rhinovirus

17

What is the heparnavirus of the picornaviradea family?

hepatitis A virus

18

What is this:
naked (N), small, icosahedral (ICO) capsid enclosing (+) ssRNA genome

Picornaviruses

19

(blank) are resistant to ph 3-9, detergents, sewage treatment and heat.

Enteroviruses

20

(blank) are labile at acidic pH; optimum growth is 33 degrees celcius

Rhinovirus

21

What is the genome of the picornaviradae and what does this mean?

it is mRNA (infectious without capsid)

22

Where does the picornaviradae repicate?

in the cytoplasm (most RNA viruses)

23

During replication, what does Picornaviradae create?

polyprotein produced from viral RNA genome

24

Viral encoded (blank) is essential for repliction of RNA viruses in the cytoplasm

RNA-dependent RNA polymerase

25

RNA-dependent RNA polymerase (needs/does not need) to be included in the virion for (+) sense RNA viruses?

Does not need

26

How is the picronaviridae enterovirus poliovirus transmitted?

by fecal-oral route

27

T or F
Paralytic polio remains high in developing countries
Only 1% of infections are clinically apparent

T

28

Where do you initially have replication of the polio virus?

oropharynx and small intestine (causes nausea and vomiting)

29

How can the polio disease appear?

disease range from asymptomatic to paralytic poliomyelitis

30

What is poliomyelitis

an acute viral infection of the meninges and the motor neurons of the spina cord and brainstem
