Question
Chapter 12, Problem 18Q
Summary Introduction
To explain:
The reason of presence of microorganisms or their DNA in the white blood cells (WBC) rather than red blood cells (RBC), also explain the role of microorganisms in the blood cells.
Concept introduction:
Microbiome refers to the group of microorganisms present in a particular environment, especially inside the human body. The microorganisms present may be
RBC and WBC are the major component of the blood. RBC (lack nucleus) contain an iron group that caries oxygen, whereas in WBC the nucleus is present and the serves as major cells of the immune system.

The human microbiome is an integral part of human health. Unfortunately, the microbiomes of Americans are reduced in species diversity relative to those of people in other countries, especially those living in non-Western countries. Give examples of three beneficial functions that the human gut microbiome provides to us, the host and what are three potential causes of the reduced gut microbiomes of Americans? Part II: What are three potential consequences of the reduced gut microbiomes of Americans?
Because of overuse of antibiotics and/or weakened governmental surveillance of infectious disease, several diseasesthat had been thought to be no longer a threat to humanhealth (e.g., pneumonia and tuberculosis) are rapidly becoming unmanageable. In several instances, so-called superbugs(microorganisms that are resistant to almost all known antibiotics) have been detected. How did this circumstancearise? What will happen if this process continues?
Is the human gut microbiome contains trillions of microbes that both influence and are influenced by emotional and cognitive areas of the brain?

- Our environment contains masses of microorganisms, many of which reside as commensal organisms on our body’s mucosal and epithelial surfaces without causing disease. What two features distinguish a pathogenic microbe from these commensal microbes?arrow_forwardWhich of the following statements is incorrect? a. Mucosal surfaces are better than skin surfaces at supporting colonization by commensal microorganisms. b. The skin provides a larger surface area than mucosal surfaces for commensal microorganisms. c. There are ten times as many bacteria residing in the intestinal tract than the number of cells in the human body. d. It is common for commensal bacteria to live in symbiosis with their human hosts. e. During gestation in mammals, a fetus does not have any commensal microorganisms on their skin or mucosal surfaces.arrow_forwarda. 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.

Choose one or more: A.A capsule that, when thick, will help the organism avoid phagocytosis by macrophages B.A cell wall containing lipoteichoic acid, thought to facilitate adherence to pharyngeal epithelial cells C.Enzymes that lyse blood cells (streptolysins) D.The production of several endotoxins called streptococcal pyogenic endotoxins (SPEs)arrow_forwardWhich of the following amnong A-D is false concerning your microbiome?

- Pathogenic infections induce damage to the host by a variety of mechanisms. While many mechanisms are direct effects of the pathogen, some damaging mechanisms result from the immune response to the infection. Examples of damage caused by the host immune response are: a) Exotoxin production, endotoxin b) Cell-mediated inmunity, direct cytopathic effect c) Endotoxin, inmmunune complexes d) Direct cythopathic effect, endotoxin e) Cell-mediated inmunity, inmmunune complexesarrow_forwardDuring the anthrax crisis of 2001, public health officials urged citizens not to take the antibiotic ciprofloxacin as a preventative measure. Public health officials were concerned that overuse of ciprofloxacin would lead to resistant varieties of anthrax and other bacterial pathogens. Ciprofloxacin is one of the few readily available antibiotics that can treat anthrax. 1)Do you think that public health officials should more directly regulate the availability of ciprofloxacin to ensure its proper use? 2)Why?arrow_forwardIn 1969, a 16-year-old boy named Robert Rayford was admitted to a hospital in St. Louis, Missouri. He was weak, emaciated, rife with stubborn infections, and riddled with rare cancerous lesions known as Kaposi’s sarcoma, a skin disease found in elderly men of Mediterranean descent. Three months after he was admitted, he died of pneumonia. More than ten years later, similar cases were seen in states like New York and California. It was eventually discovered that young Robert Rayford actually had AIDS. Using 2-3 pieces of evidence from the text, explain why Robert Rayford ended up dying from pneumonia.arrow_forward
- It was not until 1928 that penicillin, the first true antibiotic, was discovered by Alexander Fleming, Professor of Bacteriology at St. Mary's Hospital in London. Penicillin heralded the dawn of the antibiotic age. Before its introduction there was no effective treatment for infections such as pneumonia, gonorrhea or rheumatic fever. Hospitals were full of people with blood poisoning contracted from a cut or a scratch, and doctors could do little for them but wait and hope. 1. What is the mechanism of action of penicillin? 2. Cells treated with penicillin do not die immediately, so how this antibiotic is effective? 3. Why penicillin is most effective against Gram-positive bacteria? 4. Explain penicillin resistance mechanisms among bacteria today and the causes why they gained this resistance and making this great life-saving drug not usable anymore.arrow_forwardIn this Module you learned that bacteria are everywhere. You watched several videos and read an article about all the ways in which the microbiome can be connected to the health of different parts of your body. 1. Based on the content in lecture and your readings, explain the connection between your microbiome and your health (use 2 specific examples)? 2. Describe one major way your microbiome can be altered in a negative way? 3. Describe two ways you can improve your gut microbiome? For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
