A study by SMS Medical College Jaipur reveals that 60–80% of antibiotics are becoming ineffective due to rising antimicrobial resistance. The findings highlight growing failure of common drugs, increasing multidrug resistant infections, and the urgent need for rational antibiotic use, stricter regulation, and stronger antimicrobial stewardship in India.

Antimicrobial resistance has emerged as one of the most serious public health challenges of the modern era. Recent findings from SMS Medical College and Hospital, Jaipur, indicate a substantial decline in the effectiveness of commonly used antibiotics against bacterial infections. The data suggest that a large proportion of routinely prescribed antimicrobial agents are no longer producing the desired therapeutic response, raising serious concerns about the future of infectious disease management.
A multi centre observational study conducted over a two year period across five hospitals evaluated nearly ten thousand patient samples. The results demonstrated that approximately 60 to 80 percent of tested antibiotics showed significantly reduced effectiveness. In several categories, resistance levels ranged from 57 to 90 percent, while in certain bacterial isolates, resistance was observed in up to 98 percent of samples. These findings indicate a widespread and escalating resistance pattern across multiple commonly used antimicrobial agents.
The study documented high resistance rates to several widely used antibiotics, including beta lactams, fluoroquinolones, and even higher end broad spectrum agents. Alarmingly, resistance was also observed against carbapenems, which are typically reserved for severe and life threatening infections. This trend reflects a narrowing of effective therapeutic options for clinicians and increases the risk of treatment failure in routine clinical practice.
The surveillance data revealed a growing prevalence of multidrug resistant bacterial species, particularly among pathogens commonly associated with hospital acquired infections. These organisms demonstrate resistance to multiple antibiotic classes simultaneously, significantly limiting available treatment choices and increasing the complexity, cost, and risk associated with patient management.
The World Health Organization categorizes antibiotics into three groups: Access, Watch, and Reserve. The current findings indicate that substantial resistance has developed within both the Access and Watch categories, which form the backbone of routine antimicrobial therapy. As a consequence, clinicians are increasingly compelled to rely on Reserve category drugs, which are intended to be used only as last line agents.
Experts from the Department of Microbiology at SMS Medical College have identified multiple contributing factors to the rapid rise in antibiotic resistance. These include inappropriate prescribing practices, self medication, use of antibiotics for non bacterial illnesses, excessive consumption in hospital settings, and widespread application of antibiotics in animal husbandry. Additionally, environmental contamination from pharmaceutical waste has further accelerated the selection and spread of resistant organisms.
Following the COVID 19 pandemic, antibiotic consumption has increased substantially, often without appropriate clinical indications. This excessive and frequently unjustified exposure to antimicrobial agents has intensified selective pressure on microorganisms, further accelerating the development and dissemination of resistance.
A major concern highlighted by experts is the stagnation in the development of new antibiotics. While bacterial resistance continues to expand and diversify, the introduction of novel antimicrobial drugs has been limited, creating a widening gap between clinical need and available therapeutic options.
Senior academic clinicians have emphasized that antimicrobial resistance now constitutes a global health emergency. There is an urgent need for stricter regulatory frameworks governing the sale and distribution of antibiotics, ensuring that these drugs are available only through qualified medical prescription.
The importance of antimicrobial stewardship has been strongly reinforced, with emphasis on the principles of selecting the appropriate drug for the appropriate patient, using the correct dose, for the appropriate duration, and discontinuing therapy at the appropriate time. Adherence to these principles is essential to preserve the remaining effectiveness of existing antibiotics.
National and international surveillance agencies have been monitoring antimicrobial resistance for over a decade. Global estimates indicate that more than one million deaths annually are now directly attributable to drug resistant infections, underscoring the scale and urgency of this crisis.
While, current evidence does not suggest that all antibiotics have become ineffective. However, the rapid expansion of resistant bacterial strains represents a critical and accelerating threat to modern medicine. Without immediate and coordinated interventions in prescribing practices, regulation, and public awareness, the effectiveness of antimicrobial therapy will continue to erode, with profound consequences for healthcare systems worldwide.
ProtoRadNet, an explainable AI model developed at IISER Bhopal, can interpret MRI, CT and X ray scans like a radiologist. Built over 1.5 years and tested on public datasets with 92% accuracy and 190+ clinical reports, the system highlights suspicious regions and explains findings. This innovation could help address India’s radiologist shortage and improve diagnostic speed.
A first-of-its-kind genomic study from India has revealed that the Mpox case detected in Kerala was caused by the Clade Ib variant imported through international travel from Dubai. Genetic sequencing traced the virus’s journey into India, uncovered dangerous mutations, and warned that this evolving strain may spread faster and wider through sustained human transmission.
