A disease of turkeys caused by the viruses of the Pneumovirus genus, Paramyxoviridae. Morbidity is 10-100% and mortality 1- 30%. Rapid transmission occurs laterally, possibly involving fomites; vertical transmission is uncertain, maternal antibody may protect.
- Decreased appetite, weight gain and feed efficiency.
- Loss of voice.
- Ocular and nasal discharge.
- Serous rhinitis and tracheitis, sometimes pus in bronchi.
- If there is secondary E. coli infection then pneumonia, airsacculitis and perihepatitis.
Clinical signs, serology (using an Elisa test to demonstrate rising titre), isolation and identification of the ciliostatic virus.
Antibiotics are not very effective, control respiratory stressors, chlorinate drinking water.
All-in/all-out production. Vaccination at day-old seems to be most effective.
