Stacked bar graph showing the MIC profile percentages of mcr positive isolates ( n = 41) and mcr negative isolates ( n = 83) screened against colistin, ampicillin, gentamicin and meropenem. Blue denotes isolates sensitive to both colistin and ampicillin, gentamicin or meropenem CS XS. Yellow denotes isolates sensitive to colistin and resistant to ampicillin, gentamicin or meropenem CS XR. Orange denotes isolates resistant to colistin and sensitive to either ampicillin, gentamicin or meropenem CR XS. Pink denotes isolates resistant to both colistin and ampicillin, gentamicin or meropenem CR XR.
