Recently, it has been shown that two Clostridium butyricum strains (ATCC 43181 and ATCC 43755), isolated from cases of infant botulism, produce a botulinal neurotoxin type E (BoNT/E). Here we have determined the nucleotide sequences of the BoNT/E genes of these two C. butyricum strains and from C. botulinum E strain Beluga. We show that the sequences of the BoNT/E genes from the two C. butyricum strains are identical and differ in only 64 positions resulting in 39 amino acid changes (97% identity at the amino acid level) from that derived from C. botulinum. Our data suggest a transfer of the BoNT/E gene from C. botulinum to the originally nontoxigenic C. butyricum strains.
