Background:
Infectious bursal disease virus (IBDV) is a highly contagious immunosuppressive virus of chickens. Chickens acquire infection by the oral route under natural conditions. Although the histological and pathological changes after IBDV infection are well described, the alterations in serum metabolome have not been reported. In this study, SPF chickens were infected with attenuated IBDV (atIBDV) strain LM and very virulent IBDV (vvIBDV) strain LX, respectively. On the seventh day after oral infection, serum samples of experimental chickens were identified using ultra-high performance liquid chromatography-MS/MS (UHPLC-MS/MS). The serum metabolic profiles were analyzed by multivariate statistical methods. KEGG enrichment analysis was performed to evaluate the dysregulated biological pathways.
Results:
We identified 368 significantly altered metabolites in response to both atIBDV and vvIBDV infection. The metabolic disorder of amino acid and lipid was associated with IBDV infection, especially tryptophan, glycerophospholipid, lysine, and tyrosine metabolism. The differential metabolites enriched in the four metabolic pathways were PC(20:4(5Z,8Z,11Z,14Z)/18:0), PE(16:0/18:2(9Z,12Z)), PE(16:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)), PE(18:0/20:4(5Z,8Z,11Z,14Z)), PE(18:0/20:4(8Z,11Z,14Z,17Z)), PE(18:0/22:6(4Z,7Z,10Z,13Z,16Z,19Z)), PE(20:3(8Z,11Z,14Z)/16:0), PE(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/16:0), PE-NMe(20:5(5Z,8Z,11Z,14Z,17Z)/18:0), PS(20:3(5Z,8Z,11Z)/18:2(9Z,12Z)), 2-aminobenzoic acid, 4-(2-aminophenyl)-2,4-dioxobutanoic acid, N-acetylserotonin, 5-hydroxyindoleacetate, indole-3-acetaldehyde, indole-3-acetate, p-coumaric acid, L-tyrosine, homovanillin, and S-glutaryldihydrolipoamide.
Conclusion:
The atIBDV and vvIBDV infection causes metabolic changes in chicken serum. The differential metabolites and dysregulated metabolic pathways reflect the host response to the IBDV infection.

The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
