Resumen

The characterization of extended-spectrum beta-lactamases, plasmidic AmpC (pAmpC), and associated plasmid-mediated quinolone resistance (PMQR) determinants in cefotaxime-resistant coliforms isolated from hospital effluent in Algiers showed bla CTX-M genes in 89%, bla TEM-1 in 79•8%, and pAmpC genes (bla CIT) in 2•7% isolates. Association of IS Ecp1B with bla CTX-M was found in all CTX-M+ isolates, and 97•2% harboured class 1 integrons. Sequencing showed bla CTX-M-15, bla CTX-M-3, and bla CMY-4 genes. bla CTX-M-3 and bla CTX-M-15 were located in Inc L/M conjugative plasmids. The PMQR determinants identified were qnrB1, qnrB2, qnrB9, qnrB19, qnrS2, and aac(6')-Ib-cr. qnrB2, qnrB9, qnrB19, and bla CMY-4are described for the first time in Algeria and qnrB19 for the first time in non-clinical environments. This study highlights the major potential role of hospital effluents as providers of resistance genes to natural environments. © 2014 Edizioni Scientifiche per l'Informazione su Farmaci e Terapia.
