The Human Immune System

Great Essays
Links between the human immune system, pathogens, antibiotic resistance and mutations are discussed in this report. It is stated that the antibiotic resistance and overuse of vaccine has contributed to the increased incidence of emerging diseases and resistance to their controls and treatments. The human immune system is the protection of the body against potentially damaging foreign bodies and other disease. Pathogens are organisms, including a bacterium, a virus or a fungus and these causes diseases in other organisms. Functions of the immune system and the use of vaccines, antibiotics and the effects of resistance to antibiotics in medicine and agriculture are also discussed. Preliminary research will determine whether the statement is factually …show more content…
Bacteria grows and reproduces inside cells of the human body. Growing and dividing, bacteria make toxins or poisons and toxins damage the cells. Symptoms include headaches, high temperature and rashes that is caused by the way the human body responds to toxins and damage create from bacteria. Once the body is infected by a virus, the genetic material of the cells are overtaken. These viruses, direct cells to produce copies of itself until it results in an increase of infection to other cells. The way the human immune system responds to these cells bursting, disease symptoms develop. Pathogens are produced and can be spread in various ways to other individuals. The immune system has a part called non-specific immunity as it assists the body to prevent pathogens entering the body and this area of the system is always present but is not activated in its response to particular pathogens. Altering the micro-biome and weight gain, are contributing factors to the possible dangers regarding the overuse of antibiotics. Despite these many concerns, antibiotic vaccines and prescriptions are continually used and in some cases, are used …show more content…
A vaccinations’ purpose is to introduce a pathogen such as bacteria or viruses to the immune system, which the person can develop immunity to the pathogen while not experiencing disease. A portion of the pathogen is injected into the body so the immune system can easily recognise it as an invader and since the pathogen is inactivated, there should be no cause of disease. Vaccinations produce an incorrect immune response and the vaccines used today were developed through poor understanding of the function of the immune system itself. The paper titled, “Vaccine Strategies: Targeting Helper T Cell Responses”, addressed in 1995 considers the need to elicit the T cell response through the vaccination. “Although vaccination has been used for centuries, the technologies are largely empirical with little understanding of the underlying immunological principles and physiological mechanisms.” ("How Vaccines Affect The Immune System | Vaccine Decision” 2011-2016). This means, that although vaccinations have been continuously used throughout the past, present, and soon the future, the understanding of how vaccines positively help the body without any side effects is slim. Antibiotics affect the human immune system by permanently changing the system and killing bacteria. Good bacteria are eliminated with the bad bacteria, so therefore the ability for the body to produce the appropriate immune cells is altered.

    The system produces a number of substances include cationic antimicrobial peptides (CAMPs) such as defensins, bacteriolytic enzymes such as lysozyme etc. The production of these substances ensures that the microorganisms are destroyed before they get an opportunity to cause infections [4]. However, S. aureus has developed mechanisms, which enhance the evasion of the host immune system. The host’s body produces effector proteins after microbial invasion; nevertheless, S. aureus produces molecules that inhibit these proteins. Another mechanism used by the microbe involves binding of immune regulators produced by the host through the production of surface-bound molecules [5, 6]. Host cells produce Antimicrobial Peptides (AMPs) that help in exert cytotoxic activity on microorganisms. The capacity of S. aureus to counteract the activity of the AMPs is another mechanism that enables it to evade the immune system. The microbe has the ability to inhibit the cytotoxic effect through the alteration of the AMP by production of staphylokinase [4]. Neutrophil-mediated processes and phagocytosis are crucial in the host innate immune system. S. aureus has the ability to evade these systems and cause infections in the host and the processes involve many secreted and cell-surface-associated proteins [7]. The ability of the organism to resist antibiotics is another mechanism…

    When invasive cells such as viruses or bacteria enter the body, then lymphocytes produce antibodies to neutralize these intruders that are called antigens. A healthy individual creates millions of antibodies a day, which help maintain a healthy body without illnesses. Certain malignant antigens however are able to attack the body before the antibodies are able to be generated. Many diseases in the past have decimated large portions of the human race, such as: measles, mumps, rubella, varicella, influenza, polio, and hepatitis. An immeasurable amount of men, women, and children throughout history were defenseless against these diseases and had their lives ruined by arduous illnesses. With the invention of the vaccine, through injecting dead or weakened diseases, a person’s body is able to defend itself against otherwise vigorous diseases.…

    Antibiotic resistant bacteria is a big concern now a day due to the use of excessive and improper use of antibiotics. It is very common for people to star taking an antibiotic and stop the regimen as soon as the symptoms are gone. With this practice, bacteria that were not killed by the antibiotic but were exposed, are capable of becoming immune to it. This immunity or resistance can be passed on from bacteria to bacteria through the exchange of their genetic material using some of the methods of horizontal gene transfer. As a result, the resistance acquired by one pathogen can be passed to other pathogens.…

    Vaccine are substances that ugally do not cause illness but even so the immune system responds to them. Traditionally vaccines are pathogens themselves, today it is possible to genetically engineer bacteria to mass-produce a protein from pathogens, and this protein can be used as vaccine. This method has produce a vaccine against hepatitis B, a virus-induced disease, and cine against malaria, a prtozonan induce disease. Vaccinations can be very effective in men women and children, and therefore still been study and tested and is used to save…

    The human body is protected against infections by the immune system. The disease occurs when the normal function of tissue is impaired. Health organizations have for a long time tried to understand all causal agents of diseases as fight strategies against these agents including understanding surviving strategies, their cycle, and multiplicity once they infect a human being. This has facilitated discovery of therapeutic drugs for various diseases (Klepac et al., 2013). Vaccination against different diseases has led to the elimination of historically deadly disease such as smallpox. Treatment is applied equally against bacterial, viral, fungal and protists disease (Field et al., 2004). Generally, vaccination is effective against bacterial…

    The role of vaccinations is to bring in a pathogen example virus, bacteria to the immune system so that it can build up immunity to the pathogen without having to have the disease. This chemical is injected into the body to get the immune system to recognize a portion of pathogen virus. In normal circumstance, most pathogens enter a person through the nose or mouth. In most vaccinations, the pathogen enters through an injection, completely bypassing the normal occupations of the immune system's defence. This would not be a major problem if the injection contained simply a killed or inactivated pathogen, as this would not pose a threat. However, since the pathogens are not a threat to cause an immune system reaction, vaccines contain something…

    The human immune response is a complex, layered system that uses multiple defense mechanisms which function in harmony to protect the body from infection and illness. There are two main types of immune response, the innate and acquired, and while these responses are related and sometimes overlap, they use separate processes to defend against invaders. Working as a whole, innate and acquired immune responses protect the body from infectious organisms. Infectious organisms that can cause disease include “bacteria, viruses, protozoans, fungi, parasites and prions (infectious proteins)” that are known as pathogens (Goodenough 238).…

    The innate immune system utilizes protective barriers which act as the first line of defense against infection. Those protective barriers include the skin, gastrointestinal tract, respiratory airways and lungs, nasopharynx, and the eyes. The skin does not provide a suitable environment for bacterial growth due to the presence of oil glands in the dermis layer, lack of blood vessels, and the inability to retain moisture (Mayer, online). The…

    The purpose of the immune system is to defend the body against any foreign invaders that might do the body harm by using a series of immune responses to prevent the entry or survival of any foreign body. The human immune system uses three types of responses: barriers, nonspecific defenses, and specific defenses. Barriers and nonspecific defenses are innate or rather they are the defenses humans are born with while specific defenses are acquired throughout our lifetime. The immune system is also meant to destroy any hazardous cells like any infected with a virus or any cancerous cells. It is composed of the thymus, the spleen, the lymph nodes along with a variety of cells like leukocytes and antibodies.…

    What is a vaccination? How do they benefit individuals? Is there any harm that can come from receiving a vaccine? A vaccination is defined as the injection of a killed or weakened infectious organism in order to prevent the disease. Scientists make vaccines by first making the pathogen, or disease-causing microbe, in mass amounts in a laboratory. The pathogens must then be altered to ensure that the disease is not actually triggered. Alterations of these pathogens can be done in different ways. Scientists can weaken the pathogen by growing it over and over and selecting a strand that is less dangerous, take out the part of the pathogen that causes the immune response and use it in the vaccine, or use the toxin that the pathogen makes then inactivate it (Tetanus vaccine). Finally, the treated pathogen is combined with things such as stabilizers and preservatives to then produce the actual vaccine dose. Vaccinations are purposely designed to prevent a person from getting sick. Most vaccinations do actually prevent the disease that they inject through the vaccine; however, one still may be diagnosed with the illness if the vaccination is a “live” pathogen. For example, the flu is impossible to obtain once the vaccination is injected. Although one may receive flu-like symptoms, it is impossible to actually be…
