Timeline of results for ESBL-positive E. coli participants. Each row represents an ESBL-positive E. coli participant (P) and their culture results for ESBL E. coli and non-ESBL E. coli over 27 weeks. Each positive week is shown by a capsule of two halves, the left side representing isolation of ESBL E. coli and the right side non-ESBL E. coli. Results shown are for stool culture, with the exception of yellow dotted half-capsules, which represent ESBL-positive E. coli catheter urine (P3 and P6), and red dotted half-capsules (P3 and P6), which represent a positive stool and urine sample in the same week. Capsules are coloured by ESBL E. coli (red: ST131 ESBL E. coli, orange: ST38 ESBL-E. coli) and non-ESBL E. coli (dark blue: ST131 non-ESBL E. coli; light blue: non-ST131 non-ESBL E. coli). White asterisk, ST not known as sequencing failed to generate high quality data; black square, sample taken but no E. coli isolated; dashed line, not yet recruited into the study or no longer enrolled. Numbers shown for non-ESBL E. coli represent MLST sequence type
