Rotavirus disease

Contributor(s): Stephen Barr, Bryn Tennant

Introduction

  • Cause: canine rotavirus.
  • Signs: usually self-limiting diarrhea of brief duration.
  • Possibly severe enteritis in colostrum-deprived neonates, in conjunction with other pathogens.
  • Diagnosis: virus isolation from feces.
  • Treatment: symptomatic.
  • Prognosis: usually good, can be fatal in colostrum-deprived neonate.

Pathogenesis

Etiology

Predisposing factors

General
  • Suppressed immune system.
  • Colostrum deprivation.

Pathophysiology

  • Oral ingestion of virus → replication in enterocytes at tip of villi → villous blunting → enteritis.

Epidemiology

  • Fecal shedding of virus from infected dogs, with oral infection of susceptible dogs.
  • Antiviral antibodies have been demonstrated in up to 84% of dogs, indicating subclinical infection.
