Reovirus Flashcards
Orbiviruses spread by droplet (aerosol) infection
F
Orbiviruses can be cultivated in vivo by inoculation of embryonated eggs
T
Genetic reassortments may cause significant antigenic changes in reovirus strains
T
Orbiviruses are serologically uniform
F
Orbiviruses are mainly arboviruses

F
Orthoreovirus can cause tenosynovitis in pigs
F
Avian orthoreoviruses usually cause disease in adult birds
F
Tenosynovitis is one of the most frequent manifestations of avian orthoreovirus infections
T
