Textbook Question
Chapter 13, Problem 1CTQ
Based upon data from the Human Microbiome Project (HMP):
- a. Provide evidence in support of or refuting the following statement: Babies are born sterile.
- b. Define microbial antagonism, and discuss how the various microbial populations keep each other “in check.” with consequences for human health.

An advantage of a point-of-care (POC) test is that
effective antibiotic therapy can begin without a delay of waiting for off-site
laboratory results.
detection of multiple infections is more likely.
clinicians are able to diagnose diseases based on clinical signs and symptoms
alone.
health care workers have a lower risk of exposure to pathogens.
What are three public health measures that could reduce the probability that bacteria will develop resistance to antibiotics? Be specific in your description, and remember to include evidence to support your answer.
Choose the false statement below.
Resident microbes in our gastrointestinal tract assist in our immune system's ability to recognize
future emerging infections that may be created by gene transfer into species of normal body
flora.
The Human Microbiome Project goals included examination of ethical implications of collecting
data on the human microbiome as well as development of techniques to create new vaccines.
Animals grown in the absence of bacteria provide evidence for the role of normal body flora in
development of the digestive and immune systems.
Question 15
Choose the false statement below.
An unborn baby is axenic but, upon delivery, acquires body flora via both oral and vertical
transmission but also via direct transmission from healthcare workers.
O The many species that provide humans with bacterial antagonism are also considered
opportunistic pathogens.
Unlike opportunistic pathogens, a true pathogen causes disease no matter how much inoculum
is introduced into the host.
