Exam 6: Viruses and Prions

An individual uses an in- home test kit one week after engaging in high- risk behavior for HIV infection. The test kit uses a saliva sample that is mailed to a lab where an agglutination test to detected HIV antibodies is run. The results come back negative for HIV. What should the patient consider regarding these test results?

Which suffix denotes the "order" level of classification for viruses?

During lytic replication of bacteriophage, which process uses factors from the host cell, rather than coded by the viral genome?

Which statement is not true about chronic persistent viral infections?

Oncogenic viruses

HIV, the virus which causes AIDS, interacts with two receptors on the host cell membrane: CD4 and CCR5. A small percentage of individuals have a genetic mutation which causes their cells to lack CCR5. These individuals will never develop AIDS nor are they able to pass HIV on to others. Which part of viral replication is being blocked by the lack of a receptor?

Both agglutination and ELISA procedures may be used to detect the presences of either viral antigen or the patient's antibodies to a virus.

The number of species that a specific virus infects is called its host range while the types of tissues that the virus infects is called tropism.

Which of the following prion diseases may be acquired by eating beef contaminated with a cattle prion?

Animal viruses can be grown in all of the following except

Challenges in developing effective antiviral drugs with minimal side effects to the patient include

Viral spikes

Which stage of animal virus replication will not be different between naked viruses and enveloped viruses?

Phage conversion occurs when

Which of the following antiviral drug categories is incorrectly matched with its description?

All viruses must use their genome to produce , which is then used by the host cell to produce .

Viruses are considered to be non- living pathogens for which reason?

Which of the following are contributors to viral genome evolution?

Which stage of viral replication is shown?

Viruses which infect many different tissues types are said to have a(n)
