Soil warming increases the active antibiotic resistome in the gut of invasive giant African snails by Yiyue Zhang, Hong-Zhe Li, Martin Breed, Zhonghui Tang, Li Cui, Yong-Guan Zhu, Xin Sun

“…Among 299 high-quality ARG-carrying metagenome-assembled genomes (MAGs), we further revealed that the soil warming enhances the abundance of “supercarriers” including human pathogens with multiple ARGs and virulence factors. Furthermore, we identified elevated biosynthetic gene clusters (BGCs) within these ARG-carrying MAGs, with a third encoding at least one BGC. …”
