Whole-genome sequencing distinguished sewer water and WWTP-influent E. coli across sample type and collection date. AMR profiles of wastewater E. coli isolates (n = 21) are organized by sample type (sewer water versus wastewater treatment plant influent) and are further categorized by sample collection date. Antimicrobial function and subclass of gene family names were used to group resistance genes. For each isolate, green boxes indicate gene presence and beige boxes indicate gene absence. Isolate #: the unique identifier assigned to each E. coli isolate with MALDI-TOF confirmation.
