  1. aBacterial growth levels in 10 μl spot denoted by: +++ = lawn growth; ++ = 20–100 colonies; + = 4–20 colonies.
  2. bResults for SNP analysis of DNA from the duplicate cultures are given.
  3. cAlso detected when grown without colistin selection.
  4. dNot detected when grown without colistin selection.
  5. eAnnotated as “rstA regulator” or BN373_26561 (from positions 2777167–2778228 in Ecl8).
  6. NB: The bold represent when the samples were extracted for sequencing.
