Summary: Many antibiotic-resistant bacteria can transfer resistance genes on plasmids to other bacteria. In this study, we found that the broad-host-range plasmid RP4 can transfer between different enteric bacteria, including clinically relevant species. The transfer frequencies varied among different donor-recipient pairings, and the plasmid also showed the ability to retransfer back to its original host. However, the persistence of the plasmid decreased over time without the presence of antibiotics. These findings highlight the potential for plasmid-mediated spread of antibiotic resistance among bacterial populations.

Summary: Conjugative plasmids can be transferred horizontally in bacteria, contributing to the transmission of antibiotic resistance genes. This study reveals that the hormone estradiol can promote the transfer of plasmids in Enterococcus faecalis, increasing antibiotic resistance. It is suggested that estradiol activates the pheromone signaling cascade and directly binds to the pheromone receptor, enhancing plasmid transfer and antibiotic resistance.

Summary: The enrichment and spread of antibiotic resistance genes (ARGs) induced by environmental chemical pollution pose a threat to human health and ecological safety. This study established a new conjugation model and confirmed that environmentally relevant concentrations of bisphenols (BPs) can significantly promote the conjugation of ARGs mediated by plasmid pCF10. The findings provide new insight into the environmental behavior and biological effect of BPs and offer a new method and theory for studying the enrichment and spread of ARGs induced by environmental chemical pollution.

Summary: Chemical pollution in the environment enhances the spread of antibiotic resistance genes (ARGs), posing a threat to human health and ecological safety. Bisphenols (BPs) have been found to significantly promote the conjugation of ARGs mediated by plasmids in bacteria. Bisphenol A (BPA) upregulates pheromone expression, promotes bacterial aggregation, and even directly activates conjugation.

Summary: Antibiotic resistance is propagating worldwide, with an increasing abundance of antibiotic resistance genes (ARGs) in conjugative plasmids being a key factor in the propagation of resistance. The abundance of ARGs in plasmids has increased by 10-fold on a global scale from 2000 to 2020, especially in low-to-middle income countries. If antibiotic consumption continues to grow at current rates, there may be a 2.7-fold increase in the global abundance of clinically relevant plasmid-borne ARGs by 2030. High sequence similarities of clinically relevant plasmids isolated from clinics and the environment raise concerns about the environmental resistome serving as a reservoir for ARG transmission.

Summary: This study investigated the effects of biochar on the conjugative transfer of antibiotic resistance genes (ARGs). It was found that biochar pyrolyzed at higher temperatures had a stronger inhibitory effect on the transfer of ARGs. This inhibition was primarily caused by down-regulation of plasmid transfer gene expression and decreased cell membrane permeability due to restricted ATP energy supply. On the other hand, coating biochar with fulvic acid weakened this inhibitory effect by providing more ATP and enhancing intracellular reactive oxygen species defense.

Summary: The study found that dissolved biochar can promote the transfer of antibiotic resistance genes in bacteria, with humic acid-like substances playing an important role. However, increasing the concentration of dissolved biochar weakens this transfer effect, leading to a decrease in the frequency of antibiotic resistance gene transfer.

Summary: The simultaneous exposure to Cd2+ and high concentration nano Fe2O3 significantly increased the transfer frequencies of plasmid RP4, leading to the formation of more transconjugants, most of which were identified as human pathogens. The co-effect of Cd2+ and nano Fe2O3 enhanced cell membrane permeability, antioxidant enzyme activities, and mRNA expression levels of conjugation genes, exacerbating the conjunctive transfer of ARGs.

Summary: The prevalence and spread of multidrug-resistant bacteria is a global challenge to public health. This study assessed the effect of certain disinfectants on bacterial transformation and found that these disinfectants significantly enhanced the transformation of plasmid-encoded antibiotic resistance genes. The study also revealed the mechanisms underlying the promotive effect of disinfectants on transformation. These findings provide new insights into the spread of antibiotic resistance genes through bacterial transformation and indicate potential risks associated with the widespread use of disinfectants.

Summary: In this study, the influence of polystyrene micro/nanoplastics (MNPs) on gene transfer was investigated. It was found that the effect of MNPs on gene transfer was dependent on their size, with small MNPs causing a fluctuation in gene transfer efficiency, moderate-sized MNPs increasing gene transfer efficiency, and large MNPs having minimal impact. Furthermore, the gene transfer efficiency could be further enhanced by optimizing mating time and ratio.

Summary: Current in the milliampere range can enhance conjugal plasmid transfer between bacteria, including antibiotic-resistant bacteria. The exposure to sublethal current intensities during electrochemical disinfection can lead to increased transconjugant frequency and expression of conjugation-related genes. It is crucial to carefully control the conditions of electrochemical disinfection to prevent the transmission of antibiotic resistance genes.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
