Essay on Antibiotics
Let's begin with the definition of antibiotics: "Antibiotics are chemical substance
made from a mold that can kill bacteria and bacterial infections" (Miller, 2010)
In 1920 Alexander Fleming invented Penicillin by having some bacteria on dishes
and he left them dirty. After a while Fleming noticed that the bacteria had mold on it and
then he realized that it killed the bacteria on the dish. He was surprised by that so he
examined it. Fleming found what the mold was and it was Penicillium so Fleming took it
apart and he found the bacteria killing chemicals which are known as Penicillin.
("Antibiotics", 2010). No one cared about what Fleming discovered until two chemists
Howard Florey and Ernst Chain continued Flemings search and improved it, and made
purified form of Penicillin and named it antibiotics. These three chemists got a noble
prize in 1945. . ("Antibiotics", 2010). So what is penicillin? It is any of various
antibiotics obtained from molds and uses in the treatment of infections and diseases".
(Miller, 2010)
The advantages of antibiotics are: that nowadays people and doctors are
recommending antibiotics because they cure faster. Another advantage is: it can cure
bacteria such as tuberculosis, impetigo, syphilis, and fungus. There are also Broad-
Spectrum types of antibiotics which work equally well on infections. There are over a
100 types of antibiotics. If the right antibiotic is taken and approved from a doctor, it will
cure the disease in the shortest period of time. (Raf, 2009)
After I gave an idea about the advantages of antibiotics now I will reveal some of
the disadvantages of antibiotics. The common and crucial side – effects of antibiotics are:

Essay on Antibiotics
Stomach ache, diarrhea, vomiting, rash, dizziness, and cramps. So I urge any patient that has any
of these side effects, they must see their advisers or doctors.
If you take antibiotics repeatedly it is very harmful and may cause Cancer.
Sometimes doctors don't know about the bug which caused the infection. So doctors
prescribe Broad Spectrum antibiotics, which kill healthy and unhealthy bacteria in the
body. That’s why it's not good to take antibiotics fluently or by yourself. To take
antibiotics you need a prescription from your doctor, and please follow the doctor's
advice.
You have to know that when you take Broad Spectrum antibiotics there are some side-
effects: they reduce the level of calcium, iron, magnesium and can also cause psoriasis.
So I conclude that after considering all the advantages and disadvantages, we can clearly state
that the overuse of antibiotics drugs is harmful for us. Medicines are good for us as long they are
used when only needed. (Raf, 2009)
Antibiotics work in both ways: A) "With a bacterial antibiotic which kills the bacteria, it
usually joins in with the arrangement of the bacteria's cell wall or its cell contents. B) To
stop bacteria from multiplying". (Nordqvist, 2009)
Now I will give some of the famous antibiotics:
Penicillin: treatment for bacteria.
Bacitracin: it is used for skin and eye infections.
Streptomycin: antibiotic produced by the same genes.

Erythromycins: it is most effective against gram-positive bacteria. ("Types of Antibiotics’’,
2007)
All these antibiotics end with cillin because they are a compound of penicillin and
another chemical.
Antibiotics: How do they affect society?
Economically speaking the immediate profit of antibiotic is: linked with the use of
antibiotics within the manufacturing industries such as agriculture. This profit becomes higher
when there is a reduce deaths of animals and plants which is due from infection and higher
growth rates come in.
Short term profits: you will have good profit and you will not waste that much tools or
people and according to the companies that produce the treatment they will achieve a huge
profit. Long term profits: in the long term it is likely there will be decreasing profits as there is
more money spent on find a new generation of antibiotics which is suitable to kill the new type
of microbes which always renew and create new types. So I conclude that there will be a loss of
crops and money and if they find better antibiotics microbes will adapt with them and that's
causes loss of cash. (Levy, 1995)
Environmentally microbes are found everywhere in the environment. However, there are
many microbes which play a role in human affairs and in the environment.
Microbes have an effect on animals, plants, and human health, so it is needed to use antibiotics to
kill a bad bacterium which causes disease, death and stopping them of spreading around. (Levy,
1995)

Essay on Antibiotics
Politically and socially, the law which contributes to the growth of antibiotic resistance is
the difference between countries on prescription rights. In Canada antibiotics need to be
prescribed by doctors. While in many third world nations any citizen may purchase antibiotics
without a prescription easily. Here begins the danger, it is only a time before those resistance
microbes travel to other countries through immigration and travel. (Levy, 1995)
Culturally there the understanding of taking antibiotics varies between countries and people
In the west antibiotics are used as a last resort to tackle infection and sickness its used sparingly
and in set courses according to the Dr's advice.
Where as in different countries it is sold as over the counter drug and is m0isused which is very
bad to the population and will increase the strength of bugs by becoming super bug due to
mutation and development of antibiotic resistant bugs.
Ministries of health are aware of this misconceptions and are trying to spread more awareness
throughout people in those countries ( Dr. Aumier, 2010)
