چکیده

Genetic and functional characterization of the cephalosporinases produced by 65 clonally unrelated clinical Escherichia coli isolates revealed genetic diversity of the ampC genes and showed that Gln287, Cys287, Pro296, Leu298, and Phe350 substitutions were involved in extension of the hydrolysis spectrum to include ceftazidime and cefepime.

The multidrug resistance and production of extended-spectrum beta-lactamases ctx-m, per and ver in Escherichia coli isolates derived from raw dairy samples

The occurrence of extended-spectrum beta-lactamases-producing bacteria is an important public health issue. The aim of this study was to investigate phenotypic and genotypic characteristics regarding the presence of extended spectrum β-lactamase ctx-m, per and ver producing Escherichia coli isolated from raw dairy samples. For this purpose, E. coli were isolated from 247 raw dairy samples (milk...
