  2. LEARNING OBJECTIVESStudents should be able to: • Relate the pathogenesis of feline infectious enteritis virus to its control • Explain the origins of canine parvovirus type 2 and its role in canine disease • Describe the importance and control of porcine parvovirus as a reproductive pathogen • List the species and disease conditions in which papilloma viruses are implicated

  3. FAMILY CHARACTERISTICS

  4. FELINE PARVOVIRUS DISEASE AND PATHOGENESIS:

  5. FELINE PARVOVIRUS DIAGNOSIS:

  6. FELINE PARVOVIRUS HOST RANGE : All felidae; mustelidae (mink) and some procyonidae (racoons and panda).

  7. FELINE PARVOVIRUS ANTIGENICITY & CONTROL:

  8. CANINE PARVOVIRUSTYPE 2

  9. CANINE PARVOVIRUSTYPE 2 DISEASE AND PATHOGENESIS: Infection via oropharyngeal route followed by viraemia. Initially, there were two distinct syndromes associated with CPV-2: (1) targeted at rapidly dividing myocardial cells, (2) at the rapidly dividing cells in the crypt epithelium of the small intestine.

  10. CANINE PARVOVIRUSTYPE 2 DIAGNOSIS:

  11. CANINE PARVOVIRUSTYPE 2 HOST RANGE Dogs (but CPV-2a & 2b can cause disease in cats - see below)

  12. CANINE PARVOVIRUSTYPE 2 ANTIGENICITY & CONTROL:

  13. PORCINE PARVOVIRUS DISEASE AND PATHOGENESIS

  14. PORCINE PARVOVIRUS HOST RANGE: pigs

  15. PORCINE PARVOVIRUS EPIZOOTIOLOGY:

  16. PORCINE PARVOVIRUS ANTIGENICITY & CONTROL:

  17. SUMMARY • Cause serious diseases in cats (enteritis/ panleucopenia), dogs (myocarditis/ enteritis) and pigs (SMEDI). • Pathogenesis is related to the requirement for rapidly dividing cells for virus replication • Vaccines available for each disease which prevent viraemia & hence destruction of rapidly dividing cells.
