Homework Answers
23. c. ergosterol.
Ergosterol is considered a possible target site for antifungals.
25. a. interferes with viral replication.
Complement activation makes the microbes to get out of the body cells. It has four main functions such as lysis of bacterial cell, activation of inflammation, opsonization, and immune response.
26. d. lack of specific receptor on the host cell.
The virus should have some sort of glycoprotein to attach with the host cell. Some viruses are resistant to the receptor of the host cell to attach.
24. e. C &d
T-cells dependent antigens involved in the interaction of specific antigen and indirectly activate helper T cells.
27 c. Enzyme development.
Antimicrobials normally deactivate the bacterial enzymes. Inactivation of antimicrobial agents leads to the development of enzyme development.
28. c. a protein made in response to an antigen that can combine with that antigen.
Antibodies are Y shaped protein that recognizes the antigen to combine and protects from harm.

You are a T-helper cell in your immune system and are deciding what parts of the immune system to marshall against an incoming invader. For this assignment, you will be presented with a pathogen and its arsenal of virulence factors that it can use against you. Your job, if you choose to accept it, is to pick the portions of the immune system that you will use against each virulence factor and then describe how that immune system part inactivates...
