CIC Exam 2024 Questions with
Complete Solutions3
What is an essential element from the environment that many bacteria concentrate which
enhances virulence factors for growth and toxin production? - ANSWERS-Iron
Phagocytosis - ANSWERS-Pathogen interacts w/receptors on the phagocyte. The phagocyte
envelopes the pathogen. Lysosomes make intracellular very acidic and digest the pathogen.
Then presents some of the pathogen's material on the outside of the cell to become antigen-
presenting cell. Now has specific immunity to the pathogen.
Lysozme - ANSWERS-A powerful antimicrobial substance produced by the mouth, eyes, and
intestines. Works against gram-positive bacteria by degrading peptidoglycan in their cell walls.
Pattern Recognition Receptors (PRRs) - ANSWERS-Type of protein receptors on/in immune and
other types of cells which allow cells to recognize pathogens and damaged cells. This triggers
the cell to release inflammatory chemicals triggering an immune response.
What are examples of bacteria that have evolved to not only survive the phagocytic process, but
to replicate inside phagocytes? - ANSWERS--Mycobacterium tuberculosis
-Listeria monocytogenes
-Legionella pneumophila
Which cells are the principal antibacterial PMNs (granulocytes) and the first to arrive at the site
of an inflammatory focus? - ANSWERS-Neutrophils
