Parvoviridae Flashcards
parvo meaning
parvus - small
- one of the smallest viruses!
morphology
linear ssDNA - self priming hairpin ends, icosahedral, naked
resistance
(naked) very strong
replication
baltimore II - cellular polymerase, multiplication in dividing cells(foetus, intestine, bone marrow)
antigenic properties
very good ag’s - long immunity
cross reactions
cross immunity of related viruses - reaction between an antibody and an antigen that differs from the immunogen.
the 2 subfamilies of parvoviridae
parvovirinae densovirinae (infect arthropods so no vet importance)
the 5 genera of parvovirinae
parvovirus amdovirus bocavirus erythrovirus dependovirus
the 4 virus species of parvovirus genus
porcine parvovirus
Canine parvovirus 2
feline planleukoneia
mink enteritis
porcine parvovirus species: symptoms, genus
parvovirus - SMEDI:
- Stillbirth, Mummification, Embryonic Death and Infertility
(preads from foetus to foetus, abortion after last death(mummified foetuses, can identify the first dead foetus)
Canine parvovirus 2 species: symptoms, genus
parvovirus
- very contagious enteric disease* with vometing, dysentery(intestine inflammation)
- destroy int. villi -> bloody diarrhea
- myocarditis in puppies (death y dehydration)
feline planleukoneia species: symptoms, genus
parvovirus
- very contagious enteric disease with vometing, depression and diarrhea
- lymphoid tissue (WBC) -> immunosuppression
mink enteritis species: symptoms, genus
parvovirus
mink kittens - similar to feline planleukoneia
amdovirus genus: disease, symptoms
AMD - Aleutian Mink Disease
- persistant viraemia (virus enter blood)
- > plasmacytosis, hypergammaglobulinaemia
- > heorrage, nephritis
bocavirus genus; its 2 virus species
bo(vine)ca(nine)
bovine parvovirus
canine minute virus
