Antibiotics inhibit the growth of bacteria, fungus vand parasites. In the beginning, the antibiotics were isolated from living organisms. For example, penicillin was isolated from the fungus penicillium and streptomycin from the bacteria Streptomyces. The more modern antibiotics are being chemically synthesised. There are few or no side effects from antibiotcs and at the same time they are highly effective. The antibiotics to be used a particular infection depends on three factors: the location of the infection in the body, the ability of the antibiotic to reach the site of infection and its effectiveness in overcoming the infection. An antibiotic can cure the infection in two ways. It can directly destroy the bacteria causing the infection or it can prevent the bacteria from multiplying further. The antibiotics can be administered topically, orally or intravenously. They are administered topically in the case of eye or skin infections. In case of a serve infection the antibiotics are administered intravenously.
