Summary: This study found that antibiotics from livestock wastewater were absorbed and accumulated by water dropwort, but the health-risk coefficients were below the threshold. Antibiotic resistance genes (ARGs) were closely correlated between livestock wastewater and water dropwort, with tetracycline resistance genes being the most abundant. The intake of ARGs in water dropwort may pose a potential risk, and more research is needed to fully understand the health risks.

Summary: This study analyzes the prevalence of antibiotic resistance genes (ARGs) in various water environments in Thailand using high-throughput qPCR. The study reveals a widespread presence of ARGs in different water types, suggesting a circulation of resistance determinants across the aquatic environment. The study also highlights the higher abundance of ARGs in effluent and river water, indicating possible inadequate wastewater treatment and environmental contamination. Seasonal impacts on wastewater treatment practices and pollution patterns are also observed.

Summary: In this study, the occurrence of multidrug-resistant Enterobacter spp. in different water sources was investigated. The isolates showed resistance mainly to β-lactam antibiotics and harbored β-lactam antibiotic resistance genes, with blaKPC being widely detected. Metal tolerance genes were also found in the isolates. These findings highlight the urgent need for control measures to prevent the spread of antibiotic-resistant Enterobacter spp. and emphasize the waterborne transmission of clinically important antibiotic-resistant bacteria.

Summary: This study investigated the impact of treated wastewater (TWW) irrigation on antibiotic resistance genes (ARGs) in subsoil pore-water, finding that TWW irrigation increases ARG prevalence. The hypothesis was validated through field and laboratory experiments, showing that TWW irrigation promoted the spread of ARGs in subsoil pore-water.

Summary: This study analyzed the contribution of surface and tap water to the resistome of overhead-irrigated chive plants and found that water quality significantly affects the resistome of irrigated produce. Water played a major role in antibiotic resistance gene enrichment, especially beta-lactam ARGs and MGEs. Various antibiotic resistance genes were identified in both water sources and chive plants, with bla(KPC) detected at high levels in both.

Summary: The study revealed a significant presence of ARGs in commercial aquaculture ponds in Bangladesh, with multidrug resistance genes being the most common. Research ponds managed by the Bangladesh Agricultural University showed the lowest abundance and diversity of ARGs. The composition of ARGs displayed a distinct biogeographical pattern, potentially influenced by different feed types.

Summary: The study found that cattle farm wastewater contains abundant antibiotic resistance genes, which can be gradually reduced in concentration through anaerobic treatment, phosphorus sludge digestion, membrane bioreactor, and ozone disinfection. The concentrations of ARGs are positively correlated with wastewater quality indicators, and there is also a positive correlation between iARGs and Bacteroidetes, Firmicutes, and Spirochaetes.

Summary: Manure from swine livestock contains pathogenic bacteria and resistance genes against veterinary and clinically critical antibiotics, posing potential health risks. Comparative measurements of manure and hospital wastewater show the presence of facultative pathogens and critical resistance genes, indicating a risk for the dissemination of these genes.

Summary: This study analyzed a broiler farm that has never used antibiotics and found that not using antibiotics does not fully reduce the load of antibiotic resistance genes (ARGs) in meat processing environments. In addition, other sources of ARGs, including the production phase and breeding stage, should be considered.

Summary: The usage of antibiotics in animal production contributes significantly to the presence, supply, and spread of antibiotic resistance genes (ARGs) in the environment. This study compared and analyzed the prevalence of ARGs, mobile genetic elements (MGEs), and bacterial communities in a representative pig farm and neighboring fish ponds around Poyang Lake in China. The findings revealed that ARG contamination was more severe in the pig farm than in the fish ponds, and the water treatment plant in the pig farm was not effective. Factors such as MGEs, bacterial communities, and water quality indicators were found to co-drive the abundance of ARGs.

Summary: Our study in Jaipur City, India, found lower abundance of ARGs in a hospital wastewater treatment plant compared to municipal wastewater treatment plants, which showed enrichment of tetracycline and macrolide-lincosamide-streptogramin resistance genes. Hospital wastewater had a higher abundance of genes conferring resistance to disinfectant-related compounds. Additionally, a strong correlation was found between the numbers of ARGs and BMRGs potentially harbored by common hosts in wastewater systems with more chemicals.

Summary: The study found a significant increase in the number of antibiotic resistance genes in hospital wastewater during a specific time period in summer 2020. Two hospitals using different amounts of antibiotics had significantly different resistance gene profiles, with carbapenem resistance genes being more prevalent and abundant in one hospital.

Summary: This study combines photocatalytic technology with constructed wetlands to efficiently remove antibiotic resistance genes (ARGs). Results show that photocatalysis and constructed wetlands together increase the effectiveness of ARGs removal, with different mechanisms for intracellular and extracellular ARGs. The addition of nano-TiO2 alters the microorganisms in constructed wetlands, leading to an increase in the removal of potential hosts for target ARGs.

Summary: The reuse of household greywater is increasing globally, however, wastewater and greywater treatment processes are not fully effective in removing all contaminants. The dynamics between emerging micropollutants and antibiotic resistance genes in greywater treatment systems are complex. More studies are needed to understand the fate and transport of emerging micropollutants, antimicrobial-resistant bacteria, and antibiotic resistance genes in microbial communities and soil properties.
