Changes in antimicrobial resistance of clinical isolates of Proteus, Morganella, and Providencia species from regional hospitals in Zhejiang Province, 2020 ~ 2024

Background

Proteus, Morganella, and Providencia species are important opportunistic pathogens associated with healthcare- and community-acquired infections, but their recent epidemiological and antimicrobial resistance trends in regional secondary hospitals remain insufficiently characterized. This study investigated the distribution and antimicrobial resistance patterns of these three genera collected from 34 regional medical institutions in Zhejiang Province, China, between 2020 and 2024.
