Prevalence, trends, and molecular insights into colistin resistance among gram-negative bacteria in Egypt: a systematic review and meta-analysis

Annals of Clinical Microbiology and Antimicrobials
Background This study examines colistin resistance in Gram-negative bacteria in Egypt, analyzing prevalence, trends, geographic variations, colistin-carbapenem resistance correlation, and mcr-mediated plasmid resistance. Methods We conducted a systematic

Outer membrane permeability of mcr-positive bacteria reveals potent synergy of colistin and macromolecular antibiotics against colistin-resistant Acinetobacter baumannii

Frontiers in Microbiology
Colistin (CT) is the last-resort of antibiotic against multidrug-resistance (MDR) Acinetobacter baumannii (A. baumannii) infection. However, colistin resistance is increasingly reported in A.

Biofilm‐Mediated Persistence of Salmonella in Poultry Processing: A Comprehensive Review of Isolate Heterogeneity, Stress Adaptation, and Antimicrobial Resistance

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Salmonella enterica remains a major foodborne pathogen in poultry‐processing environments, where its persistence is largely attributed to biofilm formation on food‐contact and non‐food‐contact surfaces. Despite extensive research on Salmonella control, persistent contamination continues to challenge food safety due to the complex interplay ...

Phage-mediated colistin resistance in Acinetobacter baumannii

Aims: Antimicrobial resistance is a global threat to human health, and Acinetobacter baumannii is a paradigmatic example of how rapidly bacteria become resistant to clinically relevant antimicrobials. The emergence of multidrug-resistant A.

Comprehensive insights into colistin and colistin resistance: updated regulations and policies on colistin usage and alternative strategies for mitigation and prevention of colistin resistance

Novel Research in Microbiology Journal
The increase in antimicrobial resistance (AMR) has a significant impact on healthcare, leading to longer hospital stays and higher economic costs. This is primarily caused by the over and inappropriate use of antibiotics. Microorganisms have developed various mechanisms to combat the effects of antibiotics, including modifying their genetic material to

Prevalence of colistin-resistant Enterobacteriaceae isolated from clinical samples in Africa: a systematic review and meta-analysis

BMC Infectious Diseases
Background Antimicrobial resistance among Enterobacteriaceae poses a significant global threat, particularly in developing countries. Colistin, a critical last-resort treatment for infections caused by carbapenem-resistant and multidrug-resistant strains,

MgrB variants in colistin-susceptible and colistin-resistant Klebsiella pneumoniae ST258

Journal of Microbiology, Immunology and Infection, 2017
Resistance determinants of a colistin susceptible and five colistin resistant Klebsiella pneumoniae ST258 from a Hungarian outbreak were investigated. A novel MgrB variant in colistin susceptible strain was found. Elevated phoP and arn gene expressions and wild-type PmrB in all colistin resistant K. pneumoniae were detected. All strains lacked mcr-1.
