- Identify the locations and some major genera/groups of normal microbial flora, specifically: enterobacteriaceae (such as E. coli), Bacteroides, Staphylococcus (genus), Staphylococcus aureus, Micrococcus, Candida, Streptococcus, Neisseria, Haemophilus.
- Describe all the sites that normally harbor microbial flora as "internal" or "external".
- Describe how normal flora is initially acquired.
- Explain the major roles of normal microbial flora and provide examples of ways in which normal flora impact nutrition, behavior, immune health, and organ development.
- List three ways normal flora protects from infection.
- Briefly describe the roles of short chain fatty acids (SCFAs) and serotonin in the "dialog" between the microbiota and human body.
- Describe two mechanisms by which the activity of gut microbiota can impact human metabolic physiology (available calories, blood sugar, blood lipids).
- Compare and contrast: primary and opportunistic pathogens, endogenous and exogenous infections.
- Explain how the normal flora can act as a source of pathogens and be able to provide examples.
- Explain why use of broad-spectrum antibiotics can lead to superinfections.
