Using antibiotics when ineffective or unnecessary enables the mutation and spread of antibiotic-resistant bacterial strains, since the bacteria will get small and/or a short duration of doses of the medicine, too short to kill the bacteria, but able to make them get used to the "poison" and no longer killed by it. That is why you are told by medical professionals that you should always take all antibiotics prescribed even when you start feeling better, because it takes the full amount of medicine to be sure the bacteria have been killed. You are also told not to skip doses for the same reason.
Do not pressure your physician to prescribe antibiotics for a cold. Antibiotics are not a direct treatment of viruses that cause colds and flu, they have no affect on any viruses. They are only prescribed with viral illness if there has been a secondary bacterial pneumonia or other bacterial infection develop.
If you take antibiotics when unnecessary, you also contribute to the production of more antibiotic-resistant bacteria. It is coincidental when people say that they know that the antibiotics they took for a cold or flu virus made them feel better. It is a matter of time, not medicine. Often people do not seek physician exam until they have had a cold for 5-7 days...and then within 3 days of starting the antibiotics, they begin to feel better and attribute it to the antibiotics. But it is not due to the medicine, it is due to the time it took your body to rid the virus, which is in 7 to 10 days from the start of symptoms. Just wait for at least 10 days to give your body a chance to heal your virus before pressuring for unneeded antibiotics.
Antibiotics are not innocuous. They have toxicities and side effects. This means that antibiotics not only do no good in a viral infection, they can actually harm the patient. This is at odds with a fundamental precept of medicine: "First, do no harm."

What is an example of direct evidence for evolution is... genetic changes in plants antibiotic resistance in bacteria pesticide resistance in insects or all of the above?
genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects.
Which biological agent may be susceptible to antibiotic's but can develope resistance?
bacteria
How could you explain the increase of infection in hospitals by antibiotic-resistance bacterial?
Bacteria become resitant to antibiotics by evolution .
What is an explanation of how antibiotic resistance occurs?
Bacterial resistances are developed due to mutations that are passed down from generations of bacteria. Antibiotics generally kill all but the strongest bacteria or bacteria that have resistances to these antibiotics, resulting in only these bacteria reproducing, passing on the antibiotic resistances to future generations. Over time, entire populations of bacteria can develop a resistance to an antibiotic if they are frequently exposed to it.

Why do bacteria have extra chromosomal DNA?
Extra chromosomal DNA - plasmids- are useful to bacteria as they possess favourable genes conferring resistance to certain toxins/antibiotics and/or assist with the survival of the bacteria through metabolic benefits. The extra chromosomal DNA is only maintained if it has a purpose so a plasmid conferring antibiotic resistance will not be maintained by a bacterium in an antibiotic free environment...
How is antibiotic resistance an adaptation?
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
Why does antibiotic resistance evolve in bacteria?
A random mutation in one bacteria can result in this. think of a huge population of bacteria. billions of bacteria. and only 5 or so have the resistance by a random chance (random mutation). the antiobiotics will kill all of bacteria, except for the 5 with the resistance. Then, only those 5 will reproduce. since they reproduce asexually, this resistance will be passed on to all of the daughter. Then, all of sudden, there are a lot of bacteria around that are resistant to the antibiotic... it can also occur by conjugation, which is when a bacteria inserts its DNA into another bacteria. this can result in the second bacteria having the resistance too. this is a very basic description of the process.
When bacteria are not affected by antibiotics they have?
They have resistance to the antibiotic.
Who benefits from a mutation that causes antibiotic resistance in bacteria?
The bacteria benefits.
Antibiotic in gene cloning?
If antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all non-transformed bacteria, that don't have the antibiotic resistance. There is a chance that the non-transformed bacteria can mutate to develop antibiotic resistance.
What is an example of direct evidence for evolution is... genetic changes in plants antibiotic resistance in bacteria pesticide resistance in insects or all of the above?
genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects.
Which biological agent may be susceptible to antibiotic's but can develope resistance?
bacteria
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 a word meaning a bacteria has adapted to antibiotics?
Resistant or resistance is when a bacteria has adapted to an antibiotic.
Has antibiotic resistance affected endocarditis?
Unfortunately, in recent years, the treatment of endocarditis has become more complicated as a result of antibiotic resistance
How does a population of bacteria resistant to antibiotics?
the bacteria mutates , so the antibiotic no longer affects the bacteria , therefore making it resistance
What contributes to the spread of antibiotic resistance among pathogenic bacteria?
Directional Selection
