Characterization of blaCTX-M-14 transposition from plasmid to chromosome in Escherichia coli experimental strain
International Journal of Medical Microbiology
Mostly, blaCTX-M is found on transferable plasmids as a component of the blaCTX-M transposition unit containing an insertion sequence, ISEcp1, which exists on the upstream region of blaCTX-Ms. Several recent studies conducted in clinical and community settings have reported the presence of chromosomally located blaCTX-M in extended spectrum β-lactamase (ESBL)-producing bacterial isolates. In this study, we observed the frequency and molecular nature of the ISEcp1-mediated transposition ofdoi:10.1016/j.ijmm.2020.151395 pmid:31959579 fatcat:urs7auycfrcitls7thybmxvnvm
