Title: qnr prevalence in ceftazidime-resistant Enterobacteriaceae isolates from the United States. | Journal: Antimicrobial agents and chemotherapy. 2006 Aug;50(8):2872-4 | Authors: Robicsek A, Strahilevitz J, Sahm DF, Jacoby GA, Hooper DC. | Abstract: We screened 313 ceftazidime-resistant Enterobacteriaceae isolates obtained in the United States from 1999 to 2004 for all three known qnr genes. A qnr gene was present in 20% of Klebsiella pneumoniae isolates, 31% of Enterobacter sp. isolates, and 4% of Escherichia coli isolates. qnrA and qnrB occurred with equivalent frequencies and, except for qnrB in enterobacters, were stable over time. qnrS was absent. | See full PubMed entry: http://www.ncbi.nlm.nih.gov/pubmed/16870791 |
