In order to receive full credit (10 pts) for the assignment, students need to answer all parts of the question and provide support for each part of the answer.

This usually requires a minimum of four to six sentences per question, though questions with multiple parts may require a longer answer in order to be complete. The response may source the textbook or another credible source (with citation) to justify their answer (at least two reference).

1. 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.

2. Compare and contrast the terms bactericidal and bacteriostatic in relation to microbial control agents. Develop a simple experimental method that could be used to test whether a control agent exhibits bactericidal or bacteriostatic effects.
