Fig. 1. Location of the four sampling sites in Georgia and Idaho. The distance among the three Georgia locations is shown; the distance between Kimberly, ID, and the three Georgia locations is approximately 2900 km. At each location, isolates of Escherichia coli were obtained from cattle, horse, and swine. Because of the importance of broiler production in Georgia, chickens were also sampled at the three locations in Georgia.
