What are the different types of Antibiotic drugs and why are they used?

Antibiotics either destroy the harmful bacteria causing infections in the human body or they help in stopping their reproduction. Generally, when harmful bacteria caused various infections and symptoms in a human body, the body's immune system destroys them. However, many times, when there are too many bacteria present that it exceeds the capability of the immunity system of the body, antibiotics are administered to destroy those bacteria.

Different types of antibiotics and their uses

In order to treat an infection by administering antibiotics, it is important to identify whether it is being caused by bacteria or viruses, as antibiotics can work only on bacteria, not on viruses. One can buy antibiotic drugs online or at various medical stores only against a prescription provided by a medical practitioner. Overuses or improper uses of antibiotics improves the immune system of bacteria against the antibiotics, and thus the antibiotics lose their effectiveness in treating infection caused by those bacteria. Some antibiotics can be used for the treatment of a wide range of infections, whereas there are other types of antibiotics which are effective against only a few bacteria.  In many cases, antibiotics might be administered with the intention of preventing any infection such as before different forms of surgeries.
