Solved in 2 steps
- Which of the following amnong A-D is false concerning your microbiome? IS A) Ot represents a type of endosymbiosis B)O there are more of them on (and in) you than your own cells C) O they are generally (usually) harmless D) O you wvould be much healthier and happier if you did not have them at all 110All of the following are true about the normal microbiota of humans EXCEPT: They are important for resistance against infection by pathogens They are present in large numbers in the upper respiratory tract and mouth They are present in large numbers on the skin Some are transient and others permanently colonize the host They can be found throughout the body, including all internal organsCompare the relative abundance of Actinobacteria in the microbiomeof a healthy adult’s intestinal tract to that in a healthy stomach (see Figure 41.18). Suggest a possibleexplanation for why the microbiome composition in the two organs is different even though theintestine and stomach are directly connected.
- Propionibacterium acnes is a normal member of the skin microbiome that benefits the body by lowering the skin's pH- an antimicrobial effect. However, P. acnes is also the leading cause of acne. Explain mechanistically how can a bacterium be part of the normal microbiome and beneficial but also be pathogenic?Which of the following situations does NOT demonstrate the importance of a healthy microbiome? Group of answer choices Anthony suffers from debilitating diarrhea after a lengthy course of antibiotics to treat his MRSA infection. Andy is lactose intolerant. His body does not break down lactose, so the microorganisms in the gut do it for him. Mary suffers from colon cancer. While being treated, she develops an opportunistic Bacteroides fragilis infection. Jenna is prone to yeast infections, so she routinely eats yogurt and takes a probiotic supplement to increase the amount of lactic acid bacteria in her vagina.The gut microbiome directly benefits humans bydigesting complex carbohydrates and synthesizingvitamins and other nutrients. In what other ways domicroorganisms benefit humans?
- The best descriptive term for the resident microbiota is?Which of the following is NOT true of bacterial exotoxins? 1. Important in the pathogenesis of many human diseases 2. Their toxic effect can be systemic, affecting cells distant from the primary site of infection 3. None of the other four answers (All are true of bacterial exotoxins) 4. Different exotoxins may affect different types of cells (e.g., nerves, gastrointestinal mucosa) 5. Some exotoxins have two components, A (active) and B (binding)Which of the following is an example of a healthy microbiota that helps prevent infection from potentially pathogenic bacteria? Cytophaga Fusobacterium Leptospira Bacteroides Borrelia
- Microbiota In healthy humans, the internal organs and tissues such as muscles, the brain, and blood do not contain microorganisms. However, surface tissues, such as the skin and mucous membranes, are in continuous contact with environmental microbes and become readily colonized by specific bacteria. The population of microbes regularly found in the body is referred to as the normal microbiota. The term transient microbiota refers to members of the normal microbiota that are present for only a short time before disappearing. A person's normal microbiota is an important part of the immune system, as the normal microbiota often inhibit pathogenic microbes from colonizing the host, a process called microbial antagonism. Different types of bacteria will colonize different niches in a person's body due to variations in moisture level, pH. atmospheric pressure, oxygen levels, and body secretions. Accordingly, different types of medila must be used to culture the various human microbiota. If…Humans may carry both staphylococci and streptococci as normal microbiota. How might you easily differentiate between the two genera?Which of the following is a difference between transient and resident microbiota? Transient microbiota are pathogenic, and resident microbiota are not. Resident microbiota remain on the host for an extended period. Humans do not have transient microbiota. Transient microbiota can be opportunistic pathogens, and resident microbiota cannot. Resident microbiota cause disease and transient microbiota do not.
