Antibiotics have been one of humanity’s success stories for hundreds of years, saving millions of lives and enabling huge advances in medical and surgical care. But this success has come at a price. The growing resistance of many bacterial strains to the curative effects of antibiotics is so concerning that it has been called, in some quarters, the greatest threat to our continued existence on earth.
The reason why pharmaceutical corporations find antibiotic development unprofitable.
E. The consequences of this trend are alarming. We are entering what the World Health Organization (WHO) has termed a "post-antibiotic era." In this scenario, common infections and minor injuries would once again become lethal. Routine surgeries, such as hip replacements or caesarean sections, would carry a high risk of mortality due to untreatable infections. Furthermore, modern medical treatments that suppress the immune system, such as chemotherapy for cancer, would become incredibly dangerous without effective antibiotics to protect patients from opportunistic infections. The economic impact is equally stark; the World Bank predicts that by 2050, antimicrobial resistance could cause a decline in global GDP comparable to the shock of the 2008 financial crisis.

A. The discovery of penicillin by Alexander Fleming in 1928 is often cited as one of the most significant milestones in medical history. For the first time, humanity possessed a weapon against bacterial infections that had historically been fatal. Diseases such as pneumonia, tuberculosis, and sepsis became treatable, and the average life expectancy rose significantly. This "golden age" of antibiotics ushered in an era of surgical safety; complex operations became routine because doctors could reliably prevent post-operative infections. However, less than a century later, this medical triumph is in jeopardy. We are now facing a global crisis where the drugs used to treat infections are losing their efficacy, a phenomenon known as antibiotic resistance.
The growing global threat of antibiotic resistance is a pressing concern that requires immediate attention. The overuse and misuse of antibiotics have led to the emergence of antibiotic-resistant bacteria, making it challenging to treat infections.
