The first line of defense is the skin, or epithelium; anti-microbial chemicals in the tears and saliva; mucus and cilia in the nose and throat; the formation of scabs after getting a cut. The second line of defense is the immune system, including interferons, antibodies, lymph nodes, and various white blood cells.

Which is one way that skin helps protect the body from infection?
All skin naturally has bacteria, and when in the right level of abundance this isn't an issue and is in fact quite beneficial to survival. The problem comes when we have over population of bacterial colonies upon or skin, specifically harmful ones. In these cases the acidic pH of the skin can act as a defence mechanism as well as other bacterial colonies that secrete chemicals which prevent harmful bacteria from flourishing. It must also be understood that the skin itself is a defence mechanism against pathogenic (disease causing) bacteria from entering into the body where they can cause more harm, Its acts as a thick strong barrier (which is very difficult to penetrate when your only a single cell !).
Is bacterial endosporulation a reproductive mechanism?
No. Endosporulation is the process where bacteria encapsulates itself within an endospore - it's a form of protection against an extreme range environmental stressors. Sporulation on the other hand is the act of producing spores of the bacteria, and that IS a reproductive mechanism.
What is peyer's patch?

Yes
Do antibiotics work against bacteria?
antibiotics are useful against bacteria because they help to kill off the nasty bacteria or they can also stop the bacteria from reproducing - so the illness doesn't get worse. this then gives your body time to make antibodies which will eventually distroy the bacteria. after this, you won't get the disease again because you are immune to it.
Why does an antibiotic not work the same for all bacteria?
Bacteria also do evolve. If one bacteria is mutated, and survives an attack by antibiotic, he multiplies and forms more bacteria which are more resistant against antibiotic. As days of surviving antibiotics and multiplying eventually creates a bacteria which is resistant against it.
What does antibactrial mean?
Active against bacteria.
What is the bodys first defense against bacteria and viruses?
Lysozymes
What are the positive and negative aspects about bacteria?
