Pathogen Analysis

The immune system depends on the body’s structures to help it function. For instance, the skin acts as the “body’s first line of defense.” If a pathogen finds a breach in the skin barrier, it is the circulatory system that must now signal the immune system of the invader. Shortly after, white blood cells will be notified of the infection and will target and destroy the pathogen.

Isolating and characterize a novel phage from the environment requires several steps and several frustrations. By isolating and investigating a phage found in the Pullman region can hopefully lead to a newly discovered phage that can help researchers discover more about the life cycle and process of phage infection. Some phage infection can be good due to infecting the bacteria that is not wanted or is harmful to the environment or humans. Within this lab, there were steps taken necessary to isolate a novel phage that was obtained from the surrounding Pullman area. This report reflects plaques being isolated but then stopped due to errors and loss of plates. The final touches and procedures were accomplished with a given DNA ladder that was

The body’s protection against viruses, bacteria and other types of invasions is our immune system (Tortora, 2014).

There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient, so as to know how it can be treated, to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of unknown bacteria. The identification process can be completed with a series of deferential stains and biochemical tests. Creating a dichotomous key helps to limit the amount of biochemical tests done on an unknown organism and by observation

Almost instantly I came upon the immune system. A flock of geese was huddled together above an evergreen grass at Lighthouse Park. “The Lighthouse Park offers an excellent spot for spreading out a blanket on the grass and taking in views of both Manhattan and Queens before heading back down the island.” Also, “an assortment of barbeques and benches, indicated that the area is a popular spot for hot summer evenings with friends and family.” Anyhow, there was a strange vibe that provoked me as I watched the geese. They seemed clotted up as if they were defending the island against infectious organisms and other invaders. They seemed weak–unable to follow the series of steps called the immune response. They seemed lost–unable to detect pathogens. They seemed malnourished – unable to protect the body by working in unison with cells, tissues, and other organs. However, each goose seemed hopeful and kept fighting. By plodding past the innocuous wind, my friends and I became the island’s diet. I reached in my medical bag and pulled out a loaf of bread. We called out and like a current, we, electrified and inspired the crowd. Then we encrypted the gaggle with Vitamin A, Vitamin B2, Vitamin B6, Vitamin C, Vitamin D, Vitamin E, and Zinc. Soon enough, the geese were in action and were ready to take flight. Sadly, the omnipotent

Our bodies were specifically designed to fight off diseases organically through the use of our immune system. When an antigen enters our bodies, our immune system immediately acknowledges its presence and produces antibodies to fight off the foreign organism. The antibodies will search for the disease organism and will dismantle it when found. The next time the body comes in contact with

Based on research and observation, we now know that infectious diseases are caused by microorganisms (pathogens) and that the immune system provides defense against infectious diseases.

macroparasites. These also vary in size and shape, and also in the type of diseases they cause in

The body responds differently to an infection, depending on whether it is a virus or a bacterial infection. Generally, viruses are considered to be more dangerous, but aside from generalities, there are also pathophysiological differences in the ways in which both viruses and bacteria (invasive organisms) infect human beings (hosts). When a virus is the agent that is infecting the host, the goal of the virus is to invade on a cellular level and replicate itself. “Once inside, the cells of the immune system cannot ‘see’ the virus and therefore do not know that the host cell is infected. To overcome this, cells employ a system that allows them to show other cells what is inside them” (Immune, 2015). The virus then uses the cell in order to make proteins and replicate itself, further compromising the immune system. The immune

Three of the body’s physical and chemical barriers against infection are the skin, the respiratory tract and the immune system. The skin prevents microorganisms from entering the body. The respiratory tract is lined with mucous membranes and cells that sweep out foreign matter, while other particles may be eliminated through a cough. The immune system defends against infection through cells that distinguish foreign cells from the bodies own cells. The immune system is able to eliminate microorganisms from the body.

This lab and its procedures are all about finding out the unknown identification of a given bacteria. The lab consists of specific techniques, tests, chemicals, and vocabulary that are necessary for the finding of the bacterial identity. A bacterium is randomly assigned and it is a group effort to find the bacteria name through many of its specialties and characteristics. An example of classifying it would be to determine whether the bacteria is catalase negative or positive, or if the species is gram negative or positive. This lab is of huge significance because of its medical microbiology connections. Scientists Gurtler and Stanisich explained the connections more eloquently. They stated, in their medical article, that, “Medical microbiology

Immunotherapy is a form of medical treatment intended to stimulate or restore the ability of the immune system to fight infection and disease. This can be by inducing, enhancing, or suppressing an immune response. Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while those that reduce or suppress immune response are suppression immunotherapies. Active immunotherapy has been effective against agents that normally cause acute self-limiting infectious disease. However, a more effective immunotherapy for chronic infectious diseases or cancer requires the use of appropriate target antigens; the

Have you ever wondered how your body works? Did you ever think about how your body defends itself from outside invaders? Remember the last time you were sick. Did you know how your body fought and killed the sickness? All these questions can be answered by learning about one of the most important systems in your body, the immune system.

Our immune system is the second most complex system in our body. It is made up of organs, cells and proteins that work together to protect our bodies from harmful bacteria, viruses or other microorganisms that can cause diseases. Usually we don’t notice our immune system defending us against pathogens, but if the pathogen (harmful microorganism) is aggressive or if our body hasn’t ever come into contact with it, we can get sick. The jobs of our immune system are to recognise pathogens, as well as neutralise and remove them from our body. Our immune system also has to fight our own cells if they have changed due to an illness, for example, cancer. (1)
