How Bacterial Species Evolve Antibiotic Resistance
farmers used them freely.Now scientists know that the overuse of antibiotics can cultivate drug-resistant bacteria that are dangerous to human health.Among debates over what kinds of restrictions should be put in place.figuring out how antibiotic-resistant bacteria evolve and make th...
it protects the host against colonization by many external pathogens.8It is also a known reservoir for a wide variety of antibiotic resistance genes, from the resident “friendly” non-pathogenic bacteria and gut-dwelling opportunistic pathogens, as well as transient bacteria...
Currently, most commonly used antibiotics work by attacking the cell walls of bacteria or preventing the production of growth proteins. However, over time bacteria evolve and develop resistance. This growing trend has scientists worried, with experts warning that the lack of antibiotics effective agains...

tracts, bones and joints, and is a serious threat to patients with severe burns, cystic fibrosis and cancer. “With increased incidence of antibiotic resistance and a trend toward single-site super-hospitals, there is a growing need for greater understanding of how bacteria evolve,” said ...
"Antibiotic resistance often evolves by mutations in genes that are conserved across bacteria, raising the possibility that resistance evolution might follow similar paths across bacteria," said colleague Craig MacLean. "Our study provides good evidence that the rest of the genome influences which resist...
” Just as animals evolve to evade predators or survive in harsh climates, bacteria evolve to withstand the things that threaten them—and these include antibiotics. “Bacteria with an antibiotic resistance gene can survive where nonresistant bacteria do not,” says Buboltz. These survivors then ...
