Capsid
Protein coat of a virus
Envelope (Not for Mail)
Layer of phosopholipids and proteins surrounding the protein coat of some viruses.
Bacteriophage (Phage)
A virus that infects bacteria
Host Range
The kinds of organisms or cells that a virus can infect.
Reservoir (Virus)
A host species that serves as a continual source of viral infection for other species
Lytic Infection
Type of infection in which a bacteriophage enters a cell, replicates, and causes the host cell to burst (lyse) as it releases the new viruses
Lysogenic Infection
Type of infection in which the genetic material of a bacteriophage is replicated along with the host cell’s chromosome
Prophage
DNA of a lysogenic bacteriophage that is inserted into a host cell’s chromosome
Virus
An infectious agent consisting of genetic information enclosed in a protein coat.
Latent Infection
In animals, a viral infection in which viral genetic information replicates along with the host genome, but infected cells do not immediately produce new viruses; when the infection is reactivated, infected cells begin producing viruses.
Virulence
The degree to which a virus, bacterium, or other pathogen harms its host
Vaccine
A substance that initiates a primary immune response to a pathogen without actually causing a disease
Viroid
Infectious RNA molecule
Prion
Infectious particle composed of protein
