This bacteria is a common source of urinary tract infections.
Richard Lenski has been running a long term experiment on this species's evolution. The Lederbergs conducted experiments on auxotrophic (OX-oh-TROFF-ick) strains of this bacteria. This bacteria is a common source of urinary tract infections. A safe strain of this bacteria is K12, while one of the more problematic strains of this bacteria is O157:H7.
