Rotavirus disease
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.
Presenting signs
- Self-limiting mild diarrhea.
Acute presentation
- Severe enteritis.
Age predisposition
- <4 weeks old.
Pathogenesis
Etiology
- Canine rotavirus Canine rotavirus.
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.
