Start date
2007
End date
2010
Objective
1. Develop strains of Escherichia coli O157:H7 and non-pathogenic E. coli that contain the gfp gene inserted into the bacterial chromosome. 2. Determine the survival and growth of gfp-labeled wild type and rpoS-deficient E. coli O157:H7 populations in internalized tissues. 3. Determine differences in the expression of virulence factors in E. coli O157:H7 grown on leafy greens and ground beef.
