Pathogenic bacteria are microorganisms that contribute to development of bacterial diseases. There are infectious diseases well known in the historical context that caused epidemics, such as plague, smallpox, cholera, typhoid, and typhus (Wassenaar, 2009). In order to prevent or cure diseases the special medications are used which are known as antibiotics. Antibiotics are chemicals that kill, injure or inhibit the growth of pathogenic bacteria. Consumption pick of anitibiotics started with discovery of Penicillin which played significant role in the pharmaceutics. According to American Chemical Society (2004) the one of the greatest discoveries is the discovery of the Penicillin. Before the existence of antibiotics people were dying in the hospitals just from the pathogenic bacteria in their wounds.
The history of using Penicillin as a medication begins in ancient times when Egyptians were putting bread with molds on bleeding wounds. However, it is assumed that the discovery of the penicillin as antibiotic belongs to Alexander Fleming in 1928. American Chemical Society (2004) states that Alexander Fleming was examining petri dishes with the colonies of pathogenic bacteria when saw the unusual thing: in the petri dish contaminated with mold bacteria were not growing at all. As a result, the work of separation of the substance that was killing different bacteria began, but was not successful.
The experiments failed by Fleming were continued in 1939 by Howard Florey, Ernst Chain, and their colleagues at Oxford University. Due to the war it was difficult for scientists to perform experiments of purifying Penicillin, while hospitals which were overfilled with patients needed medicine which will cure all bacterial diseases. In 1940 F...

...er to cure the particular bacterial diseases the cocktail of different antibiotics is being used, but even this is not effective enough. The main goal of present pharmaceutical companies is to find a drug which would be as effective as penicillin was in 1940’s.

The Factor of War in the Development of Penicillin The discovery, development and subsequent use of penicillin can be considered to be one of the most important breakthroughs in medical history. There were many factors, which were involved in the development of penicillin, and it could be argued that war was the most important, but other factors were also responsible. Alexander Fleming was working in London as a bacteriologist in 1928 when he noticed that a growth of a mould called penicillin produced a substance that actually killed the germs he was working on. He realised that this might be very important and a year later he wrote an article about his findings. However, Fleming did not have the facilities or the support to develop and test his idea that penicillin could fight infection, and he didn't develop it further.

Years later other scientists were also intrigued by the possibilities of penicillin and produced enough penicillin to prove that it was a useable antibiotic. The scientists from Great Britain were developing all of this during World War II, and unfortunately funding for their drug was unavailable due to the war. They decided to bring their concepts to the United States, and once enough was made, it was eventually used, to treat wounded soldiers during World War I.
“Antibiotics" is the name given to the group of chemicals, particularly in medicine, that stop or inhibit the growth of, microorganisms such as fungi, bacteria, and parasites, or that kill the microorganism. They are, however, completely ineffective against viruses. There are two kinds of antibiotics, namely; bactericides, which interfere with the cell wall or contents of the bacteria, thereby killing it, and bacteriostatics, which prevent the bacteria from reproducing. They are used to treat bacterial infections in humans and animals. Bacteria are microorganisms consisting of single cells, and reproduce by mitosis. They usually live in colonies. Some bacteria and other microorganisms produce antibiotics to kill off other species, making more resources available for the organism making the chemicals. Ironically, it was this that led to the discovery of antibiotics in 1928, when Alexander Fleming noticed that the fungus Penicillium notatum, which had contaminated a sample of pathogenic bacteria, had killed the bacterial colonies in a petri dish.
18). Even though those diseases were not his goal to cure it still made penicillin revolutionary for the time being. Fleming now knew how to make penicillin and started to mass produce it. In the 1930s during the upgrading process of penicillin Fleming himself was cured of severe conjunctivitis. Then in the 1940s the fully developed penicillin was created. The creation of penicillin cured a wide variety of diseases, which led to the world excelling in growth, and penicillin improved the way of medicine at the time. The variety of diseases cured by penicillin made it a must have antibiotic. Penicillin was used to cure multiple diseases including syphilis, gonorrhea, tuberculosis, gangrene, pneumonia, diphtheria, and scarlet fever ( Common Antibiotics ). All the diseases have one thing in common, they all have the ability to spread, some faster than others. When a disease is discovered people tried to make a cure. When penicillin was made diseases that were thought to never have a cure were cured. People began to demand that penicillin be sold in local pharmacies. Penicillin was released to help people with the variety of diseases curable by
Throughout history disease has run rampant taking many lives with every passing day. Finding a cure or even just a tool in the battle has been the main focus of scientist throughout time. This focus is what brought us the discovery of antibiotics. Over the years antibiotics have been misused by patients, over prescribed by physicians and have led to resistant strains of bacteria.
Doctors are trying to figure out how to kill these harmful bacteria’s. But it is getting harder to discover other antibiotics.

Compounding all of these solutions, the pharmaceutical industry needs to conduct extensive research on developing new antibiotics for various pathogenic bacteria by studying the bacterial structure. This will help scientists to formulate ways of counteracting the functions of the various constituents of bacteria.
Penicillin, derived from the mold Penicillium, is the first antibiotic to successfully treat bacterial infections on humans. It was accidentally discovered by scientist, Alexander Fleming. While Fleming was growing Staphylococcus, a serious and often deadly infection, in a dish, he noticed the bacteria had stopped growing after a mold found its way
Over the years humans have tried every possibility to overcome the health problems, spread of epidemics and infections, disease control and have worked towards a healthy society free of disease and health problems. They have succeeded to a great extent. The book “Good germs, bad germs” describes that though the life expectancy is now far more as it was in previous eras. Epidemic problems and infectious diseases are now getting lesser and lesser and humans are being treated successfully. The hygienic conditions have also been improved so as to ensure least growth of microbes, germs, parasites and bacteria. Antibiotics have been invented to address diseases and infections caused by bacteria and viruses. With all these substantial efforts the biologists, physicians and scientists have triggered another epidemic which is even more severe. They have killed those microbes and bacterial species which were human friendly and as a result of either their disruption or mutation, pathogenic bacteria have even become more active and resistant to treatments. This has led to increased ineffectiveness of antibiotic drugs, low immunity and various infections and inflammatory diseases. The chlorinated water for drinking and food processing along with excessive hygienic conditions indicates our fight against these bacteria and germs. Further, these antibiotics are even given to the livestock which becomes our food and as result many of their resistant germs end up in our digestive tract and other organs. Thus, the war against microbes through excessive cleanliness and use of antibiotics has resulted in antibiotic resistance among humans, which has become one of the prominent problems of medical science

Thesis: With the advent of antibiotics in 1929 Fleming said, "The time may come when penicillin can be bought by anyone in the shops.Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant."With the overuse of antibiotics today we have seen this very idea come to be.Over usage is caused most prevalently by a lack of education on the part of the patient.Thus stated, the way to overcome such a circumstance is to educate, not only the patient but also the physician.
The discovery of antibiotics is attributed to Alexander Fleming who discovered the first antibiotic to be commercially used (Penicillin) in approximately 1928. An antibiotic, also known as an antimicrobial, is a medication that is taken in order to either destroy or slow the growth rate of bacteria. Antibiotics are integral to the success of many medical practises, such as; surgical procedures, organ transplants, the treatment of cancer and the treatment of the critically ill. (Ramanan Laxminarayan, 2013)
Bacteria are found nearly everywhere within the body and most types are harmless or even helpful to bodily function (Novitt-Moreno). While it is important to have these bacteria in the body, pathogenic invaders can cause serious illnesses. Pathogenic bacteria work by either actually attacking a part of the victim’s body or releasing toxic waste products into the body. Bacteria are single-celled and contain all of the cellular mechanisms needed to live, grow, and reproduce (Novitt-Moreno). That means, when treating a bacterial infection, it is critical to have a highly specific antibiotic that can destroy the unwanted
The term “microbiology” refers to the branch of study that deals with microorganisms. Microbiology is extremely important in today’s time for the crucial information that the study provides. Human’s have had a long and cruel history of disease and sickness, for example the bubonic plague, but microbiology gives scientists the ability to observe, study, and prevent sickness like the bubonic plague to ever happen again. At the center of microbiology lies the bacterial cell, one that differs from those of a plant or animal because it lacks a nucleus and membrane-bound organelles which, in turn are traded for pili, flagella, and in some cases a cell capsule. Bacteria that are capable of causing illness or disease are called pathogens, pathogens work by releasing toxins in the body or directly damaging the host’s cells. An article by Lise Wilkinson explains that the earliest categorizations of bacterial cells first occurred in the late eighteen-hundreds to the early nineteen-hundreds by scientists (at the time) O. Muller and C. Ehrenburg (Wilkinson, 2004). The observation and identification of unknown bacteria that emerge is crucial because these new bacteria might be pathogenic and cause illness so it is very important that the bacteria is identified as soon as possible in order to either prevent the upcoming illness or treat it. While the common person is unable to identify if they are carrying bacteria (which is very likely), specialized tests that are ran in a lab can identify different types of bacteria and can even help
