|
What are prions? page 76 |
Modified host protiens. |
|
What are viruses? page 76 |
Infectious agents that rely on the hosts metabolic machinery for replication. |
|
What are Bacteriophages, Plasmids and Transposons? page 76 |
Mobile genetic agents that infect bacteria making them either more virulent or more resistant to antibodies |
|
What are bacteria? page 76 |
Single cell organisms that lack a true nucleus, carry only one circular chromosome, have a cell wall & membrane, multiply by binary fision and are classified as either: Cocci (round), Bacilli (rod) and Spirochetes (spiral) |
|
What are Rickettes, Chlamydiae, Mycoplasmas? page 76 |
Transmitted mostly by insects, these are like bacteria but missing certain structures or organelles. |
|
What are Fungi? page 76 |
Produce spores, asexual at times. |
|
What are Protozoa? page 76 |
Mobile, single cell organisms that replicate within the cell or urogenital system, intestines or blood. Tranmitted via fecal-oral route or by blood sucking insects. |
|
What are Helminths? page 76 |
Parasitic worms |
|
What are Ectoparasites? page 76 |
Bugs that attach to and live on the skin. (ie Bed bugs) |
|
Define Pathogenecity. page 77 |
The ability of the infectious agent to establish itself in a host and cause disease. |
|
What is Virulence? page 77 |
The measure of strength of pathogenecity |
|
Describe Low Virulence. page 77 |
Relies on person to person contact to spread. |
|
Describe high virulence. page 77 |
Can be spread by many means. |
|
What are Virulence Factors? page 77 |
The ability of the organism to produce symptoms. |
|
What are Pili? page 77 |
Appendages that allow bacteria to adhere to mucosal surfaces. |
|
What are Toxins (regarding virulence factors) ? page 77 |
Potent molecules secreted or released from bacteria. |
|
What is a cell capsule? page 77 |
Protective outer surfaces that allow bacteria to avoid phagocytosis by non specific host defenses. |
|
What is an Infective Does? page 77 |
The number of bacteria required to causes disease. |
|
What are some ways that Infectious Agents cause disease? page 77 |
Kill hosts cells directly |
