Yersinia enterocolitica is a bacterium that causes serious food-borne illness. During infection, Y. enterocolitica tightly attaches to intestinal epithelial cells (IECs). This experiment compares the ability of 3 Y. enterocolitica strains to attach to IECs. “The ability of wild type Y. enterocolitica (WT), a yadA mutant, and a complement strain to attach to IECs was measured.” What is this type of experiment (comparing WT, mutant, and complement) called?
