Escherichia coli Genome sequencing
Comparison of SNPs differences among three E. coli strains. The three strains were: wild-type sensitive E. coli (E. coli-S); resistant strains (E. coli-R): obtained by antibiotic domestication of E. coli-S, and E. coli-D: resistant bacteria derived from the loss of resistance phenotype in an antibiotic-free environment.
