Ch. 19 + 40 Flashcards
Protein coat of virus fits with protein of host cell
Identification/Recognition
Viral DNA injected into host cell
Injection
WBC that eat pathogend
Macrophage
Chemical released by activated mast cells that increases the flow of blood and fluids to the surrounding area
Histamine
Viral DNA takes over host DNA. Viral nucleic acid and protein coats made
Reproduction
Substance that triggers an immune response
Antigen
Acidic, wash away infection, nonspecific
Sweat
Disease-causing agent
Pathogen
One of a group of proteins that help cells resist viral infection
Interferon
Ability of the body to resist a specific pathogen
Immunity
A short hairlike projection, produces movement in many cells
Cilia
Elevated body temperature that occurs in response to infection
Fever
The organism infected by the pathogen
Host
Protein that helps destroy pathogens
Antibody
The host cell burst releasing thousands of new viruses into the host to attack new cells
Lysis
Particles of nucleic acid, protein, and in some cases lipids that can replicate only by infecting living cells
Virus
Made in bone marrow, mature in bone marrow, produce antibodies
B-Cell
Reads the antigen displayed on the surface of the macrophage
Helper T-Cell
Virus parts put together
Assembly
A preparation of weakened of killed pathogens
Vaccine
Virus that contains RNA as its genetic information
Retrovirus
Virus that infects bacteria
Bacteriophage
The viral DNA that is embedded in the host cell’s DNA
Prophage
Short-term immunity caused when antibodies produced by other animals for a pathogen are injected into the body
Passive Immunity
