Molecular epidemiology of orf513-bearing class 1 integrons in multiresistant clinical isolates from Argentinean hospitals.
The spread of orf513-bearing class 1 integrons is associated with bla(CTX-M-2) in gram-negative clinical isolates in Argentina, with In35 being the most frequently found integron (74%). Among 65 isolates without bla(CTX-M-2), only one harbored a novel orf513-bearing class 1 integron with the dfrA3b gene. The finding of orf513 not associated with class 1 integrons in two gram-positive strains in...
متن کاملCommon regions e.g. orf513 and antibiotic resistance: IS91-like elements evolving complex class 1 integrons.
The ability of bacteria to procure, sometimes rearrange, and evince acquired DNA continues to impress us-even more so if this genetic plasticity involves the sequestering of antibiotic resistance genes. The acquisition of genes in bacteria is often facilitated by transposons, integrons and archetype insertion elements. Recently however, a new element, 'orf513', has been increasingly associated ...
متن کاملAntimicrobial Resistance, Class 1 Integrons, and Genomic Island 1 in Salmonella Isolates from Vietnam
BACKGROUND The objective was to investigate the phenotypic and genotypic resistance and the horizontal transfer of resistance determinants from Salmonella isolates from humans and animals in Vietnam. METHODOLOGY/PRINCIPAL FINDINGS The susceptibility of 297 epidemiologically unrelated non-typhoid Salmonella isolates was investigated by disk diffusion assay. The isolates were screened for the p...
متن کاملMolecular diversity of class 1 integrons in human isolates of Aeromonas spp. from southern Taiwan.
This work studies antimicrobial resistance and class 1 integrons of Aeromonas spp. in human isolates from southern Taiwan. PCR amplification and DNA sequence analyses were performed to characterize the gene cassette regions of the class 1 integron in 204 isolates of Aeromonas hydrophila, 36 isolates of A. sobria, 23 isolates of A. veronii, and 4 isolates of A. caviae. By using Southern hybridiz...
متن کاملEpidemiological Characterizations of Class 1 Integrons from Multidrug-Resistant Acinetobacter Isolates in Daejeon, Korea
BACKGROUND Multidrug-resistant (MDR) Acinetobacter spp. acquire antimicrobial agent-resistance genes via class 1 integrons. In this study, integrons were characterized to investigate the antimicrobial resistance mechanisms of MDR Acinetobacter isolates. In addition, the relationship between the integron type and integron-harboring bacterial species was analyzed by using epidemiological typing m...
