The presence of microbes in a host is not always synonymous with infections
Can you describe the different kinds of relationships that bacteria may establish with their host in detail?
Step by step
Solved in 2 steps
- When virulent bacteria invade an organism, they usually inflict damage to it. Can you assess the different means a bacterium may use to affect the integrity of the host in detail?Normal microbiota provide protection from infection in each of the following ways EXCEPT: Question 3 options: A) they produce antibacterial chemicals. B) they compete with pathogens for nutrients. C) they make the chemical environment unsuitable for nonresident bacteria. D) they produce lysozyme.1. Mucous membranes are barriers against colonization and growthof microorganisms. However, mucous membranes, for examplein the mouth and gut, are colonized with a variety of differentmicroorganisms, some of which are potential pathogens. Explainhow these potential pathogens are controlled under normalcircumstances. Then describe at least one set of circumstances thatmight encourage pathogenicity.
- Match descriptions with terms. Some choices may be used more than once, and others not at all. Microbes in this part of the body probably arrive by fecal-oral transmission. The airway, gastrointestinal tract, and genito-urinary tract are lined with this Skin microbes plus microbes in this location on the body comprise the normal flora Pathogens in this location are invasive. A. raw eggs B. gastrointestinal tract C. blood D. mucosal surfaces E. there is no such location1. What are the additional parts of a bacterium needed for infection of host? Answer this completely and please, do not just copy from somewhere?Describe two mechanisms that bacteria use to invade via mucous membranes.
- is bacterial infection same as bacteria toxin?To prevent superinfections, a treatment plan should target only the bacteria causing the initial infection. increase the growth of the host microbiota. target gram-negative and gram-positive bacteria. cause wide-spread denaturing of proteins. eliminate all bacteria in the host.1. Identify organs in the human body that are normally colonizedby microorganisms. Which organs are normally devoid ofmicroorganisms? What do the organs in each set have in common?
- Microbes 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?What is the “iceberg concept of infection.” How does this affect our understanding of the mortality rates of a particular microbe?Functionally, normal microbiota is beneficial to it's host organism and on the other hand, it may cause harm, How does this normal microbiota cause harm? Explain briefly but acurately
