- hello sir Explain in detail about Sequence of host reaction following implantation of medical devices or biomaterial???9. Define adherence of the bacterial disease process. Why is this step so important for bacterial infections? 10. List the four ways that bacteria evade or subvert the immune system during the Establishment and Surviving Host Defenses stage of the bacterial disease process. 11. Define exotoxins. How do exotoxins damage and destroy cells? Can exotoxins affect all cell types in the human body? Explain your answer. 12. Create (draw) a table to compare and contrast the following respiratory agents: Streptococcus pneumonia, Listeria monocytogenes, and Mycoplasma pneumoniae for the 5 steps of the bacterial disease process (portal of entry. adherence, establishment, invasiveness, and portal of exit) (3 points)Explain how specialized structures (e.g., spore, capsule, fimbriae, or flagella) enable a microbe to survive in a given environment or contribute to pathogenesis.
- Construct at table to compare and contrast the 5 steps of microbial pathogenesis. How does extracellular growth differ from intracellular growth?1. Explain why pathogens need to attach to host cells. 2. Describe various microbial attachment techniques. 3. Describe the 5 steps involved in establishing infection. 4. Explain the modes of action for staphylococcal alpha toxin, cholera toxin, diphtheria toxin, Shiga toxin, and anthrax toxin. 5. Differentiate endotoxin from exotoxin. 6. Describe secretion systems used to export exotoxins/effector proteins. 7. Discuss the three main ways intracellular pathogens avoid intracellular destruction. 8. Describe various strategies pathogens use to avoid the immune system. 9. Describe mechanisms used by Listeria and Salmonella to establish infection in the host cellMicrobes and humans. 1. At what age is an individual considered to have their full complement of normal resident microbiota? 2. What is the host and their role in infection? 3. What host characteristics influence the development of infection? 4. Name several ways microbes can attach to host tissues/cells. 5. Name one antiphagocytic factor and how does it work?
- for each stage of pethogens explain how pathogens do expose the host tissue (exposure), then how to adhere the host tissue(adhesion), then explain how pathogens evade the host defense (inversion), at last explain causing damage to the host tissue (infection) Please help me!Describe three (3) methods by which pathogens are transmitted and give an example of each..Part B: Antifungal agents are less selectively toxic than antibacterial agents meaning that they cause more damage to the host cells. Why is that the case?
- i. What is Viroid how these viruses infect plant cells? How it differ from animal virus? iv. If you are asked to culture virus how it proceeds and which type of conditions will be needed to grow virus cells? v. Which type of sterilizing agents can be used in preservation of animals cells/tissues? How can we kill all types of microbes and which types of techniques can be used?Very often, the invasion of hosts by pathogenic microbes leads to infections. Discuss the different means microorganisms use to enter and colonize a host.a. During which stages of an infectious disease does the host exhibit signs and symptoms? Is there a correlation between this and when a disease is communicable? b. Why are some viral diseases, like smallpox and polio, no longer seen in the United States? Why are many bacterial disease, like syphilis, no longer a death sentence? Think about how these two types of microbes infect humans. Why might we make an effort to treat viral diseases before infection but continue to treat bacterial diseases after infection? c. Based on the graph below, which pathogen is more virulent: Agent 1 or Agent 2? Explain. 100 Agent 1 LD5 = 400, Agent 2 LD50 = 600 25 100 200 300 400 500 600 700 800 900 1,000 Dose (organisms administered per animal) Percent mortality 75
