This case presentation is intended to describe a bacterial infection in a cystic fibrosis patient. This exercise has been prepared for educational purposes only, and the informational content (i.e. symptoms and history) should not be used for diagnosis of cystic fibrosis or any other respiratory illness. The Biofilm Institute is not responsible for misuse of this information.


Students should be able to define a biofilm, describe the differences between biofilm (surface-attached) and planktonic (suspended bacterial cells) bacteria, and be able to describe why bacteria usually grow on surfaces.


Given each case example and web links to more information, the students will be able to answer the questions given and participate in discussion topics. Students will be able to apply their knowledge of biofilm characteristics and behaviors to the case discussion.


  1. Students will be provided with case information, beginning with Part I (II, III, IV).
  2. Students will be provided with Part I (II, III, IV) Questions.
  3. After answering the Questions, students will be prepared for Discussion.
  4. Discussion material can be used to supplement information gained by answering the Questions.


Does not apply to the case study.


Assessment of student understanding may be made by the instructor through examining answers to the Questions and also student ability to participate and contribute to the Discussion.


Does not apply to the case study.
