Introduction The antimicrobial resistance of is variable and is influenced by both geographic location and regional antibiotic use. The overuse of antibiotics, especially in hospitalised patients, suppresses the growth and persistence of drug-resistant bacteria. This study aimed to detect the prevalence of carbapenem-resistant and the genes responsible for the resistance.

This study aimed to analyze the clinical and molecular characteristics of carbapenem-resistant Enterobacteriaceae (CRE) bloodstream infection (BSI) in patients with hematological diseases and to explore prognostic risk factors. This retrospective study included patients with hematologic diseases with CRE BSI at the Institute of Hematology and Blood Diseases Hospital from January 2015 to December 2022. The clinical features, carbapenemase test results, antimicrobial treatments, and outcomes were analyzed.

Carbapenemase producing (CPEs) represent a group of multidrug resistant pathogens for which few, if any, therapeutics options remain available. CPEs generally harbor plasmids that encode resistance to last resort carbapenems and many other antibiotics. We previously performed a high throughput screen to identify compounds that can disrupt the maintenance and replication of resistance conferring plasmids through use of a synthetic screening plasmid introduced into K-12 cells.

Gastrointestinal carriage of antimicrobial-resistant bacteria, especially carbapenemase-producing Enterobacterales (CPE), presents a critical public health threat globally. However, in many resource-constrained countries, epidemiological data on CPE is limited. Here, we assessed gastrointestinal carriage and associated factors of CPE among inpatient and outpatient children (≤ 5 years).

We identified a novel mechanism contributing to decreased FDC susceptibility in Klebsiella pneumoniae clinical isolates. The mechanism involves 2 coresident plasmids: pKpQIL, carrying variants of bla carbapenemase gene, and pKPN, carrying the ferric citrate transport (FEC) system.
