Molecular Characterization and Extended Spectrum Betalactamase Detection in E. coli and K. pneumoniae Strains Isolates from Intensive Care Units in a Teaching Hospital
Extended Spectrum Betalactamases production from E. coli and K. pneumoniae strains, is a serious public health problem since cause loss of therapeutic effectiveness of betalactams antibiotics. In this research the presence of extended spectrum betalactamases was investigated in E. coli and K. pneumo...
