Antimicrobial Resistance of Serratia marcescens Recovered From Aquatic Environments: A Review

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Serratia marcescens is a gram‐negative bacillus forming biofilms and showing multidrug resistance. Review (2019–2024) included 13 studies, 90 aquatic isolates. High resistance to β‐lactams, including carbapenems. Genes: blaOXA‐48, blaTEM‐1, aac(6′)‐Ic. Aquatic environments are reservoirs, requiring monitoring and control to prevent spread.

Molecular mechanisms and genetic epidemiology of colistin resistance in Pseudomonas aeruginosa: a systematic review and meta-analysis

Discover Bacteria
Colistin is a last-resort antibiotic for multidrug-resistant (MDR) and extensively drug-resistant (XDR) P. aeruginosa infections; however, colistin-resistance is rising globally.

Fungicide Drives De Novo Evolution of Multidrug Resistance in the Plant Growth Promoting Rhizobacterium, Pseudomonas fluorescens

Evolutionary Applications, Volume 19, Issue 8, August 2026.
ABSTRACT Soil microbial communities underpin key ecosystem processes, including plant health, nutrient cycling and primary productivity. In agricultural soils, beneficial soil bacteria are often exposed to multiple stressors simultaneously, including fungicides, antibiotics, and warming temperatures. Despite their ecological importance, little is known
