Exam 66: Antiviral Therapy, Susceptibility Testing, and Prevention

Match the virus with the appropriate antiviral agent. -Amantadine

If a physician prescribes Tamiflu to a patient, the patient is most likely infected with which virus?

Point mutations in the hemagglutination (HA)or neuraminidase (NA)genes during viral ribonucleoprotein (RNP)replication give rise to new strains.This mechanism is known as the antigenic:

Which type of assay uses a variety of endpoint measurements to determine whether the virus is inhibited by the antiviral drug or is demonstrating drug resistance?

In the 1920s, an instrument known as an "iron lung" was developed to fight breathing difficulties associated with which infection?

Match the virus with the appropriate antiviral agent. -Lamivudine

Match the virus with the appropriate antiviral agent. -Acyclovir

MATCHING Match the assay with its function. -Inhibits viral plaque formation.

When performing antiviral susceptibility testing, a standard inoculum must be used.If the inoculum quantity is too large, then the isolate will appear:

At the end of the 2008-2009 influenza season, 100% influenza A H3N2 and the novel 2009 influenza A H1N1 were resistant to:

The only virus that has been globally eradicated is:

Match the virus with the appropriate antiviral agent. -Saquinavir

MATCHING Match the assay with its function. -Viable cells take up neutral red dye.

MATCHING Match the assay with its function. -Quantifies sequence variation.

MATCHING Match the assay with its function. -Quantifies the amount of viruses infected in cells.

Match the virus with the appropriate antiviral agent. -Ribavirin

The recombinant virus assay (RVA)uses which type of amplification methodology?

MATCHING Match the assay with its function. -Inhibits viral DNA synthesis.
