Quick facts

In his Nobel lecture Alexander Fleming warned that under-dosing penicillin would educate microbes to resist it.Fleming's 1945 warning
Methicillin-resistant Staphylococcus aureus was reported in 1961, soon after methicillin entered clinics (1959).MRSA 1961
In 2019 WHO listed antimicrobial resistance among the top ten global public-health threats.WHO top-ten threat
The UK Review on AMR projected up to 10 million deaths a year by 2050 if resistance were left unchecked — a scenario, not a census.O'Neill 2016 scenario
Selection happens in hospitals, livestock systems and wastewater; genes move among those compartments.Three reservoirs
Stewardship means using the right agent for the right syndrome for an appropriate duration — a clinical judgement, not leftover pills.Stewardship idea

Antibiotic resistance is selection: drugs kill or stop susceptible cells, and the remainder become the story.

Hospitals, farms and wastewater are linked classrooms. Genes ride plasmids between species; that is why stewardship is social, not only personal.

This page is not a laboratory manual for creating resistant strains. It is a public-health atlas of how a miracle class of drugs is being spent.

Frequently asked questions

Is resistance a new problem?
Genes that disable antibiotics existed in soil long before clinics. Mass medical and farm use made the problem urgent.
Do people become immune to antibiotics?
No. Microbes change. A person may carry resistant strains; the drug target is the microbe, not the patient's willpower.
Why do farms matter?
Antibiotics used for growth or routine disease control select resistant bacteria that can travel via food, dust and water.
What is a priority pathogen list?
WHO (2017 onward) ranks bacteria for which new drugs are most needed, such as carbapenem-resistant enterics.
Can I finish leftover antibiotics from a friend?
That is not a plan this page can endorse. Wrong drug and wrong duration both waste a scarce resource and can harm.
Does resistance mean all antibiotics fail forever?
It means particular drug–bug pairs fail more often. Some older drugs still work for some infections; labs test isolates.
How does wastewater fit?
Excreted drugs and bacteria meet in treatment plants and rivers, a quiet classroom for exchanging genes.
Is this medical advice?
No. Educational only. Infection treatment and whether an antibiotic is needed are clinical decisions.
