Bacteria harboring the aac(6′)-Ib gene predominated in raw sewage. qnrS-positive bacteria were specific to activated sludge. First report of the qnrS gene in Providencia rettgeri and Pseudomonas guangdongensis. aac(6′)-Ib-cr: first report in Alcaligenes faecalis and Providencia rettgeri. QnrS and AAC(6′)Ib exhibited many amino acids alterations previously undetected.
