Immunology is the study of diseases associated with excesses and deficiencies of the immune system.
<h3>What is immune system?</h3>
A network of biological processes called the immune system guards an organism against disease. It recognizes and reacts to a wide range of pathogens, separating them from the organism's own healthy tissue, including viruses, parasitic worms, cancer cells, and things like wood splinters. There are two main immune system subsystems seen in many species. The innate immune system responds to a variety of events and stimuli in a predetermined way. The adaptive immune system learns to recognize chemicals it has previously met and responds to each stimulus in a way that is specific to that stimulus. Both rely on molecules and cells to carry out their respective tasks.

Answer: The technician would expect to see "purple, spherical-shaped organisms arranged in chainlike formations." This will give the gram stain confirmation of having streptococcus pyogenes. With the confirmation, the patient can receive antibiotics to kill off the bacterial organisms. Usually, penicillin is given in these cases unless the patient is allergic.
The technician is taught in school how to look for each strain since it is important to diagnosis this correctly. If the gram stain had of been pink or purple with grapelike clusters, it would have not of been Strep and there would have been a different diagnosis.
Bacteria strains are different shapes, various sizes, and can be found in multiple arrangements. Since the wall of the cell is rigid, the bacteria will not lose the shape. The bacteria have to separate parts, the shape and how they are arranged. When there are grape-like structures it indicates staphylo. The chains will indicate the presence of strepto. The shapes that are rods will be bacilli, the spiral ones will be spirillum, and the sphere shapes are cocci.
