Article Abstract
The emergence of genetic mutations in chromosomal genes and the transmissible plasmid-mediated colistin resistance gene may have helped in the spread of colistin resistance among various Klebsiella pneumoniae (K. pneumoniae) isolates and other different bacteria. In this study, the prevalence of mutated colistin-resistant K. pneumoniae isolates was studied globally using a systematic review and meta-analysis approach. A systematic search was conducted in databases including PubMed, ScienceDirect, Scopus and Google Scholar. The pooled prevalence of mutated colistin resistance in K. pneumoniae isolates was analyzed using Comprehensive Meta-Analysis Software (CMA). A total of 50 articles were included in this study. The pooled prevalence of mutated colistin resistance in K. pneumoniae was estimated at 75.4% (95% CI = 67.2−82.1) at high heterogeneity (I2 = 81.742%, p-value < 0.001). Meanwhile, the results of the subgroup analysis demonstrated the highest prevalence in Saudi Arabia with 97.9% (95% CI = 74.1−99.9%) and Egypt, with 4.5% (95% CI = 0.6−26.1%), had the lowest. The majority of mutations could be observed in the mgrB gene (88%), pmrB gene (54%) and phoQ gene (44%). The current study showed a high prevalence of the mutation of colistin resistance genes in K. pneumoniae. Therefore, it is recommended that regular monitoring be performed to control the spread of colistin 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.
