Combating antimicrobial resistance: the silent war
This review examines the growing global crisis of antimicrobial resistance, where bacteria become immune to antibiotics due to overuse in medicine and agriculture. Although focused on drug resistance, the paper is relevant to microplastic research because microplastics have been shown to harbor antibiotic-resistant bacteria and facilitate the transfer of resistance genes in the environment, potentially making this public health crisis worse.
The Fate and Occurrence of Antibiotic-Resistant Bacteria and Antibiotic Resistance Genes during Advanced Wastewater Treatment and Disinfection: A Review
This review examines how advanced wastewater treatment and disinfection methods perform at removing antibiotic-resistant bacteria and their resistance genes. While methods like UV, ozone, and membrane filtration reduce resistance levels, none fully eliminate them, and some treatments can even promote gene transfer. Since wastewater plants are key nodes where antibiotic resistance spreads to the environment, improving these treatment processes is critical for public health.
Reducing bacterial antibiotic resistance by targeting bacterial metabolic pathways and disrupting RND efflux pump activity
This review examines strategies to overcome antibiotic resistance by targeting bacterial metabolic pathways and disrupting efflux pump systems that expel antibiotics from bacterial cells. The paper is focused on pharmaceutical microbiology rather than microplastic contamination.
The Complex Interplay Between Antibiotic Resistance and Pharmaceutical and Personal Care Products in the Environment
This review explores the complex relationship between antibiotic-resistant bacteria, antibiotic resistance genes, and environmental contaminants including pharmaceuticals and personal care products. Researchers found that antibiotic resistance is often elevated in human-impacted environments, particularly where faecal waste and chemical contaminant mixtures are present. The study highlights how environmental pollution, including microplastic contamination, may contribute to the spread of antibiotic resistance through horizontal gene transfer and bacterial adaptation.
Versatility of Stenotrophomonas maltophilia: Ecological roles of RND efflux pumps
Researchers reviewed the ecological roles of molecular pumps in Stenotrophomonas maltophilia, a widespread environmental bacterium, finding these pumps help the microbe adapt to diverse habitats — not just resist antibiotics as previously assumed. Understanding these pumps' broader functions in soil, water, and plant environments could inform strategies to manage antibiotic resistance and understand how bacteria colonize multiple niches.
