Chemotherapy said to be the treatment of infections by substances which destroy or suppress bacteria. The sulphaonamides were the first group of chemical drugs to be used successfully in the treatment of common infections. They exert their effect by inhibiting the growth if invading bacteria,thus allowing the defensive mechanism of the body to overcome susceptible organisms. Unfortunately the sulphonamides are ineffective against many dangerous bacteria.
The discovery of penicillin represented a major victory in the fight against bacteria,and greatly increases the range of bacteria which can be over come. Penicillin is not a chemical drug but is,in fact,the product of a living mould. It is called an antibiotic and destroys the germs directly. Several other potent antibiotics are now available. Streptomycin is the first agent to be effective against the tubercle bacillus, while chloramphenicol suppresses the typhoid group of bacteria. The tetracycline antibiotics have further extended the scope of chemotherapy. One great difficulty has arisen in the use of antibiotics; in some cases bacteria at first susceptible to a particular antibiotic later become resistant yo it. For example ,nowadays staphylococci grown from hospital dust are nearly always resistant to penicillin.
There may be more explanation from every individuals also .
