Antimicrobial resistance genes carried by mcr-positive E. coli isolates. A Heat map showing detected antimicrobial resistance genes carried by the isolates. Small boxes marked in red and green represent positive and negative, respectively. B Column chart showing numbers of isolates positive for different detected antimicrobial resistance genes. Antimicrobial resistance genes accounting for resistance to the same antibiotic class are marked with columns in the same color
