Characterization of a novel qepA3 variant in Enterobacter aerogenes

Abstract Five isolates harboring qepA were studied by polymerase chain reaction (PCR) amplification and relevant methods. One was determined to be a novel qepA3 from Enterobacter aerogenes , and four involved three qepA1 and one qepA2 determinants from Escherichia coli ; the qepA3 changed five amino...

Description
Summary:Abstract Five isolates harboring qepA were studied by polymerase chain reaction (PCR) amplification and relevant methods. One was determined to be a novel qepA3 from Enterobacter aerogenes , and four involved three qepA1 and one qepA2 determinants from Escherichia coli ; the qepA3 changed five amino acids. These results characterized genetic structures A, B, C, D, and E.
