Nettet5. feb. 2016 · Our results highlight the need for experimental studies of integron population biology. Integrons are genetic elements that are common in bacteria and are hotspots for genome evolution. Nettet21. okt. 2024 · Results . Among the analyzed strains, Serratia marcescens was a predominant species (103/112, 92.0%). All three classes of integrase DNA sequence were detected in the analyzed strains of Serratia spp. DNA sequence of class 3 integron, besides integrase gene, revealed three gene cassettes (dfrB3, bla GES-7,bla …

Nettet7. feb. 2024 · Integrons are bacterial genetic elements notorious for their role in spreading antibiotic resistance in clinical settings. In the natural environment, integrons present a wide and hidden diversity, raising questions as to their broader role in bacterial adaptation. NettetIntegron analysis indicated the preponderance of class 2 and atypical class 1 integrons in that population. Typical class 1 integron was present in only one S. sonnei isolate and harbored trimethoprim resistance-encoding gene dfrV, while atypical class 1 integrons harbored dfrA1–aadA or blaOXA-aadA gene cassettes responsible for resistance to … elements in group 17 are known as
