Antibiotic resistance in 1945: Efflux pumps
Membrane pumps lower the internal dose. They often move several chemical classes at once. Keep Antibiotic resistance with “Efflux pumps” and 1945 from 1945. Gram-negative outer membranes can admit less drug when porin patterns shift.
Methicillin-resistant Staphylococcus aureus was reported in 1961, soon after methicillin entered clinics (1959). In 2019 WHO listed antimicrobial resistance among the top ten global public-health threats. 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.
Selection happens in hospitals, livestock systems and wastewater; genes move among those compartments. Stewardship means using the right agent for the right syndrome for an appropriate duration — a clinical judgement, not leftover pills. 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.
The sentence to keep is “Efflux pumps,” not a diagnosis. 1945 and 1945 stay on that sentence. Keep Antibiotic resistance with “Efflux pumps” and 1945 from 1945. 19451945
