Epidemiological characteristics and antimicrobial resistance of pathogens isolated from blood cultures in southern Jiangxi, China, 2020–2024

In a tertiary hospital in southern Jiangxi, China, Gram-negative bacteria predominate among Patients with positive blood cultures, with sharply rising detection rates of <i>CRKP</i>, <i>CRAB</i>, and <i>VREfm</i> posing a public health threat. Meanwhile, the declining prevalence of <i>MRSA</i> indicates that infection control measures are effective against Gram-positive bacteria. Therefore, continuous surveillance of drug-resistant bacteria is essential, and antimicrobial stewardship measures must be implemented immediately to curb their spread. A limitation of this study is that it was conducted at a single center, which may restrict the generalizability of the findings to other regions.
