Document Summary

Antibiotic resistance is becoming a huge concern. The only defense is to be careful with the antibiotics, but this is not always the case. Vancomycin is the antibiotic of last resort, and there are some reports of resistance to that. The more an antibiotic is used, the lower the likelihood that it will maintain its effectiveness. About 11 million of the 13 million kg of antibiotics produced annually in north. Some people also thins the intestinal wall and increases nutrient absorption. But this leads to the flourishing of antibiotic-resistant bacteria in animals and these bacteria can infect humans: chickens begin to excrete antibiotic-resistant e. coli in their feces just 36 hours after being given tetracycline-laced feed. These also show up in the feces of farmers. This means that bacteria that have never been exposed to an antibiotic can acquire resistance just by encountering resistant ones.
