| stenotrophomonas maltophilia resistance to trimethoprim/sulfamethoxazole mediated by acquisition of sul and dfra genes in a plasmid-mediated class 1 integron. | stenotrophomonas maltophilia is becoming a more and more common cause of infections. in this study, the minimal inhibitory concentrations of trimethoprim/sulfamethoxazole (sxt), ceftazidime, minocycline, levofloxacin, chloramphenicol and ticarcillin/clavulanic acid were determined and the distribution of integrons and sul1, sul2 and dfra genes was investigated in 102 s. maltophilia isolates collected from patients treated in 31 hospitals in anhui, china, in the month of september in 2006-2008. t ... | 2011 | 21296557 |
