to be phylogenetically remote from the saccharolytic C. botulinum group. The implications of the sequence data for the taxonomy of the C. botulinum complex are discussed.
