Summary: Research on antibiotic resistance genes (ARGs) in Mariana Trench sediments shows a sudden increase in abundance and diversity, with 63.6% of the ARG pollution predicted to have anthropogenic sources. This indicates that human activities have already permeated into the deepest ocean regions, emphasizing the need for better pollution control measures to prevent the accumulation and potential threat of ARG dissemination.

Summary: This study identifies landfill leachate as an important source of antibiotic resistance genes (ARGs) that can penetrate and spread into nearby groundwater. Heavy metals, bacterial community, and mobile genetic elements (MGEs) were found to be the driving factors shaping the patterns of ARGs in water samples, explaining 57% of their variations.

Summary: A metagenomics-based technological framework was proposed to evaluate the potential and utility of FEAST as an ARG profile-based source apportionment tool. The performance of FEAST was checked using a large panel of metagenomic data sets and confirmed its suitability to discriminate samples from different source types. The validated FEAST was applied to track the sources of ARGs in river sediments, showing the main contributors of ARGs were STP effluents, followed by sludge and aquaculture effluent.

Summary: Research has shown that bioplastics accumulate antibiotic and metal resistance genes in marine sediments, with the PHA group being particularly enriched in certain ARGs and MRGs. There is a strong correlation between the relative abundance of ARGs and MRGs, and PHA biofilms were found to be colonized by antibiotic-resistant hemolytic Bacillus cereus group bacteria.

Summary: Antibiotic resistance poses a serious threat to humanity and its environment, and the misuse of antibiotics in human, animal, and environmental sectors contributes to its spread. Antibiotics are used to treat infections in humans and promote growth in food-producing animals, leading to the transmission of antibiotic resistant infections from animals to humans. Antibiotics can enter the environment through various sources, including human and veterinary wastes. The soil serves as a reservoir of antibiotic resistance genes, and there are concerns about the potential health hazards of environmental antibiotic residues. The One Health approach aims to address antibiotic resistance in an interconnected and multi-sectoral manner, by implementing surveillance, overcoming resource challenges, and executing action plans at national and international levels. Implementing One Health can help prevent the emergence and dissemination of antibiotic resistance and promote a healthier world.

Summary: In recent years, the excessive use of antibiotics in livestock and poultry husbandry has led to the accumulation of residual antibiotics and antibiotic resistance genes (ARGs) in livestock manure. Composting can effectively reduce the risk of ARGs in manure. This study found that the potential risk of ARGs in compost was significantly lower than in manure, suggesting that composting is an effective method for reducing ARGs.

Summary: The study found that metal(loid) selection plays an important role in the dissemination of antibiotic resistance genes (ARGs) in mine soil ecosystems. Metal(loid)-induced coselection is mainly associated with resistance-nodulation-division (RND) antibiotic efflux. Metal(loid)s impose coselection pressure on multiple ARGs residing on mobile genetic elements (MGEs), promoting the dissemination of the antibiotic resistome.

Summary: The distribution of antibiotic resistance genes (ARGs) in brackish water aquaculture sediment is similar to that in freshwater aquaculture, with the sulfonamide resistance gene sul1 as the indicator. The dominant phyla are Proteobacteria and Firmicutes, with Paenisporosarcina as the dominant genus. The microbial community in brackish water aquaculture sediment is function-driven and influenced by environmental factors and aquaculture activities. Overall, brackish water aquaculture serves as a reservoir for ARGs.

Summary: This study reveals that the absolute abundance of ARG subtypes in winter is generally twice as high as in summer, possibly due to winter haze events with high particulate matter concentrations in Handan. Exogenous input from serious haze events and local release of ARGs loaded on PM2.5 of air masses may cause higher levels of ARGs in the winter.

Summary: The abuse or misuse of antibiotics is directly linked to the emergence of antibiotic-resistant bacteria and antibiotic resistance genes in the environment. Fish farm effluents contain higher levels of ARGs than seawater, with ARGs mainly found on plasmids. The microbial community differs between summer and winter, and fish farm samples contain more opportunistic pathogens and virulence factors.

Summary: The study found that swimming pools contain a higher abundance of ARGs, with bather loads contributing to their increase, and dermal contact being identified as the main exposure route for ARGs. Furthermore, the burden of ARGs intake via dermal contact during swimming was higher than that via ingestion.

Summary: This study investigated the presence of antibiotics, antibiotic resistant bacteria (ARB), and antibiotic resistance genes (ARGs) in aquaculture waters, as well as the removal effects of ferrate (Fe(VI), FeO42-). It found that water quality parameters significantly influenced the dissemination of tetracycline resistance genes in aquaculture waters, and the efficiency of antibiotics removal by Fe(VI) depended on the structural moieties of antibiotics. The results suggest that the constituents of farming water enhance the efficacy of antibiotics removal by Fe(VI), and an acidic pH environment can enhance Fe(VI) inactivation of ARB over circumneutral pH.

Summary: Previous studies focused on direct interactions of plastics with microorganisms, but ignored their ecotoxicity effects on the dissemination of antibiotic resistance genes (ARGs). This study reveals that environmentally relevant concentrations of phthalates (PAEs) significantly enhance the transfer of ARGs among environmental microorganisms. The interaction between PAEs and cell membrane phospholipids lowers membrane fluidity and increases permeability, facilitating gene transfer. Increased levels of reactive oxygen species and overexpression of conjugation-associated genes under PAE stress also contribute to enhanced gene transfer. This study provides important insights into the environmental risks of plastics and the control of ARG spreading.

Summary: The quality and environmental effects of the Bacillus probiotic compound BG4 in aquaculture were evaluated. Adding BG4 to aquaculture water system led to significant degradation rates of ammonia nitrogen, phosphate, and chemical oxygen demand. However, there was no significant difference in survival rate and water quality between the BG4 and control groups. Quality evaluations and scientific assessments are necessary for the use of probiotics in commercial aquaculture.
