Can Resistant Bacteria Be Cured? Standard antibiotics can’t kill bacteria that have become resistant. Many of these germs have spread all over the world. These bacteria can cause infections. They can be very hard to treat. Does antibiotic resistance go away? Without the selective pressure of antibiotics killing off the competition, bacteria with this mutation
How Has The Misuse Of Antibiotics Led To Bacterial Resistance? Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. How has
Is Resistant Bacteria An Example Of Natural Selection? Over time, bacteria can become resistant to certain antibiotics (such as penicillin). This is an example of natural selection. How does antibiotic resistance affect natural selection? Survival of the Fittest (Natural Selection) When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will
