Virus stuff Flashcards
Anti-HBs + Anti-HBe + Anti-HBc IgG
Recovery
Immunized to HBV serum
Anti-HBs
DNA hepatitis virus
Hep B
(All others are RNA)
Where does CMV stay latent?
Mononuclear cells
Chronic phase serum with low infectivity
HBsAG
Anti-HBe
Anti-HBc IgG
Which DNA viruses are not linear?
Papilloma
Polyoma
Hepadna
Which DNA virus does not replicate in the nucleus nor has an icosahedral capsid?
Pox virus
(remember it’s the largest virus = can carry its own DNA-dep RNA polymerase)
Owl eye inclusions
CMV
Waterborne epidemics, hepatitis
HEV
Requires another virus
HDV requires HBV
HBsAG + Anti-HBe + Anti-HBc IgG
Chronic infection with low infectivity
Roseola infanatum
Fecal-oral hepatitis viruses
HAV
HEV
How do anti-HBV antibodies protect against hepatocellular damage?
Antibodies prevent viral entry into cells, so antigens can never be loaded onto MHC class I and presented to CD8+
Hepatits that’s usually asymptomatic
HAV
DNA hepadnavirus
HBV
Worse prognosis HDV
Co-infection with HBV
ssDNA virus
Parvovirus
Measles
Chronic HBV serum with high infectivity
HBsAg
HBeAg
Anti-HBc IgG
Anti-HBe + Anti-HBc IGM
Window period (5-6 months after infection)
High fevers for several days that can cause seizures followed by a maculopapular rash
Roseola (HHV-6)
Which virus gets its envelope from the nuclear membrane?
Herpesviruses
(All other enveloped virus get it from cytoplasmic membrane)
