mcr-1 increases bacterial resistance to human antimicrobial peptides. 2.107E. coli mcr-1+ or 2.107E. coli mcr-1- were incubated for 2 h with α-defensins (hBD1 to 3), β-defensins (HD-5 and -6), and cathelicidin (LL-37). The numbers of surviving bacteria are reported as the number of colony-forming units (CFUs). Data are means ± SEMs of four replicates and are representative of three independent experiments
