Sulfamethoxazole, tetracycline and oxytetracycline and related antibiotic resistance genes in a large-scale landfill, China

Methanogen Community Dynamics and Methanogenic Function Response to Solid Waste Decomposition

“…DNA of solid waste samples was extracted by EZNA ® Soil DNA Kit (Omega Bio-Tek, Norcross, GA, United States). Extracted DNA quantification and quality assessment followed a previously reported method ( Song et al, 2016 ). DNA extraction was performed in triplicate for each sample.…”

Contribution of antibiotics to the fate of antibiotic resistance genes in anaerobic treatment processes of swine wastewater: A review

“…Li et al (2015) also indicated that the correlation not only just occurred between ARGs and theircorresponding antibiotics, but is still true for other types of antibiotics, for instance, the slufamerazine indicated a positive relationship with tetracycline resistance genes (tetB and tetC). In a landfill, OTC and TC showed positive correlations with tetO and sul1, total while SMX was not found to be associated with the ARGs investigated(Song et al, 2016). Also, a high concentration of OTC could improve the relative abundance of drfA7, a sulfonamide resistance gene(Qian et al, 2016).…”

“…Integrons are ubiquitous in chromosomes and MGEs, like plasmids and transposons(Chen et al, et al, 2009). They play a key role in the dissemination of ARGs by facilitating horizontal transfers of ARGs between microbes through combination with mobile gene platforms and/or incorporating ARGs into microbial chromosomes(Gillings et al, 2015;He et al, 2016). Class 1 integrons were often used to represent the HGT as it can regulate the expression of exogenous genes.…”

Environmental geotechnics: challenges and opportunities in the post-Covid-19 world

“…-Existence and transport of ARGs in landfilled MSW (Song et al 2016, Wu et al 2017), leachate (Yu et al 2016, and the surrounding environment (Chen et al 2017).…”
