A Nature Communications study found high concentrations of antibiotic residues in urban Indian sewage have accelerated selection for antimicrobial resistance across microbial communities. Researchers sampled multiple city sewage systems and showed environmental exposure levels correlated with increased abundance of resistance genes and resistant strains. The work links pharmaceutical pollution to measurable shifts in resistomes, raising alarms for wastewater management and surveillance. The study quantified drug residues and resistome composition using metagenomics and chemical assays, implicating untreated or poorly treated effluent as a key driver. Authors call for tighter controls on pharmaceutical discharge, improved wastewater treatment infrastructure and integration of environmental reservoirs into AMR monitoring frameworks. For biotech and diagnostics companies, the paper underscores growing demand for environmental AMR surveillance tools and interventions that remove or degrade antibiotics from wastewater to blunt resistance emergence.
