Antibiotics are generally targets a potential life process of pathogen. If a pathogen mutates its protein for example it may be complete different than the previous and may even changes its function slightly different. Thus the antibiotic that are acting on the previous form of a protein acts no more on this newly mutated protein because of its specificity.

Why aren't all mutations bad?
Mutations are unnatural changes in the body or behavior. They are not always bad. For instance, the skin of the poison tree frog is not really bad at all. It rubs itself on poison leaves and mutated itself not to be affected.
How do mutations relate to traits?
Mutations cause certain traits.
What is an example of what a mutation can cause?
Mutations can cause diseases such as cancer
What cell cause mutations?
DNA polymerase
Describe the enviormental factors that could result in mutations?
Chemical mutagens are chemicals that cause mutations in DNA. They can bind with DNA, take the place of base pairs (base analogs), or alter the structure and bonding properties of bases (such as nitrous acid).Ionizing radiation can cause mutations in DNA also. This includes gamma rays found in sunlight. The radiation causes some compounds to become free radicals, which have unpaired electrons and are very reactive chemically. In cells these radicals can react with sections of DNA and cause mutations.*Ionizing radiation is why bacteria are killed by sunlight.
A mutation that causes antibiotic resistance in bacteria is a what mutation?
Missense mutation Nonsense mutation Frameshift insertion Frameshift deletion All may cause antibiotic resistance in bacteria
What is the problem with bacteria resistant to antibiotics?
Because if some bacteria survive the antibiotics they become immune to that type of antibiotic. Then if you pass on the bacteria again the next person will not know which type of antibiotic to use.
How can one be antibiotic resistant?
People do not develop a resistance to antibiotics, instead bacteria in the body resist the effects of the antibiotic. The bacteria changes somehow and instead of the antibiotic eliminating it, the bacteria survives and continues to cause harm and infection. Some bacteria neutralizes the antibiotic, others fight and flush out the antibiotic, and the others modify where the antibiotic goes.
How does hand hygiene fight antibiotic resistance?
because our hands life many microbes so you must wash your hands mostly. they cause antibiotic resistance when you eat some microbes, you feel stomach pain you eat small dose of antibiotics then bacteria become resistance the some antibiotics
Why is it a problem in medicine for anibiotic resistance?
Antibiotic resistance happens when taking antibiotics more that it is required, high frequent doses will cause bacterial antibiotic resistance because in this case bacteria will get use into certain drug and so become ineffective. Resistance also happen when the patient has frequent illness, which make him/her taking the antibiotic for a long period of time. At that point patient should go the physician to describe him/her another effective drug, in order to kill bacteria and stop the illness.
Can plasmids be transferred into other bacteria?
Plasmids are often transferred to other bacterial cells via the sex pilus. This mechanism is a major cause in the spread of antibiotic resistance genes.
Can antibiotics cause resistance in bacteria?
A simple way to explain it is:When you have an infection and take antibiotics for it, the weaker bacteria are killed first, with the stronger ones surviving, or taking longer to destroy. So when you don't take the full round of antibiotics, the stronger bacteria are the ones left in your body, and they are the ones that will continue to multiply, resulting in a bacteria resistant to the antibiotic. This is why you should always take the full prescribed course of antibiotics.Also, when antibiotics are prescribed, the body's natural defense system (the good bacteria) are destroyed along with the bad bacteria. This is why you should always eat yogurt with active cultures or drink buttermilk while on antibiotics - the active cultures put the "good" bacteria back in the body.
Do ciprofloxacin help with inflammation?
Depends on the cause of the inlammation - ciprofloxacin is a broad-spectrum antibiotic (it inhibits the DNA gyrase, an important enzyme for bacteria), so it might help if the inflammation is caused by bacteria without resistance against ciprofloxacin.
Some bacteria strains may acquire resistance to antibiotics and or the ability to cause disease by acquiring what?
Some bacteria strains may acquire resistance to antibiotics and/or cause a new disease by gaining spores from other bacteria.
What best explains why mutations cannot cause evolution?
Biology has catalogued many traits produced by point mutations (changes at precise positions in an organism's DNA)--bacterial resistance to antibiotics, for example.To say otherwise is incorrect.But mutations do cause evolution. Biology has catalogued many traits produced by point mutations (changes at precise positions in an organism's DNA)--bacterial resistance to antibiotics, for example.To say otherwise is incorrect.
What is antibiotic resistance and how does it occur?
Bacteria and other microorganisms that cause infections are remarkably resilient and can develop ways to survive drugs meant to kill or weaken them. This antibiotic resistance, also known as antimicrobial resistance or drug resistance, is due largely to the increasing use of antibiotics.
Why do some people become resistant to certain antibiotic?
Antibiotic resistance results from misusing antibiotics. Antibiotics should only be used to treat bacterial infections. Many industrial farmers will give healthy animals a daily dose of low level antibiotics to stimulate growth. These daily doses help to create antibiotic resistant super bugs.
