Flashcards in W3-4 Viral, Fungal, and Parasite Pathogenesis Deck (11):
1

Group IV virus type

+ssRNA

2

Hepatitis C

Group-Family

Group IV-Flaviviridae

3

T/F HepC has a tegument portion

F

4

Host response mechanism to Class IV viruses

5

What if dsRNA is detected inside the cell?

RIG-I recognizes it from surface of mitochondria and initiates idential response as TLR3

6

NS3/4 A

Protease-ctivates viral proteins

Deactivates TLR3 and RIG-I defense mechanisms

7

Viral disease mechanisms

1. Cytopathic effect: disrupts physiology

2. Host immune response: causes illness

3. Tumorigenesis: uncontrolled proliferation

(HPV)

8

Fungi disease mechanisms

1. Overgrowth

2. Host immune response

9

Protozoa disease mechanisms

1. Displacement

2. Cytopathic: disrupts normal physiology

3. Host immune response

10

Helminths disease mechanisms

1. Displacement

2. Competition: nutrients with host

3. Host immune response
