Letter to the Editor: Four Novel Types of Gene Cassettes from Carbapenem-Resistant Pseudomonas aeruginosa in Southern China—First Report of qnrVC7.

For array 5'CS I accA4-bla SB IMP45 sb i -3'CS, a 1,400 bp fragment was lost after the ORF of I bla SB IMP45 sb i . As concluded, a total of four novel arrays in class 1 integrons were identified in this study, including 5'CS I accA4-bla SB IMP45 sb -oxa1-catB i 3-3'CS, 5'CS I accA4-bla SB IMP45 sb i -3'CS, 5'CS I accA4-bla SB IMP45 sb -oxa1-catB i 3-3'CS, and 5'CS I accA4-bla SB IMP45 sb i -3'CS, from which I qnrVC7 i had been first reported in I P. aeruginosa i and I bla SB IMP45 sb i had also been identified for the third time. In addition, I bla SB IMP45 sb i was detected in two novel arrays of cassettes in class 1 integrons, including 5'CS I accA4-bla SB IMP45 sb -oxa1-catB i 3-3'CS and 5'CS I accA4-bla SB IMP45 sb i -3'CS.
