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.
