Recommended: First chapter on microbiology

Although many people do not know about microbiology, the scientific developments within this area are used in everyday life. Microbiology is the study of microorganisms, including bacteria, viruses, fungi and parasites. The study of microorganisms has allowed scientists to discover the pharmaceutical drugs and treatments; such as vaccines and antibiotics, which can be used to treat against the harmful species of microorganisms. The clinical use of these treatments have greatly reduced the mortality due to infectious disease, and have also contributed to the eradication or significant reduction and control of formerly devastating infections such as smallpox, polio and hepatitis, now rare in developed countries.
An infection is the invasion and proliferation of a microorganism, such as bacteria, virus, fungi or parasite, within the body at a site where it is not normally present (MedicineNet, 2017). This concept is important because some microorganisms are present in the body as normal flora, in anatomical sites where they contribute to normal body functioning. For example, bacteria in the gastrointestinal tract contributes to digestion and maintains healthy gut function. When organisms are …show more content…

Public Health’s article on Understanding Vaccines stated that “thanks to increased access to the measles vaccine internationally, the annual death toll from the infection has fallen from almost 600,000 in 2000 to just 122,000 in 2012, a reduction of 79%” (Vaccines, 2017). This statistic demonstrates how crucial research in the field of microbiology is, given its contributed to improving the quality of life worldwide. The discovery of antiseptics and antibiotics were one example of a major advancement in field of medical microbiological research. But the clinical and everyday use of these chemicals have not eliminated the risk bacterial

    The job of the immune system is to keep “foreign” invaders out of the body, or if one gets in, to seek it out and kill it. These foreign invaders are called pathogens, which are tiny organisms that can cause an infection in the body. Pathogens can be bacteria, parasites, and fungi (http://www.niaid.nih.gov/topics/immuneSystem/pages/whatisimmunesystem.aspx).

    Infectious diseases are the disorders caused by organisms such as bacteria, viruses, fungi or parasite who live both inside and outside our bodies and are normally helpful but can cause infectious diseases to the human (body) system under certain conditions. And for a disease to be infectious, there is what is called ‘’chain of infection’’ that takes place before. And this can be seen in the below diagram:

    . Many doctors and patients are unaware that antibiotics are designed to treat bacterial infections, not viral infections (Antibiotic resistance, N.D.). Many bacteria within our bodies are not harmful at all, and some of them actually provide health benefits. The bacteria that are harmful are disease-causing bacteria, which generate sicknesses such as strep throat, the common cold, and ear infections (Get, 2013). Viruses are smaller than bacteria and require hosts, such as plants or animals, in order to proliferate (What, N.D.). Doctors play a vital role in administering antibiotics, for patients rely on their knowledge and expertise in order to receive proper medication for ailments throughout their lives. According to www.acponline.org, 190 million doses of antibiotics are administered every day. Among patients that do not reside in hospitals, doctors prescribe more than 133 million antibiotic programs every year. Of those 133 million programs, it is estimated that over 50 percent of them are unnecessarily prescribed because the doctor is prescribing them for viral infections such as common colds or simple coughs (Antibiotic resistance, N.D.). However, doctors are not the only ones to blame in regard to misuse of antibiotics because their patients are just as guilty when it comes to ignorance in respect to antibiotic usage. Many preventable factors have emerged because of irresponsibility of patients, including self-medication practices and the temptations of cheap, counterfeit drugs, all of which have aggravated drug resistance in the last 20 years (What, N.D.). Also, many patients are unaware of the dangers that can result from leaving medication behind because they don’t use it. It is extremely ill-advised to leave behind eve...

  • Antibiotics Essay

    1033 Words  | 3 Pages

    For many years we have become increasingly dependant on antibiotics to fight off the bacteria that cause diseases in our bodies. Many of the diseases these bacteria and microbes cause are infectious. For these reasons, it has been noticed that bacteria and other microbes are becoming increasingly resistant to the antibiotics prescribed to sick people. Many doctors prescribe antibiotics for common illnesses, yet other medicines such as home remedies and homeopathy could be used instead. As a result, we are using antibiotics too often, as many sources claim we should only be using them once every three years.”Bacteria have shown a remarkable ability to endure and adapt to their environment including the development of different mechanisms of resistance to most old and new antimicrobial agents”. Because of the frequent prescription, the bacteria and microbes that cause these illnesses are exposed to the same type of antibiotics frequently, thus they are able to adapt and build up resilience against these antibiotics. “Bacteria have developed resistance to all different classes of antibiotics discovered to date” . This is a major problem as we rely so heavily on antibiotics to treat serious illnesses that we are running out of options to treat them with. The prescribing of antibiotics for illnesses that are not life-threatening are now resulting in fewer solutions to cure people affected by diseases that can be fatal.

  • The Effect of Interferon on Infection and Disease

    515 Words  | 2 Pages

    When a cell in our body has become infected or has become cancerous it’s surface changes. This is how the immune system can tell good cells from bad ones (the markings on the surface.) Once a bad cell has been recognized our bodies sends cells to destroy the damaged cell and prevent the spread of whatever caused the damage in the first place. The next step our body takes is to have the affected cells start to produce interferons and other helpful substances. These help to fight off unwanted organisms, and also to warn other cells of the invaders and prepare them to resist them therefore preventing the spread of disease.

  • Bacteria

    Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule. The capsule prevents the white blood cells and antibodies from destroying the invading bacterium. Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not cause disease. They release digestive enzymes onto the organic matter. The enzymes breakdown the large food molecules into smaller molecules, which are absorbed by the bacterial cells. Parasites live on or in living organisms, and may cause disease. A few types of bacteria are Autotrophic, they can synthesize the organic nutrients they require from inorganic substances. Autotrophic bacteria are either photosynthetic or Chemosynthetic. The photosynthetic bacteria contain chlorophyll that are different from the plant chlorophyll. In bacterial photosynthesis, hydrogen is obtained by the splitting of compounds other than water.

    Microbes are microscopic life forms, usually too small to be seen by the naked eye. Although many microbes are single-celled, there are also numerous multi-cellular organisms. The human body has 10-100 trillion microbes living on it, making it one giant super-organism. Since the first link between microbes and diseases was made, people have been advised to wash their hands. Scientists, however, have recently started to investigate more closely how the microbes that call the human body home affect our health. While some microbes cause disease, others are more beneficial, working with our bodies in many subtle ways.

  • Essay On Microbiology

    1989 Words  | 4 Pages

    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

  • Five Benefits of Microbes (Microorganisms)

    696 Words  | 2 Pages

    Microbes are major key components in both are homes and industrial food preparation. There are number of lactic acid which is a form of bacteria which is a large group of beneficial bacteria used in certain foods while they are getting prepared such as yogurt, cheese, sour cream, butter milk and other type of fermented milk products. Things such as vinegars are produced by bacterial acetic acid fermentation. Yeast is also major use in the making of beer and wine and also for the leaving of breads. This also involves fermentations to convert corn and other vegetable carbohydrates to also make beer, wine or gasohol but also bacteria is the agents of are other foods. Other fermented foods will include things such as soy sauce, olives and cocoa. (Microbes and human life, 2013) Single cell proteins are known as dried cells of microbes which are used in protein supplement shacks. They are also called “novel food” and “minifood”. The production of this requires micro-organisms which then serve as the protein source and then the substrate which is biomass which they grow on them. There are a number of both these sources that we are able to use for the production of single cell protein (SCP). The micro-organisms used belong to the following groups of Algae, Fungi and bacteria.

  • Reflection On Microbiology

    877 Words  | 2 Pages

    Knowledge is power when discussing the classes you have taken in college and how it affects your everyday life. Microbiology is one of those important classes where although for a majority of majors you do not have to take it and therefore will not learn the information discussed in it, other majors such as biology and nursing require you to take it. They will require you to take it because you will encounter some of the information being taught in it in the work field. As a nurse practitioner I have worked in the field with many patients who were diagnosed with Leprosy, Escherichia coli, Salmonella and other bacterial diseases. All of these diseases that I have encountered in patients were ones I was familiar with due to learning about them as a student in microbiology at CSUB. My children plan on
