How do antibiotic-resistant bacteria make infections harder to treat?
MedicineAntibiotics
Quick Answer
They evolve changes that let them survive drugs that once killed them. That means doctors may need different medicines, combinations or longer treatment.
The Full Story
Bacteria can become resistant through mutation or by acquiring resistance genes from other bacteria. These changes may alter the drug target, pump the medicine out of the cell or destroy the antibiotic before it works. Resistance has become a major global health problem, with pathogens such as MRSA and drug-resistant tuberculosis causing difficult-to-treat infections. Careful antibiotic use and infection prevention are key tools for slowing resistance.
Key Facts
1.resistance can spread by mutation and gene transfer
2.MRSA is a well-known drug-resistant bacterium
3.drug-resistant tuberculosis is a major public-health challenge
