Quick Answer
Penicillin-resistant Staphylococcus aureus was documented as early as 1942.
The Full Story
Resistance to penicillin in Staphylococcus aureus was reported as early as 1942 — just one year after the drug was first used on patients. Alexander Fleming himself warned in his 1945 Nobel lecture that misuse could breed resistant bacteria. By the 1960s methicillin-resistant Staphylococcus aureus (MRSA) had emerged. The WHO now calls antimicrobial resistance one of the top global health threats, estimating it contributed to roughly 4.95 million deaths in 2019.
Key Facts
1.Fleming predicted resistance in his 1945 Nobel acceptance speech.
2.MRSA was first identified in the UK in 1961.
3.Some bacteria are now resistant to nearly all known antibiotics, earning the label "superbugs."
