Bunyaviridae Flashcards
Bunyaviridae is characterized by all of the following EXCEPT:
A. Spherical, enveloped virions
B. Glycoprotein spikes and matrix proteins
C. Segmented, negative, ss RNA
D. 3 RNA and nucleocapsid segments with helical symmetry
E. All of the above are correct
B
NO matrix protein
Yes, GP spikes
I got 3 bunyons on my foot (3 nucleocapsid segments, 3 RNA segments) and its a negative thing to have 3 bunyons (negative sense). And it feels like spikes are poking into my feet! I can’t do Matrix moves like this! (No matrix)
T/F:
Virions of Bunyaviridae bud through the ER.
False!
They bud thru the Golgi
Golgi sounds like some kind of ointment you would use for bunyons
T/F:
Bunyaviridae is known to be able to do reassortment because it has a segmented RNA genome.
True!
T/F:
Most genera of Bunyaviridae are arthropod-borne, except Hantavirus.
True
Phlebovirus is known as what and has what for its primary biological vector?
A. Rift Valley Fever; Culex and Anopheles
B. Akabane Virus; Aedes spp
C. Akabane Virus; Culex and Anopheles
D. Rift Valley Fever; Aedes
D
Phlebovirus epizootic cycle is characterized by what?
A. Increase in transovarial transmission in Aedes (primary) vectors
B. Heavy rainfall
C. Involvement of Anopheles and Culex vectors (secondary vectors)
D. Abortion storms in livestock
E. All of the above
E.
Phlebovirus is characterized by what lesions/findings?
A. Hepatic necrosis B. High mortality in young lambs C. hemorrhages and shock D. Abortion storms E. All of the above
E
T/F:
Akabane Virus is a member of the genus Phlebovirus and is a major cause of congenital disease in sheep, goats and cattle.
False
Genus Orthobunyavirus
I think about it causing the arthogryphosis which is the stiff joints and they thus have trouble being delivered and ortho also means joints
T/F:
Both Rift Valley Fever Virus and Akabane Virus can be transmitted via Culicoides spp.
True
Akabane Virus is characterized by which congenital defects? A. Arthogryphosis B. Hydranencephaly C. Polymyositis D. Encephalomyelitis E All of the above
E
T/F:
Akabane Virus is reportable.
True
T/F:
Schmallenburg Virus is very similar to Akabane Virus, except its distribution is confined to European countries.
True
