Isolates used for invasion assay are marked with a, isolates with completed whole genome sequences are marked with b, isolates were IncFIB and IncI1 replicons were identified by PCR and sequencing are marked with c (which could indicate the presence of both an IncI1 and an IncFIB plasmids or the presence of a cointegrated plasmid).
