The value and ethics of vaccinations is hotly debated‚ and many parents choose not to vaccinate their children. Older people are at greater risk of contracting diseases. There are many valid reasons to vaccinate. Vaccines aid in preventing disease‚ saving lives‚ and keeping the spread of disease at bay. As there are many instances of plagues throughout history‚ vaccinations have been a key component in the prevention of great illnesses in the last hundred years or more. Polio was a death sentence

Colonisation is when microorganisms become a part of the normal internal flora. These mircoorganisms are not harmful to the human‚ but when they reproduce and multiply they join the natural flora of the body and they all live together. Infection is when a pathogen (infection causing microorganism) invades the body and start to reproduce in any tissue of the human. Examples of infection include the common cold‚ skin infections (warts) and gastroenteritis. Disease refers to a disruption in the sturture or funtions

the result of a patient’s immune system being exposed directly to a weakened or dead form of the pathogen and reacting by developing immunity to the agent. This active immunity‚ whether natural or artificial‚ is long-lasting and often life-long. Specific immunity is a small part (subsystem) of the overall immune system that is made up of highly specialized‚ cells and processes that remove pathogens or prevent their growth. The specific immune system is one of the two main immunity strategies found

TOXOPLASMOSIS – HOST/PATHOGEN RELATIONSHIP Toxoplasmosis is a parasitic disease caused by the coccidial protozoan Toxoplasma gondii (see table for full scientific classification) (Table courtesy of Toxoplasmosis. 2013). Toxoplasma gondii are obligate intracellular protozoan parasites normally found in the intestinal tract. Toxoplasma is an especially promiscuous parasite‚ it infects nearly all mammalian species‚ most nucleated cell types‚ and much of the human population. Although it lives in

The main blood vessels are the following: Aorta. The aorta is the largest and principal artery in the body. From the aorta branches lead to all the organs of the body‚ supplying them with oxygen and nutrients. Coronary Artery. The coronary artery is also a branch of the aorta. It supplies the heart tissue with oxygen and nutrients. Pulmonary Artery. The pulmonary artery arises from the right-hand upper corner of the roght ventricle. It branches into the left and right pulmonary arteries which lead

result of physical injury. In this essay I will explore the causes of disease in humans‚ in terms of pathogen infection‚ viruses‚ lifestyle factors and genetics. Infectious diseases are caused by pathogens; any organism that causes disease. Pathogenic microorganisms include bacteria‚ fungi and viruses. Pathogens cause disease by producing toxins and damaging cells. An example of a disease causing pathogen is the cholera bacteria‚ Vibrio Cholerae. Cholera is a bacterial infection caused by drinking contaminated

are caused by pathogens and transmitted through the air. These viruses and bacteria can be spread through coughing‚ sneezing‚ laughing or through close personal contact. These pathogens ride on either dust particles or small respiratory droplets and can stay suspended in air and or are capable of traveling distances on air currents.[1] Often‚ airborne pathogens or allergens cause inflammation in the nose‚ throat‚ sinuses and the lungs. This is caused by the inhalation of these pathogens that affect

then been able to be replicated and inserted into genetically modified plants in order to produce a plant with the capability of producing higher levels of the antigen for harvest. Traditionally‚ vaccines are prepared using a version of a disease or pathogen which has been modified by inactivating the disease-causing part of the gene and administering it to organisms in sufficient quantity to induce an immune response. With this new technology‚ the antigen which induces the immune response has already
