चर्चा में क्यों
Scientists at CSIR–CCMB conducted a wastewater study revealing widespread Antimicrobial Resistance (AMR) in Delhi, Mumbai, Kolkata, and Chennai, advocating for real-time pathogen surveillance.
पृष्ठभूमि
The study analyzed 447 wastewater samples from four major Indian cities. It identified that bacteria developed resistance through specific genes capable of being shared between bacteria, thereby reducing antibiotic effectiveness.

मेन्स के लिए
Q. Discuss the public health implications of Antimicrobial Resistance (AMR) in urban India and evaluate the feasibility of wastewater-based surveillance as a proactive mitigation strategy.
उत्तर के आयाम
- Surveillance gap: Lack of standardized real-time pathogen tracking in municipal sewage systems
- Biological risk: Horizontal gene transfer facilitating rapid spread of multi-drug resistant bacteria
- Policy trade-off: Balancing infrastructure costs of wastewater treatment with public health safety
