parvoviridae Flashcards
1
Q
general characteristics of parvoviridae
genetic material
enveolped?
viruses
A
ssDNA
Nonenveloped (STABLE)
canine parvo
feline panleukopenia
porcine parvo
human parvo
2
Q
canine parvovirus
- types of dz virus causes
- method of transmission
- zoonotic?
- does it change/recombine/mutate
- distribution
- diagnosis
- differential diagnosis
- control
A
- enteritis, myocarditis
- fecal oral/fomites/ contact/ req dividing cells in S phase for replication (start in lymphoid tissue). dev viremia and virus will enter bone marrow, lymph tissue, crypt cells
- no
- can mutate- used to be a feline dz that mutated into canine parvo. likewise, can be transm to cats
- smell, EM, fecal HA, ag capture ELISA, pcr on feces
- corona, rota
- vaccs!!! assoc with loss of maternal abs

Q
feline panleukopenia
- types of dz virus causes
- method of transmission
- zoonotic?
- does it change/recombine/mutate
- distribution
- diagnosis
- differential diagnosis
- control
A
- sudden fever, death, depression, enteric v/d
- trans via indirect (envt) or direct contact, body secretions, fecal - oral, in utero
- not zoonotic
- easily mutates- changed to canine parvo
- virus isolation, fecal pcr, ELISA (can use canine test, but not as sensitive)
- feline enteric coronavirus, rota, reo
- vaccinate
4
Q
porcine parvovirus (SMEDI?)
- types of dz virus causes
- method of transmission
- zoonotic?
- does it change/recombine/mutate
- distribution
- diagnosis
- differential diagnosis
- control
A
- affinity for actively dividing cells ex fetus so causes abortions in early prgnancy (<70 d)– (different from prrsv- late term abortions).
- transmission- fecal oral, transplacental, semen, ingestion, aerosol
- not zoonotic
- worldwide
- diagnosis via IFA on mummified piglets, HA (will agglutinate), virus isolation on fetus, pcr
- prrsv
- vaccinate, management
