Abstract:
Clostridium botulinum type G produces a toxin complex that is composed of neurotoxin, hemagglutinin, and nontoxic nonhemagglutinin. The three genes encoding these proteins were closely linked on a plasmid of about 114 kb (76 MDa) but not on chromosomal DNA. In contrast to the genes of other C. botulinum serotypes, the genes encoding type G toxin are on a plasmid.
