How can bacteria be resistant against antibiotics discuss at least 3 mechanism
Ans:- 3 mechanisms of bacterial resistance to antibiotics are as follows:-
1. Decrease permeability,
2. Activation of drug pumps,
3. Change in drug binding sites.
1. Decrease permeability :- In this mechanism the receptor that transports the drug is altered so the drug cannot enter the cell and bacteria becames resistant for the antibiotics.
2. Activation of drug pumps:- In this mechanism specialised membrane proteins are activated and continually pump the drug out of the cell and bacteria became resistant.
3. Change the drug binding sites:- In this mechanism binding site on target ribosome is altered so drug has no effect on bacteria.

Drug Resistant Bacteria There are bacteria that is resistant to many antibiotics which makes it difficult to treat. Look up MRSA, VRE and VRSA and give a short synopsis of each. What can you tell patients to make sure that they will not become resistant to antibiotics?
Antibiotics has led to development of bacteria resistant to antibiotics. Which led to stronger antibiotics, with the understanding of the theory of evolution from Darwin, particularly natural selection, explain the phenomenon.
Question 13 Microbes can become resistant to antibiotics and prevent the antibiotics from damaging them. Why? (Select all that apply) When bacteria reproduce, chance mutations that can protect the bacterium against a particular antibiotic occur. Bacteria reproduce very fast. The antibiotic changes the DNA of the bacterial cells. While most of the bacteria succumb to the antibiotic, the few that survive go on to reproduce and replicate the resistance. In any large population of bacteria, a few cells will be...
Briefly describe why natural selection results in bacteria that are resistant to antibiotics. How does this relate to the characteristics of life?
3. What are two ways by which bacteria can overcome (or resist) the effects of antibiotics (i.e., what are 2 things bacteria can do to antibiotics so they do NOT work against bactertia)? Which form of DNA is most likely to contain genes that specify antibiotic resistance? 4. Some bacteria can stop the activation of complement. Suggest how this might be accomplished (ie- suggest 2 or 3 things bacteria might do to complement to stop or prevent complement activation). Describe...
The use, overuse, and abuse of antibiotics are accredited with creating antibiotic-resistant strains of bacteria. Explain how this relates to natural selection. Are there things that you can personally do to reduce your risk or even to reduce the spread of these dangerous microbes?
which of the following is not a wag thag bacteria become resistant to antibiotics a. blocking entry b. inactivation by enzymes c. alteration of target molecules d. forming an endospore to avoid the antibiotics
1. Two million people in the US becoming infected with bacteria that are resistant to antibiotics, and at least 23,000 people dying each year as a direct result of these infections. Write 4-5 sentences of a public service announcement that would educate the public on antibiotic resistance and a prevention strategy. (Public Service Announcements are run on TV and radio to inform the community about safety and health information)
2. Researchers in Israel have developed a novel method of restoring antibiotic sensitivity to resistant bacteria, according to a study in the journal Applied and Environmental Microbiology. The process could eventually be used to fight hospital superbugs, researcher said. An estimated 70% of hospital acquired infections in the U.S. involve bacteria that are resistant to at least one antibiotic. Using a process called lysogenization, scientists used bacteriophages, viruses that can infect bacteria, to invade resistant bacterial cells and restore their...
Two million people in the US becoming infected with bacteria that are resistant to antibiotics, and at least 23,000 people dying each year as a direct result of these infections. Review the CDC article in this weeks lecture, and your Davis Drug guide under anti-infectives. Public Service Announcements or PSA's are run on TV and radio to inform the community about safety and health information.. This week you will be writing and performing you own PSA for the class. 1....
