[Antimicrobial resistance forever? Judicious and appropriate use of antibiotics]

Area of Science:

• Microbiology
• Pharmacology
• Infectious Diseases

Background:

• Commemorates the 70th anniversary of Sir Alexander Fleming's original work on penicillin, published in 1946.
• Highlights the historical context of antibiotic discovery and its initial impact.

Observation:

• The rapid emergence of bacterial resistance to antibiotics was unforeseen at the time of penicillin's discovery in 1928.
• Every new class of antibiotics introduced has been followed by the development of resistant bacterial strains.

Findings:

• Bacterial resistance to antibiotic treatment poses a significant global health threat.
• The development of antibiotic resistance has outpaced the introduction of new treatments.

Implications:

• A US action plan targets a 50% reduction in antimicrobial resistance over the next five years.
• Urgent strategies are needed to combat the escalating challenge of antimicrobial resistance.
