The IBD etiological agent is double stranded RNA virus having two segments which belongs to the Birnaviridae family and consisted of two serotypes, designated as serotypes 1 and serotype 2 (Carballeda et al., 2011).
The etiologic agent, IBD virus (IBDV), is a naked icosahedral virus having segmented double stranded RNA genome belonging to the genus Avibirnavirus, family Birnaviridae [1].
The 4 exceptions comprise 2 families that have no known human-infective viruses (Arteriviridae and Birnaviridae) and 2 with species that have been reported in humans but only at level 2 (Asfarviridae and Bornaviridae).
IBD is an acute and highly contagious viral disease which affects both broilers as well as layers caused by Infectious bursal disease virus (IBDV), a double stranded RNA virus belonging to the family Birnaviridae (2).
The causative agent, IPNV, is a bi-segmented double-stranded RNA virus belonging to the family Birnaviridae. Control methods currently rely on the implementation of control policies and hygiene practices in salmonid husbandry, through the avoidance of the introduction in fertilized eggs originating from IPNV-carrier brood stock, and the use of a protected water supply.
