The isolation, identification and characterisation of the causative agent involved in the "paralysis syndrome" and the implementation of suitable control measures

Abstract

"Paralysis syndrome" was first described by Dr M.J Versveld in 1993. The disease appeared to be confined to the Natal area with a few sporadic outbreaks in Gauteng, but none in the Cape region, nor in non-Rainbow flocks. The syndrome tended to re-appear on affected farms but not necessarily in the same houses. There was no correlation between affected flocks and their parent flock or hatchery identity (Maharaj, pers.comms.1994).
