Clinical Characteristics and Pathology

Detailed Clinical and Pathological Characteristics

General

WATERFOWL --

Clinical Characteristics

WATERFOWL Similar clinical signs to goslings with gosling parvovirus infection. Found huddling together, inability to walk, dragging of legs behind the duckling, and enteric signs. No feather loss (unlike goose parvovirus) (B12.55.w1, B32.37.w6, B32.31.w9).

Incubation

WATERFOWL --

Mortality / Morbidity

WATERFOWL Mortality up to 80% (B32.37.w6).

Pathology

WATERFOWL
  • Similar to goose parvovirus infection (B32.37.w6, B32.31.w9). 
  • Main finding is hepatopathy (B12.55.w1).

Susceptibility / Transmission

General information on Susceptibility / Transmission

WATERFOWL
  • Transmission: Horizontal; also vertical in ducks infected while in lay or if latent infection reactivates.
  • Susceptibility: Greatest in youngest ducklings infected in hatcher. Ducklings older than five weeks old seroconvert but do not show clinical signs.

General Investigation / Diagnosis

General Information on Investigation / Diagnosis

WATERFOWL
  • Clinical signs, gross and histological lesions, isolation of virus in muscovy duck embryos or muscovy cell culture, differentiation from GPV by cross-neutralization tests, serology or molecular methods. DPV antigen in tissues can be detected by a chemoluminescent dot blot assay using a non-radioactive, digoxigenin-labelled DPV DNA probe, but this also detects some GPV strains (B32.37.w6).
  • PCR-RFLP (polymerase chain reaction-restriction enzyme fragment length polymorphism) analysis can be used to differentiate from muscovy duck parvovirus from goose parvovirus (J5.42.w1).

WATERFOWL
  • Goose Parvovirus infection (GPV) (Goose Parvovirus Infection) differentiation by cross-neutralization tests or by PCR. Duck plague (DVE) (Duck Plague).
  • Muscovy duck reovirus infection (Reovirus Infection) (differentiated by absence of exudative pericarditis, tenosinovitis, splenic lymphoid hyperplasia).

Preventative Measures

Vaccination WATERFOWL Immunise breeders (two inoculations with oil-emulsion vaccine) to provide ducklings with maternally-derived antibodies; vaccinate day-old ducklings with inactivated, aqueous vaccine (B32.37.w6).
