Mobile Genetic Elements and Reservoir Type Drive Resistance-Gene Abundance in Water Sources

Aquatic environments are recognized as reservoirs and pathways for antimicrobial resistance, receiving antibiotic residues and resistant microorganisms from sewage, livestock farming, and aquaculture. Previous studies have detected resistance genes in drinking water sources and shown that conventional treatment may remove them incompletely.

Korean Researchers Identify New Mechanism Underlying Superbug Antibiotic Resistance

A joint research team led by Professor Hongbaek Cho of the Department of Biological Sciences at Sungkyunkwan University (SKKU) and Professor Jeong Min Chung of the Department of Biotechnology at The Catholic University of Korea has identified a new mechanism underlying antibiotic resistance in Pseudomonas aeruginosa, a major multidrug-resistant "superbug."

Gene Amplification Unexpectedly Increases Bacterial Susceptibility to Frontline Antibiotics

This study was led by Yuqin Song and Jie Feng from the Institute of Microbiology, Chinese Academy of Sciences. The researchers investigated how insertion sequence (IS)-mediated gene amplification contributes to the adaptability of Acinetobacter baumannii, an important nosocomial pathogen known for its multidrug resistance and persistence in clinical environments.
