الملخص EN

Thirty clinical isolates of gram negative bacilli isolated from diarrhea cases in children aged ≤ 5 years were investigated for the presence of β-lactamases, and it was found that 21 (70 %) of them contain these enzymes.

Fifteen positive isolates were selected for the detection of extended spectrum β-lactamases (ESBLs) and AmpC β-lactamases.

The results showed that eight (53.3 %) of the tested isolates were ESBLs producers, and nine (60 %) of them were potential producers of AmpC β-lactamases.

The enzymes were found more frequently in Pseudomonas aeruginosa isolates, followed by Klebsiella pneumoniae and Escherichia coli isolates.
