Draft Genome Sequences for Dual-Toxin-Producing Clostridium botulinum Strains

ABSTRACT Here, we present draft genome sequences for three Clostridium botulinum strains that produce multiple botulinum toxin serotypes. Strains that produce two toxins are rare; however, one of these strains produces subtype B5 and F2 toxins, and two of the strains produce subtype A4 and B5 toxins.
