Essay On Advantages And Disadvantages Of Antibiotics

Vaccines operate by introducing a weakened version of the virus, or a strand of a protein from the bacteria into the immune system. In turn, this insertion causes the production of antibodies which help to fight the actual infection, by attacking the virus upon its entry into the body (“Vaccine” 1-2). Previously, vaccines revolved around observations that humans will develop an immunity to a disease they are exposed to, given they survive (“Vaccine 1). However, vaccinations are far

Many infectious diseases such as measles and chickenpox can be prevented by vaccines (Nordqvist. C, 2017). Taking a good care on the basic hygiene such as frequent and thorough hand-washing also helps protect from most infectious diseases. There are two levels of immunity in the human immune system which is the specific and nonspecific immunity. To defend the foreign materials that perceived to be harmful, the human body protects itself though the

For example, polio vaccine contains poliovirus. But the antigens in vaccines are weakened to the point that they don’t cause disease. However, they are potent enough to make the immune system produce antibodies that lead to immunity. The person gets protection without having to get sick. Through vaccination, people can develop immunity without suffering from the actual diseases that vaccines prevent.

This is how the body floods the area with oxygen, nutrients, antibodies to fight off invading organisms, and fibroblasts to carry on the wound-healing processes to the injured area. You may, however, see how sustained levels of cortisol in the bloodstream may actually interfere with the natural healing process and progressively decrease the body’s resistance to infections, swelling, and tumors of all

In addition, phages can also overcome host resistance mutations. However, they can be eliminated by the body's defense mechanisms. Phage therapy has been used as an alternative to antibiotics. The use of natural phages to treat bacterial infection has very known history in the western medicine. Antibiotics are one of the most successful forms of chemotherapy in the history of medicine.

The theory of evolution by natural selection and the evidence presented by Darwin. The evolution of biological organisms describes the changes within different populations which creates variability in their phenotypes and genotypes. The fundamental basis of evolution, is that every living individual is related by a common ancestor (Strickberger,2000.). Charles Darwin, in 1859, published one of the most credible and compelling theories of evolution, in his book ‘the origin of species’ (Darwin and Beer, 2008), which best explains the theory of natural selection.

In order for vaccines to work appropriately, they have to operate in a very convoluted way to make sure they live up to their standards. 1. Vaccines are developed by using the bacteria’s specimen that has been either killed or damaged which are dissolved in a solution. When the vaccine is injected into the body, the specimen revives that person’s immune system. After being injected, the immune system will now fight against the microbe by forming antibodies.

Antibiotic, a chemical substance produced by micro-organisms which has the capacity, in dilute solution, to inhibit the growth of or destroy other micro-organisms (A. Porteous, 2008). Antibiotics are used to treat and control infectious diseases in the human body, animals, and even

After treatment, addition, new blood vessels may develop. The photodynamic therapy also aims to destroy the fragile blood vessels, but this is achieved by injecting a drug that adheres to the surface of said vessel, and subsequently illuminating the eye with a light that activates the drug. The activated drug destroys blood vessels only, without affecting healthy tissues. This treatment does not restore lost vision, but retards the progress of the disease.

Do you think vaccination is important? Vaccination is very important because it is the most effective way to prevent an outbreak of infectious disease. Vaccination is the introduction of vaccine or antigenic material into our body to incite our immune system to fight with the pathogen and acquire immunity towards the disease that is caused by the pathogen. After the vaccine is successfully introduced into our body, it can protect us from infectious diseases.

Due to the smallpox epidemic threat, the inoculation procedure got popular in other places and for other similar diseases. The benefits of inoculation outweighed the risks for children. Boylston figured out inoculation could produce certain type of immunity for the virus which can terminate the infection and save lives. Also, he ensured from his experiments that the inoculation process had less fatal structure of the disease in the human body. The author illustrated that several obstacles were overtaken to prevent the outbreak from spreading, a contamination which infected numerous people in 1721, and there were many controversies about the inoculation process and experimentation to inoculate the disease into a healthy person.

If you can get the vaccination, you hands down should have to. You are not only protecting yourself, but those around you. The vaccine video speaks well in that when given a vaccination, you rarely get infected twice. Taking the vaccination reduces disease and spread by a stronghold. You are helping those sick, and those who cannot receive vaccination.

It allows people with possible allergies to certain vaccines become aware of that, and not be put at risk. One of the reasons the government should make it mandatory to get vaccinated, is mainly because it helps to prevent you from getting sick. This is especially important for people with weak immune systems, because they would get sicker than a normal person. Also, vaccines are important because, “the viruses and bacteria that cause illness and death still exist and can be passed on to those who are not protected by vaccines” ("Top Reasons to Get Vaccinated." 1).

The triclosan antiseptic is the most effective killer of E. Coli bacteria; however, recent studies have shown it could be harmful to human health. We recommend to doctors, hospitals, schools and families to use non- triclosan based products to help kill bacteria. Although the most effective killer, triclosan could potentially contribute to the development of antibiotic-resistant germs and be harmful to the immune system. Scientists must find the balance between effectively killing bacteria and the safety of human

However, when our bodies encounter unfamiliar antigens our immune system may not be able to fight off the antigen before infection occurs resulting in us becoming sick. This is where vaccines can be beneficial. They work by preparing the immune system for possible exposure to a virus by injecting a weakened or dead form of the virus into the bloodstream. Hence, infection does not occur as immunity is achieved and the immune system knows how to combat the foreign invader when exposed to a stronger form of the virus. As a result of vaccination, antibodies will be produced that attack the weakened virus without infection occurring as it would with natural infection.
