Mnemonic for the DNA viruses
HH-A-PPPP-y Herpes Hepadna Adeno Papilloma Polyoma Parvo Pox
All DNA viruses have dsDNA genome except…
Parvovirus = ssDNA
All DNA viruses have icosahedral capsids except…
Poxvirus = complex
Name the 2 major polyoma viruses.
JC virus - C = cranium
JK virus - K = kidney
Mnemonic for picornaviruses
PERCH Polio Echo Rhino Coxsackievirus Hep A
Where do most RNA viruses replicate in host cells? Name notable exceptions.
Most replicate in cytoplasm
Exceptions - those w/ nuclear requirement
- Flu
- HIV
Mnemonic for ssRNA viruses
"Call Pico and Flo to Come Rightaway" Calicivirus Picorna Flavivirus Toga Corona Retro (Arranged smallest --> largest)
All negative sense RNA viruses have what 2 things? Mnemonic to remember the -ssRNA.
Helical capsids Envelopes "Always Bring Polymerase Or Fail Replication" Arena Bunya Paramyxo Orthomyxo Filo Rhabdo
Mnemonic for segmented RNA
BOAR Bunyavirus Othromyxovirus Arenavirus Reovirus
Mnemonic for viruses causing diarrhea
ACNE CAR Adeno Carona Noro Entero Calcivirus Astro Rota
Mnemonic for maternal infections that can cross placenta and cause congenital abnormalities
ToRCHeS TOxoplasmosis Rubella Cytomegalovirus Herpes & HIV Syphillis
What are the 4 general structures a virus can be/have?
- Naked = iscosahedron capsule
- Icosahedron capsule inside envelope
- Protein helix inside envelope
- Complex
Describe characteristics of naked viruses.
Stable Released from host via cell lysis Spreads easily Symmetry Ab immunity likely to be enough
Describe characteristics of enveloped viruses.
Labile - easily broken down, must stay wet
Released via budding off host cell membrane
Likely to need Ab & cell mediated immunity
Give the endings for order, family, sub family, and genus of viruses.
Order = -virales Family = -viridae Subfamily = -virinae Genus = -virus
