BACKGROUND Animal manure is a reservoir of antibiotic resistance genes (ARGs) that pose a potential health risk globally, especially for resistance to the antibiotics commonly used in livestock production (such as tetracycline, sulfonamide, and fluoroquinolone). Currently, the effects of biological treatment (composting) on the transcriptional response of manure ARGs and their microbial hosts a...

Comprehensive studies on the effects of genetics and fiber diets antibiotic resistance genes (ARGs) remain scarce. In this study, we analyzed profiles ARGs in colonic contents fecal samples Taoyuan, Duroc, Xiangcun pigs (n = 10) fed at different levels. Through macrogenomic analysis, identified a total 850 unique types classified them into 111 drug classes. The abundance partially drug-resistan...

The increasing abundance of antibiotic resistance genes (ARGs), which are regarded as new pollutants, has raised public health concern. use antibiotics in aquaculture promoted the evolution and spread ARGs. occurrence ARGs attracted extensive attention. However, distribution transmission require further study. This study analyzed water sediment from intensive culture hybrid snakehead fish farm ...

The worldwide dispersion and sudden emergence of new antibiotic resistance genes (ARGs) determined the need in uncovering which environment participate most as their source and reservoir. ARGs closely related to those currently found in human pathogens occur in the resistome of anthropogenic impacted environments. However, the role of pristine environment as the origin and source of ARGs remain...

Post-digestate treatments may reduce the risk linked to Antibiotic Resistant Genes (ARGs) release with digestate direct land application. Thus, this study aimed evaluate post-digestate composting and co-composting biogas production feedstock (maize silage, food processing waste, poultry litter) effect on abundance of selected ARGs: erm(B), tet(K), tet(M), tet(O), tet(S) genes. More than 80% all...

Understanding fate of antibiotic resistant bacteria (ARB) vs. their antibiotic resistance genes (ARGs) during wastewater sludge treatment is critical in order to reduce the spread of antibiotic resistance through process optimization. Here, we spiked high concentrations of tetracycline-resistant bacteria, isolated from mesophilic (Iso M1-1-a Pseudomonas sp.) and thermophilic (Iso T10-a Bacillus...

Abstract Background Environmental hygiene concerns are needed to be settled before the reuse of abandoned swine feedlot sites. However, few researchers have focused on fate antibiotic resistance genes (ARGs) in soil microbiota around feedlots. In this study, we examined seasonal alterations ARGs and bacterial community composition using quantitative PCR high-throughput sequencing 16S rRNA gene....

Data concerning the occurrence of emerging biological contaminants such as antibiotic resistance genes (ARGs) and fecal indicator bacteria (FIB) in aquatic environments in Sub-Saharan African countries is limited. On the other hand, antibiotic resistance remains a worldwide problem which may pose serious potential risks to human and animal health. Consequently, there is a growing number of repo...

Abstract Antibiotic resistance genes (ARGs) are widespread among bacteria. However, not all ARGs pose serious threats to public health, highlighting the importance of identifying those that high-risk. Here, we developed an ‘omics-based’ framework evaluate ARG risk considering human-associated-enrichment, gene mobility, and host pathogenicity. Our classifies human-associated, mobile (3.6% ARGs) ...

Antibiotic resistance genes (ARGs) may be introduced to agricultural soil through the land application of cattle manure. During a rainfall event, manure-borne ARGs infiltrate into subsurface and leach groundwater. The objective this study was characterize model vertical transport following beef manure on surface. In study, column experiments were conducted evaluate influence four ARGs: erm(C), ...
