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.
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
The causative agent, IPNV, is a bi-segmented double-stranded RNA virus belonging to the family Birnaviridae
The etiologic agent of IBD is a double stranded RNA virus belonging to the family Birnaviridae
The virus is a member of the family Birnaviridae
and the genus Avibirnavirus.
La enfermedad de Gumboro (IBD por sus siglas en ingles Infectious BursalDisease) es causada por un virus de la familia Birnaviridae
, genero Avibirnavirus el cual posee dos serotipos (1 y 2); los miembros de esta familia poseen un genoma que consiste en dos segmentos de una doble cadena de RNA (2, 80, 81).
Es causada por un Avibirnavirus de la familia Birnaviridae
, con un genoma compuesto por un ARN de doble cadena (Jackwood, 2009), estructurado por un segmento A que codifica para las proteinas virales VP2, VP3, VP4 y VP5, y por el segmento B que codifica para la proteina VP1 (Jackwood, 2009; Pan et al, 2009).
Causative agent of IBD belongs to family Birnaviridae
and genus Avibirnavirus [5, 6].
Infectious Bursal Disease Virus (IBDV) belongs to the family of Birnaviridae
, which consists of naked viruses characterized by a bi-segmented, double strand RNA genome and is the causative agent of a highly infectious disease affecting young chickens (Gumbro disease) (1).
O IBDV pertence a familia Birnaviridae
e genero Avibirnavirus (segundo ICTV 2011) e seu genoma consiste em dois segmentos de RNA de fita dupla (BANDA et al.
IPNV belongs to the Birnaviridae
family whose members are characterized by a genome which consists of two segments of double stranded RNA, A and B, and a naked icosahedral single-shelled capsid.
Infectious bursal disease virus, a dsRNA virus in Birnaviridae
family, was used as an outgroup.
