Poxviridae Flashcards
pox meaning
pock - scar
elevation of skin ->elevation w/fluid -> scab -> scab
morphology
linear dsDNA, complex capsid, enveloped
resistance
(enveloped!!)good, though chloroform inactivates all poxviruses
replication
baltimore 1, multiplication in CYTOPLASM!!
host specificity
zoonoses in which pox genuses: (transmission btw human and animal)
- orthopoxvirus and parapoxvirus(sheep, goat and cattle)
infection how
airborne, contact, arbo (arthropod)
antigenic properties
good, long immunity
except parapox
subfamilies of poxviridae
chordopoxvirinae (all genuses are in this subfamily!)
entomopoxvirinae (insects - no veterinary importance)
orthopoxvirus genus: meaning, its 7 virus species
ortho - real 1 - cowpox/pseudopox 2 - buffalopox 3 - camelpox 4 - ectromelia (mousepox, loss of legs) 5 - variola (smallpox, eradicated!) 6 - vaccinia virus 7 - monkeypox
variola and vaccina connection
vaccinia virus is a mutant cowpox virus used to vaccinate smallpox, cross neutralization! (used to eradicate smallpox)
parapoxvirus genus: symptoms
scabs, skin infections
avipoxvirus: symptoms, which virus species, transmission
scabs, pneumonia
arthropod transmission
capripoxvirus genus: disease
ND! lumpy skin disease (LSD) cattle in africa (abortion)
Leporipoxvirus genus; affect which animals, disease
ND! myxomatosis virus (tumor in rabbit)
tumors in rabbit, hares (fibromas)
Suipoxvirus genus; animal, symptoms, transmission
occur worldwide in swine
skin disease
transmitted by pig louse
