In fish and aquaculture water, Escherichia coli acts as a key reservoir and vector for AMR, facilitating the dissemination of strains resistant to critically important antibiotics like carbapenems and colistin, often through the production of enzymes such as extended-spectrum ß-lactamases (ESBLs). This review aimed to synthesize recent findings on AMR patterns and associated genes in E. coli from fish and aquaculture waters globally. Studies indicate a high prevalence of resistant E. coli, with MDR to β-lactams, tetracyclines, quinolones, and sulfonamides. Common resistance genes identified include blaTEM, blaCTX-M, tet(A), sul1, and qnrS. The presence of bacterial strains harboring these resistance genes poses a significant public health risk through transmission in the food chain and the environment.

While artemisinin resistance has not yet been observed in the region, molecular surveillance in sub-Saharan Africa has identified Plasmodium falciparum k13 mutations known to confer resistance, making it vitally important to take proactive and creative measures to protect current treatment regimens. Glutathione S-transferases (GSTs), the multifunctional enzymes involved in detoxification and redox control, have emerged as key contributors to drug resistance in Plasmodium species. The role of GSTs in the development of resistance is discussed in the review, and GSTs are presented as prospective molecular targets for the development of novel therapeutic interventions. We examine the complexity of antimalarial resistance in Southern Africa and highlight the potential of GST inhibition as an adjunct therapy to current malaria control measures.

Metagenomic DNA was extracted, and functional genes associated with hydrocarbon degradation (PAH Ring-hydroxylating dioxygenase (PAH-RHDα) and 6-oxocyclohex-1-ene-1-carbonyl-CoA hydrolase (bamA)) were analysed using qPCR.

One set of samples had kerosene concentrations between 154-478.64 µg/g of soil, while the other contained < 11 µg/g. Functional genes analysis linked higher kerosene concentrations to increased gram-negative dioxygenase levels and lower kerosene concentrations to gram-positive dioxygenases.

Pseudomonas aeruginosa, a highly adaptable bacterium, has developed resistance to heavy metals (HMs), which is closely linked to antibiotic resistance through shared genetic and regulatory pathways. This co-resistance poses significant challenges for environmental health and antimicrobial management. Additionally, microplastics act as carriers for HMs and antibiotics, creating a compounded pollution stressor that further influences bacterial resistance patterns. This review explores the molecular mechanisms by which P. aeruginosa resists heavy metal toxicity, focusing on key adaptive strategies such as efflux systems, biofilm formation, enzymatic detoxification, and genetic modifications. These mechanisms enhance bacterial survival in contaminated environments, allowing P. aeruginosa to persist and contribute to the spread of resistance genes. The interplay between HMs, antibiotics, and microplastics underscores the complexity of pollution-driven bacterial adaptation. Addressing these issues requires a multidisciplinary approach that integrates environmental pollution control and antimicrobial resistance management. Understanding how P. aeruginosa thrives under such stress conditions is crucial for developing effective strategies to mitigate the risks associated with heavy metal contamination, antibiotic resistance, and microplastic pollution in both natural and clinical ecosystems.</p>","PeriodicalId":17962,"journal":{"name":"Letters in Applied Microbiology","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144618713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review looks at how an immature immune system and an imbalanced gut microbiome increase the risk of C. difficile infection (CDI) in early life. To reduce this risk, researchers are exploring postbiotics-non-living bacterial products or byproducts-as a safer alternative to traditional treatments like antibiotics. Postbiotics can help by strengthening the gut barrier, reducing inflammation, and supporting the growth of beneficial bacteria. They are also considered safe for use in vulnerable populations, including infants. This review discusses the types of postbiotics, their functions, and how they may help prevent or manage CDI.
