Post by Nigela Couch3 days agoRe: MRSA Discussion ForumMRSA, also known as methicillin-resistant staphylococcus aureus, is an infection caused by a bacteria that is resistant to a wide variety of medications. As a result, the infection is difficult to eradicate from the body. Similar to the situation with multi-drug resistance Mycobacterium TB, this staphylococcus is emerging as a new anti-biotic resistant bacteria strain. Because humans are prone to bacterial infections, an illness as severe as MRSA can be clinically hazardous if it is not treated in the appropriate manner. Recent discussions about the diagnosis and management of MRSA include both traditional approaches that rely on taking samples (body fluids) from the patient and performing lab cultures, as well as more sophisticated approaches like PCR detection of the pathogen, which provides results in a short period of time. These cutting-edge diagnostic techniques are incredibly quick and precise, and they contribute to a more accurate diagnosis of the illness.

Innate Immunity.

For this assignment we are back to the Concept maps.
For thist Map your topic is Innate Immunity. After reviewing the Video and powerpoints describing innate immunity, please build a map or web showing the connection of the different parts and molecules of innate immunity in the defense and resolution of a microbial infection. Please make sure to include and expand on the following:
physical structures
cells
molecules
substances
pathways
organs
activities
Make sure you limit yourself only to addressing Innate Immunity and not Specific/Adaptive immune cells.
I will be looking for the how you interconnect all of the different components you mention.
Just as a reminder, I have included our concept map figure from the first module.

Post by Niasia Turman4 days agoMRSA Discussion ForumMethicillin-resistant Staphylococcus aureus, or MRSA, is an antibiotic-resistant kind of bacteria. Most frequently, MRSA causes skin infections. It can sometimes result in diseases such as pneumonia (lung infection). Sepsis, the body’s violent reaction to an infection, can develop from untreated MRSA infections if they grow severe. MRSA may infect anyone.

Post by Niasia Turman4 days agoMRSA Discussion ForumMethicillin-resistant Staphylococcus aureus, or MRSA, is an antibiotic-resistant kind of bacteria. Most frequently, MRSA causes skin infections. It can sometimes result in diseases such as pneumonia (lung infection). Sepsis, the body’s violent reaction to an infection, can develop from untreated MRSA infections if they grow severe. MRSA may infect anyone. Crowded situations, skin-to-skin contact, and the use of shared tools or supplies all raise the risk. Some MRSA carriers may later get an infection with MRSA. MRSA infections frequently start in areas of non-intact skin, such as abrasions or wounds. Athletes, children in daycare and schools, military personnel residing in barracks, and patients undergoing inpatient care, surgery, or medical are at a higher risk of this infection. Until they have healed, bind your wounds with clean, dry bandages. Observe the wound-care guidelines provided by your healthcare practitioner. MRSA may be present in the pus from infected wounds. Avoid popping or picking at the sore. Bandages and tape should be disposed of in the ordinary trash. Frequently wash your hands. You should frequently wash your hands with soap and water or with an alcohol-based hand rub for yourself, your family, and anybody else in close contact, especially after changing a bandage, handling an infected wound, or touching soiled clothing. Personal things like towels, washcloths, razors, and clothing, even uniforms, should never be shared. Clean your hands after handling soiled clothing and wash the laundry before letting others use it. Using these precautions can simply lower the risk of yourself and others from being infected.

What is the test, what is the purpose of the test, any special requirements for collection, any regulations for the collector.

You will choose a laboratory test and follow it from the patient to the returned result, describing each step as learned in the four weeks of class.
Title Page
Introduction- What is the test, what is the purpose of the test, any special requirements for collection, any regulations for the collector.
Pre-analytic: What happens when the test gets to the lab. How is it processed?
Analytic: How is the test performed? Test methodology, equipment used, operator requirements, lab operations requirements.
Post analytic: What happens after the test is run? How is it validated, how is it released to the ordering physician.
Describe current applicable legislation.
Define a lab budget for your test.
Discuss, marketing, communication and pricing strategies for the test and your lab
Discuss personnel considerations including communication, conflict resolution.
References (minimum of 4 total)
Total length should be approximately 7-10 pages, Times New Roman 12 pt. typeface. Use APA format conventions, double spaced with one-inch margins on each side.

You will pick a microorganism for your paper on pathology or microbe-environment interactions. The organism cannot be one of the ones listed in the syllabus. Select a pathogen/microbe from current events that is an emerging or reemerging concern to you or people in your area. Provide local epidemiological data/statistics for the organism. Your topic DOES NOT need to be approved by the instructor.

Select a pathogen/microbe from current events that is an emerging or reemerging concern to you or people in your area. Provide local epidemiological data/statistics for the organism. Your topic DOES NOT need to be approved by the instructor.
Your paper must include:
Introduction to the organism (structure, cell type, morphology, metabolic requirements, natural reservoir, history, etc.)
Introduction to the disease(s) caused by the organism (epidemiology, signs, symptoms, etc.) OR introduction to the environmental impact of the organism
List and describe factors employed by the organism to assist in its growth, reproduction, culture conditions, host/pathogen interactions and/or virulence. (e.g. nitrogen fixation, symbiotic interactions etc.) Categorize virulence factors by mechanisms of action (Immunity Avoidance, Tissue/Cell Lysis, Colonization/Spread)
Discussion of treatment/prevention options for the disease(s) caused by the organism (Antibiotics or other chemotherapeutics given as part of treatment and their mechanisms of action, Vaccines available and type)

Microbiology: The word micro is called small and biology is called thought about life. Microbiology is the study of a variety of living organisms which are invisible to naked eye like bacteria and fungi and many other microscopic organisms.
