Antibiotic resistance genes (ARGs) are considered to be emerging pollutants related human activities. The rapid development of global urbanization has expanded activities, thereby exacerbating the health risks caused by antibiotic genes. effects urban and rural environments multifarious, which makes source distribution ARGs in environment diversification. Understanding spread is essential for s...

BACKGROUND Antimicrobial agents have been widely used in animal farms to prevent and treat animal diseases and to promote growth. Antimicrobial agents may change the bacterial community and enhance the resistome in animal feces. We used metagenome-wide analysis to investigate the changes in bacterial community, variations in antibiotic resistance genes (ARGs), and their bacterial hosts in the f...

BACKGROUND Growing concerns about increasing rates of antibiotic resistance call for expanded and comprehensive global monitoring. Advancing methods for monitoring of environmental media (e.g., wastewater, agricultural waste, food, and water) is especially needed for identifying potential resources of novel antibiotic resistance genes (ARGs), hot spots for gene exchange, and as pathways for the...

Although dairy manure is widely applied to land, it is relatively understudied compared to other livestock as a potential source of antibiotic resistance genes (ARGs) to the environment and ultimately to human pathogens. Ceftiofur, the most widely used antibiotic used in U.S. dairy cows, is a 3rd generation cephalosporin, a critically important class of antibiotics to human health. The objectiv...

High concentrations of residual arsanilic acid occur in pig manure due to its use in feed to promote growth and control diseases. This study compared the effects of arsanilic acid at three concentrations (0, 325, and 650mg/kg dry pig manure) on the abundance of antibiotic resistance genes (ARGs) and the microbial community during anaerobic digestion. Addition of 650mg/kg arsanilic acid enhanced...

Antibiotic resistance has become a global threat in which the anthropogenically influenced aquatic environment represents not only reservoir for spread of antibiotic resistant bacteria (ARB) among humans and animals but also an where genes are introduced into natural microbial ecosystems. Wastewater is one sources resistance. The aim this research was evaluation wastewater impact on water envir...

Abstract Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for waste to promote recycling, has identified also aid ARG reduction. However, the effect composting re...

The pollution of antibiotic resistance genes (ARGs) in livestock farms is a problem which need to be paid more attention to, due to the severe resistance dissemination and the further human health risk. In this study, all the relevant exposure matrices (manure, soil and water) of sixteen animal farms in Southeastern China were sampled to determine twenty-two ARGs conferring resistance to five m...

The spread of antibiotic resistance genes (ARGs) caused by biofilm growth in drinking water distribution systems (DWDSs) poses a serious threat to human health. influence disinfection by-products (DBPs) on the ARGs and mobile genetic elements (MGEs) different phases (biofilms water) DWDSs is unclear. In this study, characteristics microbial indices, trihalomethanes (THMs), haloacetic acids (HAA...

Antibiotic resistant bacteria are ubiquitous in the natural environment. The introduction of effluent derived antibiotic resistance genes (ARGs) into aquatic environments is of concern in the spreading of genetic risk. This study showed the prevalence of sulfonamide and tetracycline resistance genes, sul1, sul2, sul3, and tet(M), in the total bacterial assemblage and colony forming bacterial asse...
