Learning Objectives for "Prokaryotic Cell Anatomy: The Gram-Positive Cell Wall"

After completing this section you should be able to perform the following objectives.

1*. State what color Gram-positive bacteria stain after the Gram stain procedure.

2**. Describe the composition of a Gram-positive cell wall and indicate the possible beneficial functions to the bacterium of peptidoglycan, teichoic acids, and surface proteins.

3*. Briefly describe how PAMPs of the Gram-positive cell wall can promote inflammation.

4*. State the function of bacterial adhesins, secretion systems, and invasins.

5*. Compare and contrast innate immunity and adaptive immunity.

6*. Define antigen and epitope.

7*. Define humoral immunity and cell-mediated immunity.

8*. Briefly describe how opsonizing antibodies can promote phagocytosis and how antibodies made against cell wall adhesins can block colonization.

(*) = Common theme throughout the course

(**) = More depth and common theme

Highlighted Bacterium

1. Read the description of Enterococcus, and match the bacterium with the description of the organism and the infection it causes.
