  1. Values reported as frequency (proportion) of E. coli isolates detected carrying the relevant resistance genes. Note that more than one isolate was cultured from some participants and that four isolates from mothers and two isolates from infants were omitted due to poor DNA quality. See Additional File 1: Table S4 for specific genes
