second line is white blood cells or leucocytes and third is the specific immune response which employs immunoglobulin’s or antibodies. Without this three line of defense man would have not been able to survive against the pathogens which are present around us in millions and billion numbers. Therefore immune system is essential for our health.
Antibiotics work to destroy bacteria. Bacteria are single-cell organisms. If parasites make it past our natural defenses and start reproducing inside our bodies. We want to destroy the bacteria to eliminate the condition. It has been selected so that it will destroy the preferred bacteria but not the tissues in your human body.
Everyone has his/her own perception and views regarding this topic and issue.I have little information which i would like to share with this forum.It is an unfortunate fact that though antibiotics are being used constantly but now bacteria have developed resistance against these drugs. It is a very natural process that new antibiotics with more effectiveness are being developed and bacterial genome is revolutionizing against these newly synthesized antibiotics.
In response to the poster who asked why antibiotics are prescribed for viral infections, the answer has to do with preventing a bacterial infection. Some viral infections, such as flu, can make the host highly susceptible to certain bacterial infections like pneumonia. In fact, during the 1918 Spanish Flu pandemic, many if the victims died from secondary bacterial pneumonia, not from the influenza virus. The symptoms caused by the flu virus provide a good environment for the bacteria to multiply rapidly, and can also weaken the hosts’ immune system, thus allowing for increased bacterial growth. When a patient has certain types of viral infections, antibiotics can help prevent these very serious bacterial infections.
Antibiotics are also used as a preventative medicine in patients with other types of diseases. For example, some antibiotics may be used in cancer patients. Cancer itself does not necessarily shut off the immune system, as the original poster stated. Rather, the treatments used for cancer, chemotherapy and radiation, target rapidly multiplying cells, including those involved in fighting infections. These therapies leave the patient more susceptible to infection.
As with all medications, it is important to use antibiotics only as prescribed by a licensed medical practitioner. Overuse and improper use of antibiotics can cause many problems, including the development of resistant populations. Because antibiotics have been used improperly, many drug-resistant strains are developing. For example, tuberculosis is one of the leading causes of death to infectious disease world-wide. Tuberculosis is caused by the bacterium M. tuberculosis. This bacterium is very difficult to treat, and requires extremely long treatment with antibiotics, often months or more. In areas where it is difficult to get treatments, patients only take the antibiotics for a short time. The bacteria are not all killed off, and the surviving bacteria can develop resistance to the antibiotic. As they multiply, they become the predominant strain of bacteria in the host. These resistant bacteria can then go on to infect other people. Now, there are even strains of M. tuberculsosi that are resistant to all available antibiotics. Properly using antibiotics in patients with susceptible strains is necessary to help minimize the spread of this very dangerous pathogen.

An antibiotic always gives as a course and the patient should complete the course to get the effect of the antibiotics. It is not advisable to take the antibiotics without the prescription of the doctor.
The US National Library of Medicine1 says that antibiotics - powerful medicines that fight bacterial infections - can save lives when used properly. Antibiotics either stop bacteria from reproducing or kill them. "Your body's natural defenses can usually take it from there."
Before bacteria can multiply and cause symptoms, the body's immune system can usually destroy them. We have special white blood cells that attack harmful bacteria. Even if symptoms do occur, our immune system can usually cope and fight off the infection. There are occasions, however, when it is all too much and some help is needed.....from antibiotics.
Alexander Fleming discovered penicillin, the first natural antibiotic, in 1928.
The first antibiotic was penicillin. Such penicillin-related antibiotics as ampicillin, amoxicillin and benzylpenicilllin are widely used today to treat a variety of infections - these antibiotics have been around for a long time.
There are several different types of modern antibiotics and they are only available with a doctor's prescription in most countries.
Overusing antibiotics - There is concern worldwide that antibiotics are being overused. Antibiotic overuse is one of the factors that contributes towards the growing number of bacterial infections which are becoming resistant to antibacterial medications.
Antibiotics fight against bacterial infections, they are not anti-viral. Taking antibiotics knowingly for viral infections is likely a mistake. Some doctors just prescribe it because without doing couple of tests it is hard to tell whether or not the infection is viral or bacterial.
