Bacterial endospores function in A. reproduction B. nutrient storage C. protein synthesis D. survival 3. Which bacterial structure is not composed primarily of protein in most cases? A. gas vesicles B. fimbriae C. flagella D. capsule 4. Which of the following is not considered a function of bacterial capsules and slime layers? A. protection from host defenses B. survival at high temperatures C. attachment to surfaces D. prevent desiccation 5. A. Name 4 structures that are present in almost all bacterial cells. B. Name 6 structures that are present in some but not all bacteria. What are the functions of these structures? 6. Name two of the structures in part B, above, which contribute to an organisms ability to cause human disease. Explain how each structure may help an organism cause disease. Without using a microscope, how might you demonstrate that an organism produces bacterial endospores? 8. What clinically important genuses of bacteria produce endospores? Why are these organisms difficult to deal with in a healthcare setting?
