Viro: Arteriviridae Flashcards
Family of virus that is Enveloped, spherical, nucleocapsids are isometric
Arteriviridae
What glycoprotein spikes do Arteriviridae have?
Small and indistinct glycoprotein spikes compared to
prominent spikes of coronaviruses
Genome of arteriviridae
Single molecule of linear positive-sense; ssRNA
How many nucleocapsid protein and envelope protein do they have?
Has 1 nucleocapsid protein (N) and 7 envelope
proteins (E, GP2, GP3, GP4, ORF5a, GP5 and M)
Arteriviridae replicate where?
Replicate in macrophages
Arteriviridae causes diseases like?
Equine Arteritis Virus & Porcine Reproductive and Respiratory Syndrome Virus
Virus that is also called “pinkeye” , “infectous or
epizootc cellulites”, “infuenza erysipelatosa”
and “Pferdestaupe
Equine Arteritis Virus
Equine Arteritis Virus is spread through?
Spread by both the respiratory and venereal
routes
Initial replication of Equine Arteritis Virus takes place in?
Inital replication takes place in alveolar
macrophages and endothelial cells afer
aerosol respiratory infection
Lesions of Equine Arteritis
edema, congeston,
hemorrhage
Causes Progressive “pneumo-enteric” syndrome,
“aborton storms”
Equine Arteritis
Initially designated as “mystery swine
disease”

infectious aerosols, ingestions of
virus contaminated food
Porcine Reproductive and Respiratory Syndrome lesions:
