How Antibiotics Work
Sometimes your immune system is not able to activate itself quickly enough to outpace the reproductive rate of a certain bacteria, or the bacteria is producing a toxin so quickly that it will cause permanent damage before the immune system can eliminate the bacteria. In these cases it would be nice to help the immune system by killing the offending bacteria directly.

Antibiotics work on bacterial infections. Antibiotics are chemicals that kill the bacteria cells but do not affect the cells that make up your body. For example, many antibiotics interrupt the machinery inside bacterial cells that builds the cell wall. Human cells do not contain this machinery, so they are unaffected. Different antibiotics work on different parts of bacterial machinery, so each one is more or less effective on specific types of bacteria. You can see that, because a virus is not alive, antibiotics have no effect on a virus.

One problem with antibiotics is that they lose effectiveness over time. If you take an antibiotic it will normally kill all of the bacteria it targets over the course of a week or 10 days. You will feel better very quickly (in just a day or two) because the antibiotic kills the majority of the targeted bacteria very quickly. However, on occasion one of the bacterial offspring will contain a mutation that is able to survive the specific antibiotic. This bacteria will then reproduce and the whole disease mutates. Eventually the new strain is infecting everyone and the old antibiotic has no effect on it. This process has become more and more of a problem over time and has become a significant concern in the medical community.
nside your body there is an amazing protection mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body. To understand the power of the immune system, all that you have to do is look at what happens to anything once it dies. That sounds gross, but it does show you something very important about your immune system.

When something dies, its immune system (along with everything else) shuts down. In a matter of hours, the body is invaded by all sorts of bacteria, microbes, parasites... None of these things are able to get in when your immune system is working, but the moment your immune system stops the door is wide open. Once you die it only takes a few weeks for these organisms to completely dismantle your body and carry it away, until all that's left is a skeleton. Obviously your immune system is doing something amazing to keep all of that dismantling from happening when you are alive.

The immune system is complex, intricate and interesting. And there are at least two good reasons for you to know more about it. First, it is just plain fascinating to understand where things like fevers, hives, inflammation, etc., come from when they happen inside your own body. You also hear a lot about the immune system in the news as new parts of it are understood and new drugs come on the market -- knowing about the immune system makes these news stories understandable. In this article, we will take a look at how your immune system works so that you can understand what it is doing for you each day, as well as what it is not.

Antibodies and antibiotics are not the same thing...

Antibodies are made by the cells to counteract and tag invaders. According to Harpers Biochemistry, they are a glycoprotein structure which means they are made from both protein and specific sugars.

The structures define their function. For example, an antibody will be manufactured specifically to attach to a specific virus. If a virus mutates, the immune system will need to change the structure of the antibody to match.

Antibodies are said to be a part of the humoral immune system because they exist freely in the circulatory system or are bound to cell membranes.

Antibodies can be a very powerful research tool, they can help us understand the functions of protiens in our bodies, for example one could raise a polyclonal antibody against a protein or fragment of that protein (even a section, via use of a peptide), this can then be used to track the native protein in the body and if one adds a stain one can see what it does and how that protein works, bit like placing a tag on it. Antbodies are used in a whole varity of research modles and can hel develop testing and diagnostic kits, such as the testing for BSC, in meats, Also towards development of cures. One can also attatch an agent that attacks the protein / body the antibody recognises, by coating it, this can then be used as an antibiotic, by coating the tail of the antibody, the stick bit on the (Y) the antibody then finds and attaches to the native protein and attacks. A lot of primary research is done on developing polyconal and Monoclonal antibodies in cancer studies and HIV studies, there usefulness is extensive.
