- orally or aerosol transmission
- incubation pd 5-35 days
Where does the paramyxovirus type 1 spread
Kidneys and/or CNS
Dx of paramyxovirus type 1 (4)
- clinical signs
- hemagglutination inhibition tests w/ paired sera of multiple pigeons
- histopath
- viral isolation
Dx & control of paramyxovirus type 1
