Antibiotics Are Chemicals Produced By Humans And Livestock

The main use of antibiotics is to fight bacterial infections in animals. Antibiotics are chemicals commercially produced using a glorified "guess and check" approach. In this process, thousands of organisms are screened in an attempt to find potential antibiotic properties the chemicals produced by these organisms. After an organism with said properties is found, scientists are able to test the potential antibiotic on a wide variety of infections in the hope that the compound produced is effective against one or more of them. After an antibiotic-producing organism is identified, it is produced on a massive scale, and after it receives certification from the required agency (the FDA in America), the drug is able to be produced on an…show more content…
In agriculture however, antibiotics are not directly administered to plants. Rather, the manure from livestock treated with antibiotics (which could also contain antibiotic resistant bacteria) is used to fertilize crops. This facilitates the widespread long distance travel of antibiotic resistant bacteria. Through this process, an isolated population of resistant bacteria from a single farm has the potential to spread across the country and potentially world, which could have a drastically negative effect on animals and humans alike. This investigation is designed to show the difference in antibacterial resistance between two separate bacteria: E. coli and S. epidermidis. It is designed mainly to show the effect that an organism 's environment has on its ability to resist antibiotics. This is because E. coli is located inside the human body, in the intestines. In contrast, S. epidermidis is located externally, on the skin of animals. The location of a bacteria will potentially alter its ability to resist antibiotics. In the case of E. coli, the organism is isolated from external factors due to its environmental niche. Because of this it is less likely to come in contact with factors (for the purpose of this lab antibiotics) that could cause it to adapt through natural selection. But in contrast to E. coli, S. epidermidis is located on the skin, and therefore it more likely to come in contact with
