摘要:Despite the application of live hemorrhagic enteritis virus (HEV) vaccines, HEV field outbreaks are suspected to still occur in turkey flocks in Germany. Increasing secondary bacterial infections in HEV-vaccinated flocks suggest that vaccines may be losing efficacy or, possibly, ...

摘要:A healthy immune system is a cornerstone for poultry production. Any factor diminishing the immune responses will affect production parameters and increase cost. There are numerous factors, infectious and noninfectious, causing immunosuppression (IS) in chickens. This paper revie...

摘要:Marek's disease virus (MDV) is an alphaherpesvirus that causes Marek's disease (MD), a lymphoproliferative disease in chickens. Understanding of MDV gene function advanced significantly following the cloning of the MDV genome as either a series of overlapping cosmids or as a bact...
