Impact of the beta-lacta test on the management of urinary tract infections at the emergency department.

Introduction: Rapid detection of extended-spectrum β-lactamases is essential. In this study, we evaluated the potential impact of β-lacta test on both the times to appropriate antibiotic therapy and to the implementation of patient isolation measures.

Patients And Methods: We included prospectively all the patients admitted to the emergency department for clinical suspicion of urinary tract infection.

Optimization of the β LACTA test for the detection of extended-spectrum-β-lactamase-producing bacteria directly in urine samples.

The β LACTA™ test (BLT) is a chromogenic test detecting resistance to third-generation cephalosporins on bacterial colonies. Some studies have shown that this test can be used directly in urine samples. The aim of this study was to determine the optimal conditions of use of this test in order to detect the ESBL-producing bacteria directly in urine samples.
