VIrus Module Set 7

QuestionAnswer
host cell damage and cell death: inhibition of host DNA, RNA, and protein synthesis
host cell damage and cell death by lysosome damage causes release of hydrolytic enzymes into cell
host cell damage and cell death by alteration of plasma membrane can lead to attack of host cell by immune system cell fusion, forming syncytium
host cell damage and cell death by toxicity from high concentrations of viral proteins
host cell damage and cell death by formation of inclusion bodies, which can disrupt cell structure
host cell damage and cell death by chromosomal disruptions
host cell damage and cell death by transformation of host cell into malignant cell
acute infections: rapid onset and relatively short duration
persistent infections: can last many years
chronic virus infection: virus... almost ALWAYS detectable
chronic virus infection: during latency... symptoms, antivirus-antibodies, and viruses are NOT detectable
cause of persistent infections by integration of viral genome into host genome
cause of persistent infections by decrease in antigenicity of virus
cause of persistent infections by mutation to less virulent and slower reproducing form
defective interfering (DI) particle: deletion mutant that CANNOT reproduce and slows reproduction of normal virus
