Extracts from this essay...

Introduction

Antibiotics Introduction (1) Antibiotics are chemical compounds used to kill or inhibit the growth of infectious organisms. Antibiotic refers generally to antibacterials. All antibiotics share the property of selective toxicity: They are more toxic to an invading organism than they are to an animal or human host. Penicillin is the most well known antibiotic and has been used to fight many infectious diseases, including syphilis, gonorrhea, tetanus, and scarlet fever. Another antibiotic, streptomycin, has been used to combat tuberculosis. Against The main problem scientists have come across where antibiotics are concerned is antibiotic resistance. (2) This is due to the large amount of antibiotics consumed by the nation as a whole. Many people believe that antibiotics are the answer to all illnesses such as the common cold or flu.

Middle

* Bacteriostatic - which limit the population growth. And so if a course is not finished in the case of the use of bacteriostatic antibiotics there are still live bacteria, which exist, these can then go on to reproduce asexually. The daughter cells would then have immunity to the antibiotic used. New types of antibiotics have to be manufactured all the time. This is not only time consuming but money wasting also. (5) Mutant bacteria are a problem as they can be immune to many antibiotics making it even harder to find a cure for a specific strain of infection. There are other problems which could arise are that allergies may develop mainly with the high usage of penicillin. Not all antibiotics simply cure bacterial infections but they can also cause side effects such as diarrhoea, lightheadness, headaches, vomiting and stomach discomfort.

Conclusion

Perhaps one of the most important and useful uses of antibiotics is there help in chemotherapy and in helping to cure leprosy by combining with other antibiotics. Although there are many reasons as to why antibiotics are bad for us when used correctly they are a great advantage and save many lives. (4) "My infection wouldn't go away after several days, I gave up and took antibiotics - there was a huge improvement straight away' said Dr. Rubinstein. Antibiotics provide relief from infections such as: * Ear infections * Acne * Arthritis (in some cases) * Sinus infections * Some lung infections * Bladder infection * Infections of the blood stream etc (4) Antibiotics are chemicals that kill bacteria but not human cells. They work by interfering with metabolic pathways that are unique to bacteria or different enough from humans that they are not toxic. They kill bacteria indiscriminately and thus will kill pathogens. So when used properly antibiotics are a huge advantage.
