*Antimicrobial resistance was predicted from genome sequences based on the presence of resistance determinants including mutations and acquired genes. PEN=penicillin, ERY=erythromycin, SXT=co-trimoxazole, FQ=fluoroquinolone, TET=tetracycline, MDR=resistant to ≥3 of these antimicrobials.
†The pre- and post-uptake time periods were defined as in Fig. 1.
‡Total number of pre-uptake isolates for PEN is 204 due to one non-assigned isolate (four intermediate and fully resistant isolates are considered as resistant for SXT).
§Test that the resistance proportion is equal in the pre- and post-uptake periods. P-values were adjusted for multiple testing by the Benjamini–Hochberg procedure.
