[Predominance and evolution of BLA(SHV) genes in Tunisian hospital isolates of Klebsiella pneumoniae].
Extended-spectrum beta-lactamases (ESBLs)produced by clinical strains of Klebsiella pneumoniae were investigated, using isoelectric-focusing and DNA amplification followed by sequencing. A predominance of SHV variants was found. Sequencing identified the genes for the SHV-2a and -12 enzymes, suggesting direct evolution of SHV-12 from SHV-2a.
