Cluster distribution and persistence. Left: strain-distinct cultured isolates of E. coli , K. oxytoca and K. pneumoniae from sink drain aspirates sampled over 12 weeks across three hospital wards. Different colours indicate distinct strains (defined by 100 SNP clusters), and cefpodoxime-resistant and/or selected ESBL-positive isolates are indicated by filled markers. Right: persistence of sink and contemporaneous patient E. coli strains throughout the sampling period.
