is one of the leading causes of healthcare-associated infections and poses challenges in its treatment owing to its high antibiotic resistance. The development of resistance to colistin, which is used as a last resort, has become a major public health problem worldwide. This study was planned according to the PRISMA guidelines and included studies reporting the prevalence of colistin-resistant in Turkey between 2004 and 2024 through a systematic literature review. A total of 28 original research articles were included in the meta-analysis. Data were analyzed using the SPSS and CMA software. The pooled colistin resistance of a total of 8916 strains from 28 studies included in this meta-analysis was found to be 1.63% (95% CI: 1.51-3.12). Colistin resistance increased significantly over time. A higher resistance rate was detected in the strains tested using the EUCAST guidelines and broth microdilution method. The year of the study and validation methods contributed to the heterogeneity observed in the studies. This meta-analysis reveals that colistin-resistant strains have increased over time in Turkey. Current data show that colistin resistance is not only a laboratory finding but has become a crisis, requiring urgent action in terms of hospital infection management and patient safety. Regional and global measures should be taken to ensure the appropriate use of antibiotics to control the development of resistance.

Aims: This study aims to investigate the genomic profile of a multidrug-resistant Escherichia coli strain, 160-11H1, co-carrying an extended-spectrum β-lactamase (ESBL) and the plasmid-mediated mobile colistin resistance gene, mcr-5.
Methods And Results: The entire genome of the strain was sequenced using Illumina MiSeq and Oxford Nanopore platforms, and de novo assembly was performed using Unicycler. The genome size was 5 031,330 bp and comprised 5 140 coding sequences.

In recent years, reports of hypervirulent (hv) carbapenem-resistant (CR) (Kp) (hv-CRKp) have gradually increased. hv-CRKp may emerge from hvKp acquiring mobile genetic elements carrying multiple antibiotic-resistance genes or multi-drug-resistant Kp acquiring virulence genes, with subsequent convergence of resistance and virulence. Thus, hv-CRKp simultaneously harbors resistance and virulence genes and may even show resistance to colistin and tigecycline, suggesting potential for causing severe infections and placing a serious burden on the health care system.

Rapid, low-cost, and visual nucleic acid detection methods are highly attractive for curbing colistin resistance spread through the food chain. CRISPR/Cas12a combined with recombinase-aided amplification (RAA) offers a one-pot, aerosol-free approach for visual detection. However, traditional one-pot systems often run Cas12a trans-cleavage in a buffer suitable for RAA, thus limiting Cas12a cleavage efficiency.

Background And Objectives: Copper is an essential micronutrient and a widely used antimicrobial, yet its widespread application may accelerate microbial resistance. We investigated how long-term copper (II) sulfate (CuSO₄) exposure drives genetic and phenotypic changes in , focusing on survival, resistance mechanisms, and antibiotic cross-resistance.
Methodology: Fifty populations were evolved for 55 days under progressively increasing CuSO₄ concentrations.

Aims: The increasing antimicrobial resistance, particularly in Acinetobacter baumannii, complicates the treatment of infections, leading to higher morbidity, mortality, and economic costs. Herein, we aimed to determine the in vitro antimicrobial, synergistic, and antibiofilm activities of colistin (COL), meropenem, and ciprofloxacin antibiotics, and curcumin, punicalagin, geraniol (GER), and linalool (LIN) plant-active ingredients alone and in combination against 31 multidrug-resistant (MDR) A. baumannii clinical isolates.
