Characterization of drug resistant Salmonella enterica serotype Typhimurium by antibiograms, plasmids, integrons, resistance genes and PFGE.
Forty-seven Salmonella Typhimurium (33 zoonotic, 14 clinical) strains were tested for antimicrobial resistance using the standard disk diffusion method. Presence of relevant resistance genes and class 1 integrons were investigated by using PCR. Pulsed-field gel electrophoresis (PFGE) and plasmid profiling were carried out to determine the genomic diversity of Salmonella Typhimurium. Approximate...
متن کاملCiprofloxacin-Resistant Salmonella enterica Serotype Typhimurium, China
We characterized 44 Salmonella enterica serotype Typhimurium isolates from Tongji Hospital outpatients in Wuhan, China, May 2002-October 2005. All 31 ciprofloxacin-resistant isolates were also resistant to > or = 8 other antimicrobial drugs and carried > or = 2 mutations in GyrA and 1 mutation in ParC. Class 1 integrons were identified in 37 isolates.
متن کاملCharacterisation of integrons and antibiotic resistance genes in Danish multiresistant Salmonella enterica Typhimurium DT104.
The presence and genetic content of integrons was investigated in eight Salmonella enterica Typhimurium DT104 isolates from different pig herds in Denmark. Two different integrons were identified using PCR and sequencing. Each of the integrons carried a single resistance cassette in addition to the sul1 and qacE delta 1 genes characteristic of integrons. The first integron encoded the ant (3")-...
متن کاملExpanding drug resistance through integron acquisition by IncFI plasmids of Salmonella enterica Typhimurium.
We conducted a 30-year retrospective analysis of IncFI plasmids from Salmonella enterica serotype Typhimurium. These plasmids have been associated with the emergence of epidemic clones of multidrug-resistant Salmonella. Molecular and genetic evidence indicates that IncFI plasmids are evolving through sequential acquisition of integrons carrying different arrays of antibiotic- resistance genes.
متن کاملSpread of oqxAB in Salmonella enterica serotype Typhimurium predominantly by IncHI2 plasmids.
OBJECTIVES To investigate the prevalence and genetic environment of the multiresistance gene oqxAB in Salmonella enterica serotype Typhimurium isolated from food-producing animals. METHODS In this study, 63 Salmonella enterica serotype Typhimurium isolates were analysed for the presence of plasmid-mediated quinolone resistance determinants and mutations in the quinolone resistance-determining...
