Antibiotics were designed to kill bacterium that infect us. Unfortunately, they are indiscriminate and also kill the good bacterium that are mostly found in the large intestinal tract. This leaves a person open to reinfection, or other more prevalent infections, during and after use.
he discovery of antibiotics has been one of the most important reasons of fall in mortality rates. It was the effect of antibiotics and vaccines that actually raised the life expectancy, allowed people to have smaller families and in more ways than one, changed the way we live. It is time we know some basics of antibiotics, so that we are aware of their potential as well as limitations, and avoid blind self medication
Antibiotics, along with vaccines, are the primary reason for the fall in death rate during the last century. Thanks to the efficacy of modern antibiotics, bacterial infections and epidemics, which had always been the greatest scourge of human civilization, have today been reduced to a far less common cause of human mortality and morbidity. Antibiotics : an overviewAntibiotics are substances, which in very small quantities, can kill bacteria without damaging human cells. They do not affect virus or fungus and are usually not effective against other parasites like those causing Malaria and Amoebiosis. Thus their use is limited to bacterial infections.

These broad spectrum antibiotics can be effective in multiple infections, but that does not necessarily make them the treatment of choice in every infection. For most...
