-
A mature virus particle
virion
-
The nucleic acid is surrounded by a protien coat called a
capsid
-
A membrane (lipid-protein) derived from a host cell
envelop
-
Found only on enveloped viruses
spikes
-
Spikes are used for__and may cause hemagglutination
adsorption
-
A naked piece of nucleic acid that can be infectious is called
viroid
-
Viruses can be classified by
size, nucleic acid, morphology, and number of capsomeres
-
The capsid is composed of a number of protein units called a
capsomere
-
Viruses do not grow on
agar media
-
We grow viruses in
lab animals, embryonated eggs, a monolayer of cells, and bacterial cultures
-
In bacterial cultures, the growth of viruses will produce a clear area called
plaque
-
The ability of a virus to infect an organism is regulated by
host species, types of cells, attachment site, cell factors
-
A tadpole virus that infects bacteria
bacteriophage
-
A disease process occurs gradually over a long period of time
slow virus infections
-
Example of slow virus infections
rubella, scrapie, Creutzfeldt Jacob disease, Kuru
-
Remains in the host dormant after long period can produce disease
latent virus
-
Examples of latent viruses

Herpes Simplex I
-
Causes genital-chancroids
Herpes Simplex II
-
Cause of mononucleosis (kissing disease)
Epstein Barr Virus
-
Cause of chickenpox
Herpes zoster
-
-
-
Transmitted by sewage and flies
Poliovirus
-
In children, sore throat, vomit, rash, and abdominal pain
coxsackie
-
An arthropodborne virus, spread by insects (AEDES mosqito)
Arbovirus or Togavirus
-
Arbovirus causes
Yellow fever or Dengus fever or Beakbone fever
-

-
Rhabdovirus produces inclusion bodies in the cerebellum called
Negri bodies

Orthomyxovirus causes
influenza
-
Paramyxovirus causes
mumps
-
Hepatitis infects the__causing jaundice
liver
