Clinical Effects



  • Generally it is distributed in the intestinal tract of multiple mammalian species.
  • However, rotavirus can also be found transiently in feed and water.


  • Once the virus is ingested it is able to survive the low gastric pH and infects the columnar eipthelial cells of villi apices.
  • Viral multiplication happens intracellulary with extensive cellular damage.


  • Feco-oral transmission: the virus is shed in the feces of infected rabbits.
  • Transmission by aerosol has been reported in mice but not confirmed in rabbits.

Pathological effects

  • The virus destroys the enterocytes of intestinal villi. The loss of brush-border enzymes leads to osmotic diarrhea.
  • Histologically, villous atrophy and desquamation and degeneration of the enterocytes on the tips of the villi are present.
  • Secondary infections occur often due toClostridiumspp   Clostridium difficile    Clostridium piliforme   andE. coli  Escherichia coli  .


Control via animal

  • There is no treatment or cure for the rotavirus. However, the infection appears to be self-limiting if young rabbits are not introduced into the infected colony.
  • Experimentally, the virus is shed in the feces for one week. Therefore, it appears that the infection due to rotavirus could be controlled by temporary cessation of breeding for 4-6 weeks.

Control via chemotherapies

  • There is no cure for the virus itself. Supportive therapy will improve the life quality of the infected rabbit while the disease runs its course.
  • The osmotic diarrhea caused by the viral infection leads to the loss of fluids and electrolytes. Supplemental electrolytes must be provided to restore the fluid balance   Fluid therapy  .
  • Antibiotics   Therapeutics: antimicrobials   should also be administered to prevent secondary infection.

Control via environment

  • Sanitary and hygiene practices should minimize exposure.
