Pathogenicity and Immunology; Host resistance and the immune response 2
For this module you are to do the following: Discuss the role of the immune system in protecting the body from the pathogenic and non-pathogenic microbes selected in Module 1 and 2. How would the body's immune response differ if it was previously exposed to the same pathogen 2 years ago as compared to an initial exposure? Please upload your M4 SLP when it is completed. Your assignment is due by the Monday following the end of this Module. Please upload your case assignment. Session Long Project Assignment Expectations Length: Each module SLP should be approximately a minimum of 2-4 pages or approximately 500 to 650 words. References: At least two references should be included from academic sources (e.g. peer-reviewed journal articles). Required readings are included. Quoted material should not exceed 10% of the total paper (since the focus of these assignments is critical thinking). Use your own words and build on the ideas of others. When material is copied verbatim from external sources, it MUST be enclosed in quotes. The references should be cited within the text and also listed at the end of the assignment in the References section (preferably in APA format). Organization: Subheadings should be used to organize your paper according to question Format: APA format is recommended (but not required) for this assignment. See Syllabus page for more information on APA format. Grammar and Spelling: While no points are deducted, assignments are expected to adhere to standards guidelines of grammar, spelling, punctuation, and sentence syntax. Points may be deducted if grammar and spelling impact clarity. The following items will be assessed in particular: Relevance (e.g. all content is connected to the question) Precision (e.g. specific question is addressed. Statements, facts, and statistics are specific and accurate). Depth of discussion (e.g. present and integrate points that lead to deeper issues) Breadth (e.g. multiple perspectives and references, multiple issues/factors considered) Evidence (e.g. points are well-supported with facts, statistics and references) Logic (e.g. presented discussion makes sense, conclusions are logically supported by premises, statements, or factual information) Clarity (e.g. writing is concise, understandable, and contains sufficient detail or examples) Objectivity (e.g. avoid use of first person and subjective bias)

Module 2 SLP
B MIC100 - Microbiology
9 Dec 13
In Module 1 you selected an example of resident microbiota.
In this Module, selected another resident microbe from "Chapter 2: Host-Microbe Interactions" in A Concise Manual of Pathogenic Microbiology, that can cause disease in humans.
1. Discuss the germ theory of disease.
2. Describe the human diseases which are produced by the pathogenic microorganism selected. Does it exist in a non-pathogenic state as well? Under what health condition can the disease be produced?
Include in your discussion:
- The differences between eukaryotic and prokaroytic cells.
- Three phenotypic systems used to classify microbes.
- Use the classification system discussed to classify each microbe selected in Modules 1 and 2.
Please upload your M2 SLP when it is completed.
The Immune System
Name:
Institution:
The sole function of the immune system in the human body is to protect the body from the myriad of potentially damaging foreign bodies and diseases.When the system is functioning properly, it attacks all the potential threats while still being in a position to identify the pathogens from the body cells (Ayuk&Abrahamse, 2012).
The system is composed of the spleen, bone marrow, lymph nodes and the thymus. The white blood cells are produced in the bone marrow, while the lymph nodes produce the lymphocytes that include the B-cells and the T-cells.The average human has approximately 600 lymph nodes and they help trap the pathogens and activating the white blood cells. The thymus organs located in front of the trachea helps the white blood cells to differentiate the foreign bodies from the body cells. The spleen on the other hand helps in filtering the blood while at the same time responding in kind to the pathogens with the help of the white pulp. The red pulp in the spleen helps with the removal of the damaged red blood cells and storage of the platelets.The T-cells mature in the thymus are responsible for attacking the cancerous and infected cells in the body. The B-cells on the other hand are responsible for the protection of the body cells from the toxins and the bacterial cells that enter the body system (Shomon, 2013).
The human body is highly complex much likes most of the vertebrates as they have two levels of immunity protection. There is the specific and the non-specific immune system. The latter, as the name suggests is more general and include lines of defence such as the mucous membranes and the skin. The specific immunity involves the lymphocytes which are produced in response to specific pathogens. There are two types of the lymphocytes namely the T-cells and the B-cells, all of which are specific to millions of the different pathogens and antigens. The b-cells have the ability to mature and differentiate into the plasma cells which then produce the antibodies called the antibodies. It is the T-cells that assist the B-cells into initiating the process, where the former respond to the antigens that they are coded for, resulting in the proteins and eventually the antibodies (Patient, 2013). The Antigen Presenting Cel...
