The column denoted “Discharge (Adm-)” contains isolates which are a subset of all the discharge-isolates, the isolates in this column are from patients which had faecal samples at the admission screening which tested negative for carbapenem-resistant K. pneumoniae. The column denoted “Others” summarizes isolates from all unique STs to which only a single isolate was found to belong. The column denoted “Inconclusive” summarizes isolates for which the whole-genome sequencing data obtained could not be used to conclusively determine the K. pneumoniae ST
