Clinical Effects

Epidemiology

Habitat

  • Distributed in intestinal tract of multiple mammalian species.
  • May be found transiently in feed and water.

Lifecycle

  • Ingestion of virus → infection of columnar epithelial cells of villi apices.
  • Intracellular multiplication of virus → cellular damage → villus atrophy.

Transmission

  • Feco-oral transmission.

Pathological effects

  • Cells at tips of intestinal villi destroyed; loss of brush-border enzymes leads to osmotic diarrhea Diarrhea: chronic.

Control

Control via chemotherapies

  • Supportive therapy:
    • Electrolytes, fluids.
    • Antibiotics to prevent secondary infection - debatable.

Control via environment

  • Sanitary and hygiene practices should minimize exposure.
  • Isolate pups with dam for at least 3 weeks post-partum, as this is the period of highest susceptibility to disease.
