Journal ArticleDOI
Characteristics and Serologic Studies of Two Serotypes of Infectious Bursal Disease Virus in Turkeys
TL;DR: Two serotypes of infectious bursal disease virus (IBDV) were distinguished using the virus-neutralization test and virions of both IBDV serotypes were determined to be nonenveloped icosahedrons with diameters ranging from 58 to 60 nm.
Journal ArticleDOI
Nucleotide sequence analysis of genome segment A of infectious bursal disease virus.
TL;DR: The nucleotide sequence of genome segment A cDNA of the STC strain of infectious bursal disease virus (IBDV) was determined and compared with sequences of the homologous genome segment of the 002-73 strain of IBDV and the Jasper strains of infectious pancreatic necrosis virus.
Journal ArticleDOI
Studies on naturally occurring infectious bursal disease viruses suggest that a single amino acid substitution at position 253 in VP2 increases pathogenicity.
TL;DR: The molecular and pathogenicity data indicate that a single amino acid mutation from Histidine (H) to Glutamine (Q) or Asparagine (N) at position 253 in VP2 will markedly increase the virulence of an attenuated IBDV.
Journal ArticleDOI
Genetic characteristics of infectious bursal disease viruses from four continents.
TL;DR: The phylogenetic relationship of never-before-published IBDV from 18 countries on four continents is examined, placing putative vvIBDV strains from many different countries and geographic regions in a single clade with some minor non-significant branching.
Journal ArticleDOI
Classification of infectious bursal disease virus into genogroups
L.O. Michel,Daral J. Jackwood +1 more
TL;DR: A new classification scheme for IBDV is proposed based solely on genogroups identified from phylogenetic analysis of the hvVP2 of strains worldwide, suggesting that antigenic drift may be occurring in genogroup 3, possibly in response to antigenic pressure from vaccination.
