Key Findings

The study identified various beta-lactamases, including TEM-type, CMY-2, and OXA-type, in amoxicillin-clavulanate-resistant Escherichia coli isolates. Notably, two isolates harbored inhibitor-resistant TEM enzymes (TEM-34 and TEM-122) that conferred resistance to amoxicillin-clavulanate.
