All isolates were negative for mcr−1 to 8 by qPCR and whole genome sequencing. A detailed description of each isolate, including bacterial species, date of sampling, specimen type, its origin, antibiotic resistance mechanisms, TTP obtained by the mcr−9 LAMP, and WGS results can be found in Tables S2 and S3.
