Pathogenicity of SspI-positive infectious bursal disease virus and molecular characterization of the VP2 hypervariable region

Cloning and Codon-optimized Expression of Structural Protein Hypervariable Region of VP2 from Infectious Bursal Disease Virus

Infectious bursal disease virus (IBDV) is the causative agent of Gumboro disease, an infectious disease of global economic importance in poultry. Structural protein VP2 of IBDV is the most frequently studied protein due to its significant roles in virus attachment, protective immunity, and serotype specificity. The objective of the present study was to improve the expression of hypervariable re...

Molecular characterization of two Bangladeshi infectious bursal disease virus isolates using the hypervariable sequence of VP2 as a genetic marker

Two Bangladeshi infectious bursal disease virus (IBDV) isolates collected in 2007, termed GB1 and GB3, were subjected to comparative sequencing and phylogenetic analyses. Sequence analysis of a 474-bp hypervariable region in the VP2 gene revealed that among four major amino acid substitutions observed in the strains, two were unique to GB1 and GB3 (Ser217Leu and Ala270Thr) while one substitutio...

Cloning and Expression of VP2 Gene of Infectious Bursal Disease Virus in Eukaryotic Cells

Infectious bursal disease (IBD) is an economically important viral disease of chickens with worldwide distribution which suppresses the immune system of young chickens. VP2 is the major host-protective protein of infectious bursal disease virus (IBDV). The encoding region of VP2 protein was PCR amplified from a plasmid containing a cDNA fragment of large genomic segment of IBDV, strain D78. Thi...
