Why are antibiotics not given unless a serious infection?
Bacteria can become immune to antibiotics and the antibiotics will not work in the future when you need them. They only work against bacteria and cold and flu are caused by viruses.
Can the same treatment be used for all bacterial infections?
Bacterial infections respond to different antibiotics. The doctor should do a culture and sensitivity test to see what the bacteria is and what antibiotics will work the best. Sometimes broad-spectrum antibiotics are given. This is a "shotgun" approach while using the antibiotic best suited is the "BB" gun approach. The shotgun approach will produce resistance forms of bacteria and are not the best idea.
How do microogarnisms avoid being attacked by antibiotics?
They don't. They develop a resistance to it. Just like people, each bacteria is slightly different even from bacteria of the same type. Some are slightly more resistant to a given drug than others. What happens is that when someone is given antibiotics and the drugs are not enough to kill all the bacteria only those that are most resistant to that drug remain. Even worse is when someone decides they feel better and stop taking their antibiotics. Then the bacteria split and/or share their genes with other bacteria and as a result that resistance is passed on to future generations.
Why is it important for a physician to know the exact identity of the bacteria involved in an infection?
It is important for a physician to know the exact identity of the bacteria in an infection because they need to know which antibiotic to give. If the patient is given the wrong medication, then the bacteria may become immune or the antibiotics might kill the 'good' bacteria.
When are antibiotics usually given?
Antibiotics are usually given to someone who is sick with an infection. There are many types of antibiotics.
What causes antibiotic-associated colitis?
When antibiotics are given, most of the resident bacteria are killed. With fewer bacteria to compete with, the normally harmless Clostridia difficile grow rapidly and produce toxins.
Why is antibiotics given for bacteria and not virus infection?
Simply because antibiotics only kill bacteria, and not viruses. There are no medications to kill viruses, your body has to fight the virus off on its own. There are some antiviral medications, but they do not kill the virus, they only prevent its growth, and only for very specific strains of very specific viruses.
Why do scientists have to find a new antibiotic to kill bacteria?
After releasing enough of one type of antibiotic onto some bacteria, given enough time the bacteria will adapt, and even change to be unaffected by the given antibiotic. The only way to inhibit the bacteria then is find a new, better antibiotic, after which, given enough time and exposure, the bacteria will get used to this antibiotic, so there is again a need for a new one.
What is the recovery rate for patients with neurologic complications of Lyme disease?
Most patients with neurologic complications of Lyme disease recover completely following treatment with antibiotics. Those who do not respond are usually given an additional course of antibiotics
In what ways can antibiotics be given to you in?
antibiotics are given because they help fight diseases
Why do some bacteria survive after anti biotic is given?
Basically when antiobiotic is given to patients, some bacteria change to overcome the effects of the antibiotic, and because of this, some bacteria change and mutate. Due to that those some will have genes that can withstand the effects of that particular antibiotic and than these bacteria have and advantage over the non resisant strains and they gradually survive and reproduce, they pass they genes onto their offspring. One reason is that some patients stop taking the antibiotics when they start to feel better. You should always take all of the antibiotics prescripted to you. If you stop taking the antibiotics too early, the weakest bacteria have died but the strongest ones will survive and reproduce.
Antibiotics are used to treat viral infections like the flu True or False?
Antibiotics kill bacteria. Antivirals kill viruses. However, a patient with a viral infection might sometimes be given antibiotics to reduce the work the patient's defenses have to do or to stop opportunistic infections.
