Herpesviridae Flashcards
herpes meaning
herpes - reptant, crawler
referring to spreading cutaneous lesions, usually involving blisters
morphology
linear dsDNA, enveloped(weak), icosahedral, big virus
latency
Episomes
- alphaherpesvirinae - neurons
- betaherpesvirinae - leucocytes
- gammaherpesvirinae - immune cells
replication
baltimore 1, nucleus
host specificity
euryxenous: pseudo-rabies
antigenic properties
(enveloped)weak - but can be fatal in immune supressed animals!
alphaherpesvirinae: genera, why alpha?
reproducing more quickly 4 genera: - simplexvirus - varicellovirus - mardivirus - iltovirus
simplexvirus: subfamily, affects which animals
Alphaherpesvirinae:
Bovine
monkey
human
bovine simplex, aka
Bovine herpesmamillitis (udder)
monkey simplex, aka
simian herpes (B-virus)
human simplex, aka
human herpes simplex: labial and genital herpes
varicellovirus, cause, imp. disease
abortion, respiratory, rabies(CNS) etc.
ND! Equine abortion/rhinopneumonitis
Aujeszky’s disease: subfamily, genus, aka
alpha, varicellovirus
pseudorabies
Mardivirus belong to what subfamily, affects which animals
genera of alphaherpesvirus
- chickens
- turkey
mardivirus in chickens
Marek’s disease, Gallid herpesvirus
mardivirus in turkey
turkey herpesvirus
iltovirus; which subfamily and which disease
alphaherpesvirinae
birds: infectious laryngotracheitis
- can be used in vaccines
Betaherpesvirinae; why beta, genera
slower reproductive rate than alpha, 3 genera: - cytomegalovirus - muromegalovirus - roseolovirus
Cytomegalovirus: which subfamily, and which animals
betaherpesvirinae
- human
- monkey
- elephant
Muromegalovirus: which subfamily, and which animals
betaherpesvirinae
- mouse
- rat
Roseolovirus: which subfamily, and which animals
Betaherpesvirinae
humans (fever and rash in children)
Gammaherpesvirinae: why gamma, their genera
most variable reproduction rate 3 genera: - Lymphocryptovirus - Rhadinovirus - Ictalurivirus
Lymphocryptovirus: subfamily, animals
Gammaherpesvirinae
- human
- monkey
- cattle
human Lymphocryptovirus aka
Epstein-Barr virus
- one of the most common human viruseses!
