How do anti biotics work?

will they make the anti bodies and white blood cells less effective
Answer:
Antibiotics divide into 2 groups, bactericidal- these damage the bacteria for example by destroying their outer protective coat allowing the white cells to phagocytose them. Bacteriostatic-these prevent replication allowing the white blood cells more time to mop them up.

This answers half of the second part of your question. There is some evidence that early use of antibiotics means that antibodies to the organism are never formed.

This means that an individual that has faced an organism before, without antibiotics, already has the antibody to it and responds and destroys the organism much faster than someone who previously received an antibiotic.
they attack the germ in your body that is making you sick
Not really. Our antibodies and the body's natural defenses work only at a certain level, however, when the microorganisms increase greatly in number, our body could not cope on its own, that's why we need to take antibiotics. But we should consult a doctor before taking any antibiotic to make sure that we don't get overdosed or underdosed. Underdosage is equally harmful because the microorganisms could become resistant to that certain antibiotic.
No antibiotics inhibit the growth of bacteria. It's kind of like soap. but for your insides haha. They basically fight bacterial infections, but not viral infections. like the flu or colds.
"Antibiotics work to kill bacteria. Bacteria are single-cell organisms. If bacteria make it past our immune systems and start reproducing inside our bodies, they cause disease. We want to kill the bacteria to eliminate the disease.

An antibiotic is a selective poison. It has been chosen so that it will kill the desired bacteria, but not the cells in your body. Each different type of antibiotic affects different bacteria in different ways. For example, an antibiotic might inhibit a bacterium's ability to turn glucose into energy, or its ability to construct its cell wall. When this happens, the bacterium dies instead of reproducing. At the same time, the antibiotic acts only on the bacterium's cell-wall-building mechanism, not on a normal cell's.

Antibiotics do not work on viruses because viruses are not alive. A bacterium is a living, reproducing lifeform. A virus is just a piece of DNA (or RNA). A virus injects its DNA into a living cell and has that cell reproduce more of the viral DNA. With a virus there is nothing to "kill," so antibiotics don't work on it."

So in answer to your question, will they affect the antibodies and white blood cells, then no, as he antobiotic only attacks the bacteria present in the body.
no they will help the white blood cells which are battling the infection and not winning, they will have the correct "code" to eradicate the ilness or virus and hopefully the white blood cells will take a copy of this for the future should the disease or virus return.
