Antibiotics     An antibiotic drug, is be to be a drug produced by certain microbes.Most doctors white plague antibiotics to help fight the germs in a patient. Antibioticsare obtained from plants, kingdom Fungi, air, water, soil, just just about anything on earth.Antibiotics kill and attack the germ or virus in the body, but do non hurt thehuman carrells, ordinarily. The antibiotics are utilize to treat many various types ofdiseases, such as tuberculosis, syphilis, and several kinds of infections.      sight piss been using antibiotics for more than 2,500 years. They usedmolds to help cure some skin infections and rashes. It was in the late 1800sthat the real study of medicine began. Louis Pasteur find that bacteriumwas the cause of disease, and proved wrong the theory of spontaneous generation. aft(prenominal) him there was Robert Koch, who developed a method of isolating and growingbacteria. Scientists try developing drugs that c ould kill microbes, but theyproved to be either desperate or ineffective.     In 1928 there was a discovery by horse parsley Fleming. He detected that a inwardness he called "penicillin" destroyed bacteria. so in the late 1930s,two British scientists invented a method of extracting penicillin from the mold.This was the starting time of developing new drugs to treat diseases and bacteria.     Over the years, numerous thousands of antibiotic sensible sacrifice beenfound in nature as well as produced chemicly but, there are few that are safeand useful. nevertheless the wizs that are safe and effective have saved many livesand have helped extend life expectancy.     Right now, there is more than 70 contrasting kinds of antibiotics in use.Most antibiotics are used to treat infections, some for fungi and protozoa, butantibiotics are not usually effective against viruses. So they have developedother methods such a s vaccines against viruses.     Antibiotics work by one of three ways, they can one, prevent the cellwall from growing two, jampack the cell membrane or three disrupt thechemical processes. When the antibiotic prevents the cell wall from forming, theantitoxin surrounds the bacterias membrane, and then it forms a rigid wall that kale the cell wall from splitting open, which would produce another cell. Thehumans cells are not hurt by this because human cells do not have cell walls.     If the antibiotic obstructs the cell membrane, which controls the flowof items in and out of the cell, then inborn nourishment can escape the cell.Then a toxic substance could enter the cell killing it. Human cells are not completed by this method because the antitoxin only effects the microbial cells.     If the antitoxin disrupted the chemical process, then the microbe cannot
