Essay Instructions:

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. Recommended format: Module 2 - Structure and Evolution of Microbes Introduction: Prokaryotes, Eukaryotes and the three pheontypic systems used to classify microbes Organism 1, classification Organism 2, classification Comparisons and contrasts, pathogenic vs non-pathogenic states, opportunistic or symbiotic? Note: A "PR" grade will be assigned to SLP Module assignments where critical thinking is not an important factor. The "PR" grade means "Progress"; however, in practical terms it means that the student's work is satisfactory. 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)

Pathogens

Institution:
The germ theory
Germ theory states that diseases are caused by the presence and actions of specific microorganisms within the body. This theory was developed and popularized from the mid 1800s in Europe and the United States superseding the then used theories of diseases miasma and contagion. It fundamentally changed the practice of medicine from then onwards. It is still the underlying theory that guides contemporary biomedicine (Campbell & Farrell, 2012).
Human diseases produced by pathogenic microorganism
Pathogens have different ways of attacking and similarly one has various ways of defending themselves. There are different types of pathogens: bacteria, viruses, fungi, protozoa, and helminthes. Diseases that are caused by the bacteria as a pathogen are largely described in this paper.
Bacteria are unicellular and have no definite structure. Their genomes are usually circular and double stranded. Most of the bacteria reproduce through binary fusion though they are still grouped in the Kingdom Monera group. These bacteria are usually divided into two groups: Gram-negative which appear pink after staining and the Salmonella typhi, which are the cause of typhoid fever. Bacteria are prokaryotic in nature, as a result, associated with less protein than the eukaryotic genomes (Iacobellis, 2003).
Eukaryotic and prokaryotic cells have a number of differences in their structure, which is highly depended on in their distinction. The most basic differentiation is that eukaryotes have nuclei, which contains their DNA, whereas in prokaryotes the membrane does not bind the genetic material. In eukaryotes, most metabolic processes are performed by the mitochondria and the chloroplasts. The process is similar in the prokaryotes but it occurs across the cell membrane. Genetic makeup of the two also varies in that prokaryotes have very compact genes on their chromosomes especially because they do not have large encoding regions between their genes and lack introns. The last but not very significant difference is that prokaryotes are muc...
