Summary: Tetracycline residues in sediment typically reach their peak on the 5th day before gradually decreasing; while non-therapeutic concentrations of tetracycline seem to have no adverse effects on sediment nitrogen and carbon cycling rates, they may reduce microbial abundance in the short term and promote the proliferation of antibiotic resistance genes in the long term.

Summary: The study revealed significant differences in resistome profiles between termite mounds and bulk soils, with lower abundance and diversity of antibiotic resistance genes (ARGs) in termite mounds compared to bulk soils. The proportion of efflux pump ARGs was also significantly lower in termite mounds. These differences are suggested to be a result of changes in microbial interactions due to the increase in pH and nutrient availability induced by termite nesting activities.

Summary: The infiltration of reclaimed water into riparian groundwater has led to the spread of antibiotic resistance genes (ARGs), posing a significant environmental risk. Reclaimed water from wastewater treatment plants (WWTPs) has been identified as a source of antibiotics and ARGs in groundwater based on their spatial and temporal distribution. The assembly process of microbial communities in the groundwater of the infiltration zone is primarily influenced by deterministic processes. The dominant shared genera in the co-occurrence network analysis, such as Thermotoga, Desulfo-tomaculum, and Methanobacterium, are considered core genera and hosts of ARGs for the transport from reclaimed water to groundwater.

Summary: Comprehensive studies on the effects of cold stress on antibiotic resistance genes (ARGs) in the intestines and feces are lacking. This study found that short-term cold stress can reduce the abundance of ARGs in the cecum and feces of pigs, with factors such as bacterial community composition, metabolites, and mobile genetic elements playing significant roles.

Summary: Nearly 80% of the population in the Colombo district rely on the Kelani river for their major needs, but recent studies have shown contamination of groundwater and surface water with waterborne pathogens and antibiotics. The study identified nine antibiotic resistance genes, with high levels of penicillin and tetracycline resistance genes found in the lower part of the Kelani river basin. Regular monitoring and water quality management are essential to protect the drinking water quality in this area.

Summary: This study develops a bio-informatic pipeline using deep learning techniques to identify phages carrying antibiotic resistance genes (ARGs) and predict their hosts, with a focus on pathogens. The study discovers that temperate phages in a landscape lake replenished by reclaimed water predominantly carry ARGs related to multidrug resistance and beta-lactam antibiotics. In silico analysis and qPCR confirm a positive correlation between temperate phages and host pathogens, and seasonal variations in the abundance of phages and chromosomes carrying ARGs.

Summary: The study investigated the source contribution and correlations between antibiotics and ARGs in surface water of Fuxian Lake. Results showed that SMX and OFL were the dominant antibiotics and their corresponding ARGs posed medium risk to aquatic organisms, mainly originating from anthropogenic sources. The presence of ARGs in the lake was significantly lower than in inflowing rivers, suggesting inconsistent correlations between antibiotics and ARGs in the lake.

Summary: Horizontal gene transfer (HGT) is the most important pathway for the introduction of antibiotic resistance genes (ARGs), which pose serious threats to human health and biological security. This study developed a visual conjugative model to investigate the potential for HGT and the role of exogenous ARGs in the intestinal microbiome. The results showed that ARG transfer could occur more easily under stressors, and the viability of intestinal bacteria played a key role in conjugation efficiency. Furthermore, the study revealed the mechanisms of ARG transfer under stress and identified the predominant recipient species.

Summary: This study assessed the diversity, abundance, and expression of antibiotic resistance genes (ARGs) in a Chinese landfill using high-throughput quantitative PCR. The results showed that the total abundance of ARG transcripts was significantly higher in young refuse compared to old refuse, with heavy metals being the major driver affecting the profile of ARGs. These findings provide new insights into the potential threats posed by ARGs in landfills.

The strain, BTXS2, exhibited unique carbon source utilization and enzyme activity, and was able to grow in various environmental conditions. Multiple antibiotic resistance genes and virulence genes that pose a risk to human health were found in the BTXS2 genome. The phage, VB_VpP_BT-1011, showed antibacterial effects against BTXS2 and was able to tolerate a broad range of environmental conditions.

Summary: This study analyzed the composition and abundance of antibiotic resistance genes (ARGs) in different rivers and riverbank soils in northeast China using metagenomic sequencing. The results showed that multidrug resistance genes were the predominant ARGs in the samples, and the composition of ARGs was similar among the three rivers. ARGs in riverbank soils were also detected in the river water, indicating potential gene transfer. Opportunistic pathogenic bacteria carrying resistance genes were mainly associated with diarrhea and respiratory infections. The findings provide valuable insights into the distribution of ARGs in river water in northeast China.

Summary: Disinfection by-products (DBPs) are unintended consequences of water disinfection that can enhance antimicrobial resistance by stimulating the conjugative transfer of antibiotic resistance genes (ARGs). This study found that two typical DBPs, trichloromethane (TCM) and dichloroacetonitrile (DCAN), significantly stimulated the conjugative transfer of ARGs, with underlying mechanisms involving intracellular reactive oxygen species generation and upregulation of genes and proteins related to pilus generation, ATP synthesis, and RP4 gene expression.
