A remarkable prevalence ofqnrB (54%) and, at a lower level, ofqnrS (14%) was discovered in pools of commensal enterobacteria from 310 healthy children living in Peru and Bolivia, using a metagenomic approach. Analysis of randomly selected enterobacterial pools revealed thatqnrB was mainly carried byEscherichia coli andqnrS byKlebsiella pneumoniae . Investigation of 11qnrB -positive isolates and 9qnrS -positive isolates revealed the presence of plasmid-borneqnrB19 (n = 8),qnrB2 (n = 2),qnrB10 (n = 1), andqnrS1 (n = 9) genes.
