Do antibiotics cause bacteria to become resistant?
Yes, over use of antibiotics can cause bacteria to become resistant.
are Antibiotics are useful for limiting the growth of most pathogenic bacteria?
no, many bacteria have become resistant due to improper use of antibiotics.
What are antibiotics and how are they use?
Antibiotics are substances that kill bacteria. They are not able to neutralise viruses. Bacteria can become resistant to antibiotics, so misusing them for non-bacterial infections could have serious consequences rendering the antibiotic ineffective.
Why does mutant bacteria survive in hospital environments?
Hospitals are rich with antibiotics. These will kill most bacteria, but those that survive often become resistant. At a hospital bacteria can become resistant to a variety of antibiotics and can pass from one patient to another, many of whom already have weakened immune systems. It is a good example (for the bacteria anyway) of "what doesn't kill you only makes you stronger."
Why is the overuse of antibiotics a problem?
It exposes too many organisms to antibiotics, and exposing them too frequently. This results in the opportunity for the organisms to become resistant to the antibiotics. Antibiotic resistant bacteria are becoming a more and more serious public health threat.
What is one advantage of restricting the use of antibiotics?
The germ causing the infection can become resistant ("immune") to the antibiotic, then it will basically make it useless in the fight against that germ.
MRSA mutation process?
Bacteria have the ability to mutate and become resistant to elements that are attempting to destroy them, such as antibiotics. As a result of abuse and overuse of antibiotics, there are not antibiotic-resistant strains of bacteria such as MRSA and VRE. Even though antibiotics have become less effective in destroying these mutated superbugs, Manuka Honey is not being used to kill MRSA and effectively treat Staph infections.
Why won't som antibiotics cure bacterial?
One possible reason could be that the bacteria has some how become resistant to the antibiotics used to fight it. If you take a certain antibiotic often, your body will start to become immune to its effects. Then when that antibiotic is needed to fight a bacteria, your body no longer registers the antibiotics as a way of killing the bacteria.
Why does not finishing an antibiotic contribute to antibiotic resistance?
When you take antibiotics, you start killing the bacteria in your body. The first ones to die are the ones that are mostly easily killed by the drug. Bacteria are very variable, however, so some of the bacteria in your body will be more able to resist the drug. For example, they might have an enzyme that gives them some protection from the drug. If you take all of your prescription, you might eventually overwhelm even these slightly resistant bacteria, killing them. If you stop taking your antibiotics early, however, the more resistant bacteria may survive. When they reproduce, they pass their resistance along to their offspring. As bacteria reproduce, more changes occur in their DNA so slightly resistant bacteria can become even more resistant. So, not finishing your antibiotic increases the chances of letting resistant bacteria survive to reproduce and make resistant offspring, that may become even more resistant with time.
Which bit of MRSA mutates?
Bacteria have the ability to mutate and become resistant to elements that are attempting to destroy them, such as antibiotics. As a result of abuse and overuse of antibiotics, there are not antibiotic-resistant strains of bacteria such as MRSA and VRE. Even though antibiotics have become less effective in destroying these mutated superbugs, Manuka Honey is not being used to kill MRSA and effectively treat Staph infections.Read more: Mrsa_mutation_process
Is that just a myth that one should complete the course of antibiotics?
No. Obviously not. If a patient does not complete a course of antibiotics, they run the risk of selecting for antibiotic resistant bacteria in their body. If these bacteria become infectious, stronger (more expensive) antibiotics will be required to treat the secondary infection.
A paragraph on antibiotics ''why antibiotics are not overused?
The more antibiotics are used, the more likely it is for antibiotic resistant organisms to appear. The germ causing the infection can become resistant ("immune") to the antibiotic, then it will basically make it useless in the fight against that germ. Antibiotics are medicines that are used to kill or stop the reproduction in bacteria. Antibiotics are mainly used to stop infections or infectious diseases, and since its discovery,If antibiotics is overused it may kill the benefitical bacteria in our body if we take unneccesarly the drugs become less effective .Antibiotics, however,are not effective against cold and flu as these are caused by viruses.
