If all the bacteria on your body suddenly dissapeared, would it be fatal before you were re populated?

Maybe. I'd say yes, actually. Bacteria do a lot, and without them many of your essential body processes would be inefficient.\n\nAs far as I can tell, bacteria break down certain products. I'm not sure which, where, and how, but I'm fairly certain they do. I guess it depends on how quickly the bacteria were restored, but I'm fairly sure they're essential for survival.

Yes, darling. It is true. Once your brain is gone, it will stop growing and you eventually turn into worm food.

Most probably it will get infected. And if then you don't treat the infection on time you might lose that part of the body and even die. But it will take a few days or even weeks before it happens

Your heart stops beating.  Your synapses slow their firing until you are brain dead and no electrical current is flowing through the nervous system.  Your body will generally expel any waste matter (air, urine, feces) being held.  Sometime around this time, you will either discover that there is an afterlife of some sort, or you will blink into nothingness, with absolutely no consciousness to be aware of the fact that there is no afterlife.  The body will begin the approach to rigor mortise.  And bacteria will begin decomposing the body.  Years and years later, only ash (and perhaps fossilized bones) will be left of your body.  If there is an afterlife, you will never be able to tell anyone.  If there isn't, you will never be able to tell anyone.  Those who say they know the truth about the afterlife, either way, are not intellectually honest.  Which is why this question will continue to evoke philosophical debate ad infinitum.

Yes it does, it just takes a while for to get back to normal numbers.  That all depends on how fast the bacteria goes through its cycle of dividing to copy itself.

Some bacteria cells are naturally more or less resistant to bacteria - it's genetic variation just like some people are more resistant to the effects of alcohol.  When a population of bacteria is exposed to an antibiotic, some will die right away, while more naturally resistant bacteria will stay alive.  If there is not enough antibiotic to kill all the bacteria (like if someone doesn't take all the antibiotics prescribed to them), only the bacteria that were naturally more resistant will be left.  With little competition to keep them from replicating (because all those less resistant bacteria died), the remaining cells will reproduce to form an entire population of resistant bacteria.

your body will naturally refuse anything foreign. wait it will come out on its own.

probably puke your guts out.  it could also kill you.

Yes.  Did you have the MRSA before the surgery, or become infected after?  Some people are colonized with MRSA...meaning they carry it in their bodies and are not symptomatic until something else stresses the body.  Really need to ask your doc.  There are several web articles on this.  Just do a search.  Enter ,"MRSA, colonization" in the search bar.

It is an infction that came about because a person or people only took the first few doses of thier antibiotics - all that does is kill off the weaker bacteria, and allows the strongest to survive and thrive. Once the infection with this leftover strong bacteria gets full blown, antibiotics don't always work to destroy it. That is why you have to take ALL of your doses of antibiotics. This is becoming a world problem. In a lot of southeast asian countries, if people get sick, they can go buy antibiotics over the counter. They take them only until they 'feel better', which means that the bacteria is probably not gone, and that only the strongest are left to reproduce. Some bacteria like this adapts to the point where it actually feeds off the antibiotics, killing the host. The only way to take care of this problem is for basically the entire planet to keep careful control of antibiotics.  Some strains are becoming resistant because of this.

No, otherwise everyone would be dead!  God bless you is just a pleasantry.  If your heart stopped, even briefly, it would cause an arrhythmia and you would at the very least have severe chest pain or become unconscious every time you sneezed.

Even more so . That is what causes the body to decompose. If you died on Antarctica your body would be preserved as the germs would be frozen in their tracks

Humans would die of poisoning as the food biodegrades in your body because our body's are very intolerant to the bacteria feeding on the biodegradable material.  The bacteria and enzymes in our stomachs aids in killing the dangerous bacteria.\n\nReference the Gila Monster that does not excavate anything...  they are extremely poisonous because they do not digest.

Your body does create antibodies, but some bacteria miltiply very quickly and simply over-power the body's immune system, and then you would never get better, you may suffer permanent damage, and you could possibly die. \n\nAntibiotics work in one of two ways. Some actually kill the infection, and others only prevent the growth of the infection, thus giving the body the time it needs to fight the bacteria itself.

No, but you will probably get an infection around the bit that's left (like when you get a sliver under your skin)

The body begins to canabalize itself, starting with muscle tissue and then fat I believe.  Forty days is probably close to the limit for survival if not well beyond it.  Dehydration will kill much more quickly though, more like 3-4 days if I'm not mistaken.

Back up for life, If you dont mean bringing some one back to life the answer is NO but,\n\nour body or any other living organism will have life support tools that backup and try to prevent massive disaster to life.\n\none such example is your immune system.\n\nand there is a backup mechanism for the heart in case of blocks Heart tries to by pass the blood flow so as to minimise the risk. and only when it is beyond control one gets a cardiac arrest.
