Q

canine parvovirus

  1. types of dz virus causes
  2. method of transmission
  3. zoonotic?
  4. does it change/recombine/mutate
  5. distribution
  6. diagnosis
  7. differential diagnosis
  8. control
A
  1. enteritis, myocarditis
  2. 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
  3. no
  4. can mutate- used to be a feline dz that mutated into canine parvo. likewise, can be transm to cats
  5. smell, EM, fecal HA, ag capture ELISA, pcr on feces
  6. corona, rota
  7. vaccs!!! assoc with loss of maternal abs

Q

feline panleukopenia

  1. types of dz virus causes
  2. method of transmission
  3. zoonotic?
  4. does it change/recombine/mutate
  5. distribution
  6. diagnosis
  7. differential diagnosis
  8. control
A
  1. sudden fever, death, depression, enteric v/d
  2. trans via indirect (envt) or direct contact, body secretions, fecal - oral, in utero
  3. not zoonotic
  4. easily mutates- changed to canine parvo
  5. virus isolation, fecal pcr, ELISA (can use canine test, but not as sensitive)
  6. feline enteric coronavirus, rota, reo
  7. vaccinate

Q

porcine parvovirus (SMEDI?)

  1. types of dz virus causes
  2. method of transmission
  3. zoonotic?
  4. does it change/recombine/mutate
  5. distribution
  6. diagnosis
  7. differential diagnosis
  8. control
A
  1. affinity for actively dividing cells ex fetus so causes abortions in early prgnancy (<70 d)– (different from prrsv- late term abortions).
  2. transmission- fecal oral, transplacental, semen, ingestion, aerosol
  3. not zoonotic
  4. worldwide
  5. diagnosis via IFA on mummified piglets, HA (will agglutinate), virus isolation on fetus, pcr
  6. prrsv
  7. vaccinate, management
