ABSTRACT<br /> 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.
