Textbook Question
Chapter 30, Problem 1COQ
Microbiomes occur in places that you may have not imagined. Starting with the term microbiome or microbiota, search the literature using a search engine such as Pubmed, Google Scholar, or BioOne, and identify microbiomes that you never knew existed. Discuss your findings with fellow students.

write an article on the role of the microbiome for human health: from basic science to clinical applications
go to the website https://www.nature.com/immersive/d42859-019-00041-z/index.html and scroll up and down to review the milestones associated with microbiota research. Answer the questions/ prompts below.
Bacteria and our brain? Read the information associated with this milestone and what was discovered. Briefly describe what they found...Milestone/year?
What milestone is associated with the debate about when the microbiome is first established? Why is there a debate? Watch the video just below the milestone.
What specific type of gene analysis was used to determine that we have our own unique microbiome? Which milestone/year?
Sometimes we need antibiotics...this milestone discusses how long it can affect us after infection. In this milestone they discussed how long we could be affected by one course of antibiotics...how long? Which milestone/year?
Find the milestone associated with a highly motile bacteria. What disease was treated? How was this treatment used for a…
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.

Question options: The transient microbiota and genetic material of a person The resident microbiota and genetic material of a person The transient microbiota of a person The transient and resident microbiota of a personarrow_forwardIdentifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.arrow_forwardAsaparrow_forward

- A student argues that it makes no sense to be concerned about coliforms in drinking water because they are harmless members of our normal microbiota. Explain why regulatory agencies are concerned about coliforms.arrow_forwardChoose the false statement: (Regarding Pasteur’s famous experiment) The swan necked flasks were important because they allowed the broth to remain sterile, while still remaining open to the atmosphere. Pasteur’s work with the swan neck flasks was only of importance to the food industry; his work occurred long before anyone, including Pasteur, had any awareness that diseases could be caused by microscopic agents. The swan necked flasks were used to prove that life could only arise from pre-existing cells.arrow_forwardMicrobiota 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…arrow_forward
- Robert Koch developed a set of criteria (postulates) for conclusively demonstrating the aetiology (specific cause) of an infectious disease. Which of the following is not a postulate?
