Two Strains of E. coli Bacteria (Wild-type and GASP)

Caption

This image shows two strains of E. coli bacteria (wild-type and GASP) competing with each other as they grow out on a flat surface. The wild-type bacteria appear green on the surface while the GASP bacteria appear red. When researchers added the bacteria to more complex microfluidic devices they observed the rapid evolution of different mutations for antibiotic resistance.
