Molecular detection of carbapenemases in critical microorganisms since the onset of the COVID-19 pandemic in Peru.

ABSTRACT:

Objective

Identify and characterize carbapenemase genes in bacterial isolates of Enterobacterales, Acinetobacter baumannii, and Pseudomonas aeruginosa collected through the National Surveillance of Antimicrobial Resistance (AMR) Program during the COVID-19 pandemic in Peru.

Methods

This retrospective, observational study analysed 2049 submitted due to suspected portability of carbapenemase genes, collected between January 2020 and August 2022. Samples were obtained from 61 hospitals in 18 of the 25 regions of Peru (72%) that participated in the National Surveillance AMR Program.

Results

Among the isolates, 860 were Enterobacterales, 771 were A. baumannii, and 418 were P. aeruginosa. Carbapenemase genes were detected in 1735 isolates (84,6%)
