Chapter 2, Problem 2.5SC
Summary Introduction
To examine: Whether the statement “C-section babies contain less diversity of microbiome in their gut as well as in their mom’s breastmilk” is true or false.
Introduction: A collection of all microbes that reside in all surfaces, including the body of a human, is called the microbiome. Microbiome includes bacteria, viruses, protozoa, archaea, and

Students have asked these similar questions
a.Explaination of how a bacteria must be present in all the cases of a disease.
b.explanation how a bacteria should be isolated from the infected organism and can be grown in pure culture.
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.

- Please help. The terms germ and microbe are often used interchangeably. What comes to mind when you hear the word germ?

Describe the benefits the microbe Bacteroides thetaiotaomicron provides to its host species. Helicobacter pylori was originally identified as a causative agent for ulcers in humans, but turns out its role is more complex. Describe how H. pylori also plays a role in regulating appetite.
