There's a worry that using too many drugs to fight infections is making bacteria stronger and harder to treat in both people and animals.!
The study looked at 14 farms with cows, sheep, and pigs in England to see how the use of these drugs and farming practices affected bacteria that resist treatment over time.!
Results showed pig farms had more resistant bacteria than sheep farms, even when they used fewer drugs, suggesting that there are other reasons making pigs more susceptible to these strong bacteria.!
