Introduction
Rotavirus infection is seen in chickens, turkeys, guinea fowl, pheasants, partridges and pigeons. The route of infection is oral and maximum viral excretion occurs 2-5 days post infection. It is not known if vertical transmission occurs though virus has been occasionally isolated from embryonated eggs.
Signs
- Diarrhoea.
Post-mortem lesions
- Viruses replicate mainly in the mature villous epithelial cells.
Diagnosis
Demonstration of virus (PAGE, electron microscopy or Elisa on intestinal contents – submit 6 x .5 g faeces). Virus may be found in asymptomatic birds.
Treatment
No specific treatment for this infection. Control of secondary bacterial enteritis may require antimicrobial medication. Use of a good electrolyte solution is beneficial in the acute stage of infection.
Prevention
Good hygiene in brooding areas.
