FIG. 6.

Mapping the location of the vtp gene with type-specific DNA probes. Plasmids from B. hermsii representing five of the Vtp types are shown in the agarose gel in the left panel. Southern blots containing these DNAs probed with different vtp probes are shown in the other panels, demonstrating their specificity. The isolate source for the DNA is shown above each lane along with its genomic group. The origins of the probes and Vtp types are shown below each panel. Molecular size standards (MSS) are shown on the left in kilobases.
