Virology Flashcards
cytopathic effect
cell damage from virus
Virion
ss nucleic acid with capsid protein coat
Nucleotide reverse transcriptase inhibitors
DNA blocked with primer
AZT
prevent synthesis by binding to base stopping chain
Antiviral agents
formaldehyde, metals, lipids, UV, phenol/halogen, heat
Replication
adsorption/attachment, penetration, uncoating, synthesis, assembly, release
transformation
cell get fucked up, oncovirus (HIV/HPV)
inclusion
Negri body (rabies in neuron), Cowdry body (HSV/VZV)
syncytium
giant multinucleated cell, RSV/HIV/rubeola
Virus culture
