Abstract

Using a modified Eckhardt method, we visualized replicons larger than 1,000 kb in strains belonging to both subgroup A and subgroup B. The megaplasmid of CFN299 was characterized. This megaplasmid is different from a cointegrate of various plasmids and from the chromosome. Hybridization of Eckhardt blots of 15 strains with fragments derived from the megaplasmids of the type strains of subgroups A and B revealed that the megaplasmids are subgroup specific.
