Abstract:

Antibiotic resistance genes(ARGs)are emerging contaminants, whose spread in the environment exacerbates antibiotic resistance issues. Little is known about the critical and shared antibiotic resistance genes(ARGs)and their potential hosts in human and water environments. Here, we characterized the ARG profile and bacterial community in human and water environments from a Chinese rural village using high-throughput quantitative polymerase chain reaction and 16S rRNA gene sequencing. A total of 70 shared ARGs, 7 shared mobile genetic elements(MGEs), and 58 shared bacteria between human and water environments were identified. The dominant shared ARGs in feces were both tetracycline and MLSB resistance genes. Further, we identified 20 bacterial biomarkers by linear discriminant analysis effect size(LEfSe). The network revealed a significant association among shared ARGs, MGEs, and bacteria(P < 0.05), suggesting the potential transfer of ARGs between humans and environments via these bacteria. This study revealed the shared ARGs in drinking water, feces, skin, wastewater, and river samples. Our results may provide a better understanding of the co-occurrence of these genetic elements and identify the potential hosts of ARGs between humans and the environment in peri-urban areas. In conclusion, this study demonstrated the co-occurrence and transmission of shared ARGs and bacteria in humans and water environments.
