FIG. 3.
Southern blot analysis of chromosomal DNA preparations from C. jejuni wild-type and galE mutant strains. Chromosomal DNAs were digested with HindIII, resolved by agarose gel electrophoresis, and probed with plasmid pBF84Bnd17 containing the C. jejuni galE gene. Lane 1, wild-type strain 81116; lane 2, strain 81116galEa; lane 3, strain 81116galEb.
