Patient transmission dynamics of local bacteria samples. The bla _NDM cases were identified in a local hospital from 2010 to 2011 as represented in the timeline. Each patient is represented by a horizontal track. Subject ID, sample ID and bla _NDM-positive plasmid found in the isolate are indicated in the first 3 columns. Patient’s stay in the same ward is denoted by gray box. Only wards with ≥2 reported bla _NDM cases are indicated in the diagram. *: closest reference plasmid identified based on minimum 75 % sequence coverage
