Complete Appendix C to differentiate among parasites, fungi, helminths, and arthropods.
Appendix C – Parasitology
After reading Ch. 11 in Microbiology: Principles and Explorations, complete the following matrices to compare and contrast different parasitic organisms. You may need to use the index to help you locate some of the information needed.
PROTOZOA/MASTIGOPHORANS
