Antibiotics are substances are obtained from bacteria and fungi. Antibiotics are used for many different purposes. The most important of these uses is as drugs to fight various diseases caused by harmful microorganisms. use of antibiotics has now made it possible to treat many diseases that were fatal prior to development of antibiotics. A few are used to treat certain cancers.
Antibiotics cure diseases by their property of being selectively toxic to microorganisms. When administered to a patient, they damage certain types of cells in the patient's body, but do not damage others. Antibiotics used as medicines are harmful to the cells of disease-causing microorganisms, but not normally not harmful for the normal body cells. Such antibiotics are used to treat a variety of bacterial diseases. A small number of antibiotics, have also been developed to attack human cells for treatment of cancer. They are able to cure cancer by only damaging cells that are in the process of dividing.
Antibiotics are also used to treat infectious diseases in animals and to control bacteria and fungi that damage fruit and grain. Sometimes small amounts of antibiotics are added to livestock feed to stimulate the animals' growth. Small quantities of antibiotics are also used as food preservatives.
Likely the biggest advantage of antibiotics, in terms of their use to treat disease, is that they can help the body fight off infections or other bacterial issues that the body will struggle to deal with on its own. They can be administered in a variety of ways, orally, intravenously as well as topically with the use of creams or even eye drops. They are relatively inexpensive to produce and come in natural, semi synthetic and synthetic varieties, and many of them have different uses depending on their strength and makeup.
There are a huge variety of antibiotics as medical science now has to search for new ways to use them in order to combat some of the new resistant strains of various bacteria. They still have an enormously wide application.
