Effect of age on the pathogenesis of DHV-1 in Pekin ducks and on the innate immune responses of ducks to infection.

Duck hepatitis virus (DHV) affects 1-week-old but not 3-week-old ducks, and it causes a more severe disease in the younger ducks. These differences may be partially due to the host response to DHV infection. In order to understand this difference, we characterized the pathobiology of and innate immune response to DHV infection in 1-day-old (1D) and 3-week-old (3 W) ducks.

Immunoproteomics analysis of whole cell bacterial proteins of Riemerella anatipestifer.

Riemerella antipestifer is one of the most important duck pathogens. It has worldwide distribution, and the lack of the information on bacteria-host interactions and an effective vaccine are limitations on the control of this infection. In this study, an immunoproteomic assay was used to identify immunogenic proteins among the whole cell bacterial proteins of R.
