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
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
How Do Health Care Associated Infections Lead To Antibiotic Resistance? The use of antibiotics (and other antimicrobial agents) can lead to disease-causing bacteria developing resistance, making it more difficult to treat patients’ infections. These resistant organisms can spread from person to person, with the potential to cause serious and difficult-to-treat infections. How do infections develop
