Virus? Bacteria? Parasite?

Virus Must Haves:  Viruses require a host to replicate  Extracellular state  Intracellular state  Viral life cycle:  Attachment  Entry  Replication  Assembly May Haves:  Beneficial or pathogenic  DNA or RNA  Single or double stranded  Animal, plant, or bacteriophage  Rod-shape or spherical

Virus Influenza VirusViral Structure (DNA or RINA)

Bacteria Must Haves:  Unicellular  Prokaryotes  Smallest living organisms .1-10um  High surface area to mass ratio  Binary Fission May Haves:  Pathogenic and beneficial  Response to oxygen  Aerobic  Anaerobic  Facultative anaerobes  Energy consumption/production  Heterotrophic  Autotrophic  Taxonomy  Eubacteria  Archaebacteria

Bacteria Eubacteria, Archaebacteria Cocci, Bacilli, Spirilli

Parasite  Eukaryotes  Live in or on a host  Obtain food from host May Haves:  Three main parasites that cause disease in humans  Protozoan  Helminths  Ectoparasites Must Haves:

Ectoparasite Helminth Protozoan

Treatment and Complications: The “So What?” Antimicrobial Resistance What is it? What causes it? What effect does it have on disease persistence, communicability, and fatality?
