Learning Objectives for "Quorum Sensing, Pathogenicity Islands, and Secretion Systems"
After completing this section you should be able to perform the following objectives.
1*. Define the following:
a. pathogenicity
b. virulence
2. Even though a microorganism may be considered pathogenic, it still may not be able to cause disease upon entering the body. Discuss why.
3**. Define and briefly describe the overall process of quorum sensing in bacteria how population density may enable bacteria to behave as either individual bacteria or as a multicellular population.
4*. State at least two possible advantages of individual bacterial behavior.
5*. State at least two possible advantages of multicellular bacterial behavior.
6. State what is meant by intraspecies, interspecies, and interkingdom communication.
7*. State the function of bacterial secretions systems (injectisomes) such as the type 3 and type 6 secretion systems in bacterial pathogenicity.
(*) = Common theme throughout the course
(**) = More depth and common theme
