ABSTRACT
OBJECTIVE:
To determine the sequence of gene for encoding beta-lactamase produced by Klebsiella pneumoniae E3 isolated from Jiaxing Area in Zhejiang Province. METHODS The Klebsiella pneumoniae strain E3 was identified as an ESBLs-producing bacterium by inhibitor-potentiated broth dilution test. The gene encoding gamma-lactamase of the strain was amplified by PCR. The purified PCR product was cloned and sequenced by Sanger's dideoxy chain termination composition method. RESULTS The Klebsiella pneumoniae strain E3 produced both TEM and SHV gamma lactamases. The SHV encoding gene had 812 nucleotide residues responsible for encoding SHV-11 gamma-lactamase and the TEM encoding gene had 973 nucleotide residues responsible for encoding TEM-1 gamma-lactamase. CONCLUSION The Klebsiella pneumoniae strain E3 isolated from a patient in Jiaxing Area in Zhejiang Province is able to produce both TEM-1 and SHV-11 gamma-lactamases.
