Introduction: Bacterial resistance is a major threat to public health worldwide. To gain an understanding of the clinical infection distribution, drug resistance information, and genotype of CRE in Dongguan, China, as well as the resistance of relevant genotypes to CAZ-AVI, this research aims to improve drug resistance monitoring information in Dongguan and provide a reliable basis for the clinical control and treatment of CRE infection.

Methods: VITEK-2 Compact automatic analyzer was utilized to identify 516 strains of CRE collected from January 2017 to June 2023.

is a globally prevalent foodborne bacterium, and ceftriaxone and azithromycin have been regarded as drugs of choice for treating infections, particularly in children. With the growing incidence of ceftriaxone and azithromycin resistance in , there is an urgent requirement for a rapid and dependable gene testing approach to enhance the efficacy of treating infections. Utilizing the orange to green visible dye approach, this study developed loop-mediated isothermal amplification (LAMP) assays for the sensitive and specific detection of , ceftriaxone and azithromycin resistance genes (including CTX-M-1 group, , and genes) in stool and blood samples.

The emergence of tigecycline-resistant tet(X2/X3/X4/X5) genes poses a new threat to the efficacy of anti-infective therapy and the safety of our food and environment. To control the transfer of such genes, a sensitive and rapid molecular method is warranted to detect tet(X2/X3/X4/X5) genes in clinical isolates. Herein, we established a loop-mediated isothermal amplification (LAMP) assay to rapidly detect tet(X2/X3/X4/X5) genes, and the results were assessed by chromogenic visualization.
