why are scientists looking for an alternative to antibiotics
Answers
Answer:
They communicate more effectively with one another and exchange information more quickly. In addition, they can switch on and off genes that make them harmful. "These properties make the bacteria more resistant to antibiotics and to the host's immune response
The antibiotic resistance problem is caused by the evolution and transfer of genes that confer resistance to medically important antibiotics into human pathogens. The acquisition of such resistance genes by pathogens complicates disease treatment, increases health care costs, and increases morbidity and mortality in humans and animals. As antibiotic resistance continues to evolve, antibiotics of so-called last resort become even more precious. Reducing or preventing the dissemination of antibiotic resistance genes into human pathogens is currently of high international importance.
