virulence
|
|
a virus of reduced virulence that has accumulated so many mutations in pathogenic genes that it can not cause disease
|
avirulent/apathogenic strain
|
|
individuals who have never been exposed to any form of the virus leading to an immune response

palliative treatment
|
|
SARS
|
severe acute respiratory syndrome
|
|
an inflammation of the brain or tissues of the upper CNS
|
encephalitis
|
|
a group of proteins (cytokines) secreted by virus-infected and certain other cells that act to induce a specific set of cellular antiviral and intitumor responses in other cells
|
interferons (IFN)
|
|
a DNA virus replicating in the ovaries of certain parasitic wasps that can suppress the immune response of the caterpillar prey to the developing wasp embryo

prophylactic
|
|
the smallest/simplest pathogen able to control self-replication in a host cell; an infectious agent spread by ingestion that does not appear to contain any genetic material
|
prion
|
|
virus particles that are normal in appearance but cannot initiate a productive replication cycle
|
defective virus particles
|
|
a virus in a mixed infection (usually in cultured cells) that provides a complementing function so that a co-infecting defective virus can replicate
|
helper virus
|
|
a plant pathogen that is the smallest known nucleic acid-based agent of infectious disease
|
viroid
|
|
an infectious agent spread by indigestion that does not appear to contain any genetic material; cellular proteins with an unusal folding manner
|
prion
|
|
a slow, noninflammatory infection of the human CNS caused by a prion
|
Creutzfeldt-Jakob disease (CJD)
|
|
any infection that results in the production of more infectious virus at the end than at the start
|
productive infection
|
|
the actual number of infectious viruses produced in an infected cell; ranges from 10- 10,000
|
burst size
|
|
ability of certain bacteriophages to integrate its genome into that of the host bacteria and remain associated as a genetic passenger as the bacteria replicate
|
lysogeny
|
|
the alteration of a cell by inseertion of one or more foreign or mutant genes
|
transformation
|
|
HSV
|
herpes simplex virus

|
reservoir
|
|
the agent or means by which an infectious agent is spread from one individual to another
|
vector
